=== Thargoid is now known as stwalkerster [00:06] Having issues getting 3.5mm speaker to play audio on a Raspberry Pi 3B running Ubuntu 18.02.2 LTS. I've installed alsa-utils, but the command "amixer cset numid=3 1" fails with "amixer: control default open error: no such file or directory" and aplay -l outputs "no soundcards found..." [00:06] I've also removed pcspkr from /etc/modprobe.d/blacklist.conf and run "modprobe snd_bcm2835". Any suggestions? [00:07] FreeBDSM: give it a try. for module in nvidia nvidia_modeset nvidia_uvm nvidia_drm; do echo $module | sudo tee -a /etc/initramfs-tools/modules && sudo update-initramfs -k $(uname -r) -c [00:07] I've installed jack (the audio platform) on Ubuntu, but sounds seem to be much softer than on ALSA/PulseAudio [00:08] `gst-launch-1.0 audiotestsrc freq=200 volume=1.0 ! alsasink` is loud [00:08] `gst-launch-1.0 audiotestsrc freq=200 volume=1.0 ! jackaudiosink` is faint [00:08] FreeBDSM: then access grub and manually add the nvidia-drm.modeset=1 !kernelparm [00:08] !kernelparm | FreeBDSM [00:08] FreeBDSM: To add a one-time or permanent kernel boot parameter see https://wiki.ubuntu.com/Kernel/KernelBootParameters [00:08] Is there some kind of volume knob for the PulseAudio -> JACK bridge? [00:09] univern what distro are you running? I'm trying to get beeping to work on a Pi 3b with no success [00:09] on 19.04 with nvidia what do i have to do to make it remember my display setup correctly after a reboot? it seems to be struggling with the concept of the primary display being the one in the middle === ekaj89 is now known as ekaj_ [00:10] i go into nvidia-settings, arrange the 3 of them how i want them, apply it, verify that its correct, and then save it to xorg.conf, and after a reboot its no longer how i had it set [00:11] makes no sense to me [00:11] ekaj89: Ubuntu 18.04 for x86 [00:11] Haven't tried on a Pi :) [00:17] jeebus finally got it to work [00:18] what was it? [00:20] tomreyn: Thanks. But what's the difference between update-grub and update-grub2? [00:21] FreeBDSM: the latter ends with a 2 [00:21] tomreyn: :) [00:21] readlink -f $(which update-grub); readlink -f $(which update-grub2) [00:22] yeah, just noticed /usr/sbin/update-grub2 -> update-grub [00:22] the script could still behave differently basedon how it was run, but IIRC this one does not [00:23] had to add a line to /boot/firmware/config.txt, then modprobe bcm_2835. "beep" doesn't play a sound , but if i install sox i can use "play" to play tones [00:23] tomreyn: which script? the one-liner that adds modules to /etc/initramfs-tools/modules? [00:23] FreeBDSM: the 3-liner that is /usr/sbin/update-grub [00:42] afaiu, enabling drm kms didn't work === pcworld is now known as Keksdose === Keksdose is now known as pcworld [01:03] earlier one of my netbooks mostly froze because apparently the kernel was way to eager to try and cope although for my gut feeling it was clearly out of memory. I noticed because the tray clock was about 20 minutes behind my wall clock, so I forced two OOM kills as usual (it happens every few months). I have several processes that I like to keep around if possible but are never worth blocking user interaction, so can I start them in a [01:03] way that the kernel knows to sacrifice them as soon as it's a bit in trouble, way before it would have to give up and OOM-kill on its own? [01:07] Sven_vB: yes, you can change their /proc/$pid/oom_score_adjust [01:08] deltab, thanks! which side of the scale is killed first? [01:09] or you can set a limit using ulimit or cgroups [01:09] well as long as there's no problem I want them to roam freely. [01:09] https://askubuntu.com/questions/60672/how-do-i-use-oom-score-adj [01:11] http://man7.org/linux/man-pages/man1/choom.1.html [01:12] thanks! [01:15] hi, I solved my problem (bandwidht limitation) passing a parameter when loading the wifi module with something like the following: rmmod ath10k_pci && modprobe ath10k_pci ant_sel=2 [01:16] "The value is inherited for child processes." might be a problem because the toplevel process of the expendible services usually is a bash script that loops infinitely. [01:16] MMYStic: oh cool! thanks for reporting back [01:17] I'll search for how to detect whether a child process was OOM-killed [01:17] Sven_vB: the closest is the parent can see that the child was killed via signal [01:17] Sven_vB: to find out that it was killed by OOM you have to search through dmesg [01:18] sarnold, is it a specific signal? [01:18] Sven_vB: no [01:18] :< [01:18] Sven_vB: it'll be consistent, of course; probably it's SIGKILL. but you can send the same signal by hand [01:19] yeah I can live with that. I trust anyone who'd do that has a better reasons than the looping script has for looping again. [01:20] I'll try and find some syslog entries about why it took more then 20 mins of freezing and the kernel still hadn't given up [01:21] I suspect hard OOM condition is way too late for my liking. [01:22] it'd definitely be worth trying to fix whatever the actual problem is :) trying to fiddle with magic scripts and oom adjustments etc is recipe for more instability some point in the fuiture [01:26] yeah, I fixed the most common problem, me forgetting to close VLC before I upgrade apt packages. my upgrade script now checks for free memory. still there may be other things I could forget need lots of RAM. [01:26] or things of whom I didn't even anticipate they'd need so much RAM. [01:27] also why should I as a human have to take care if my kernel could do it for me. :) [01:27] the kernel does not have many options [01:27] it can either swap anonymous memory to disk (probably why it was slow for twenty minutes) [01:27] or it can kill processes [01:28] or it can return *failure* on memory allocation requests a lot earlier (guess how many programs handle that gracefully :) [01:29] I don't have a swap, and yeah as long as some of my luxury processes are running, it's my express wish to rather kill them if it can help prevent a freeze. [01:29] no swap?? ouch [01:29] Speaking of VLC, every time I run VLC, it starts with 0 volume. With VLC's output set to Pulseaudio, there is no option to save volume. Therefore, every time I try to play a file (whether from CLI or Nautilus), the vol starts at zero. Is there a way to fix this? [01:30] I never found a reasny why I'd want a swap. I have enough RAM for everything that's important to me. [01:30] Sven_vB: apparently you don't :) [01:31] sarnold, yes I had. when I noticed the freeze I immediately knew which processes should have been killed 20 mins ago because they were not important enough to me. [01:31] "enough memory" would mean never seeing a slowdown in the first place [01:31] sarnold, slow internet? [01:32] sarnold, depends [01:32] I'd rather not use disk space just to help semi-worthless proceses survive. === zbenjamin is now known as Guest62824 === zbenjamin_ is now known as zbenjamin [01:40] I might need a custom watchdog anyway, as syslog shows no signs of the kernel considering the system to be "really OOM" at any point. [01:40] and I can't use cron for that because cron jobs were not run in that time. [02:10] starting today ubuntu freezes up after i login in and i have to fprce reset it [02:12] is this only happens after the desktop fully loads [02:27] hey quick question (sorry if this is the wrong place to ask first time here): Im trying to enable memory ballooning but i cannot turn off large pages to begin the process as i cannot get the appropriate UUID, i have been using # /usr/sbin/dmidecode | grep UUID to attain it but get an error saying its incorrect [02:30] distant: if you don't get any answers here in the next few minutes, try again in #ubuntu-server -- I suspect that group will have more experience here [02:30] distant: (but it's also less active, so maybe stick around for hours, ask again every few hours, etc) [02:34] distant: why can't you use blkid [02:35] distant: or you can use sudo blkid if you don't know what device [02:36] I have just downloaded 18.04.2 ... I copied it to a flash drive .. when I try to boot the computer from the flash drive I get the error "isolinux.bin missing or corrupt" ... so how do I get past this? [02:37] neildugan: what software did you use to put the image on the usb stick? [02:37] blue1, dd [02:38] blue1, dd if=ubuntu-18.04.2-desktop-amd64.iso of=/dev/sdb bs=4096 [02:38] neildugan: that is what I use what was the command line you used? something like sudo dd if=filename.iso /of=/dev/devicename bs=4M [02:39] blue1, snap [02:39] well forget the /of - its just of === [b0b] is now known as b0b [02:40] blue1, I checked the sha1 signature too [02:40] blue1 thank you for the response, the UUID generated from sudo blkid generates the same UUID as # /usr/sbin/dmidecode | grep UUID which unfortunetly gives the same error "VBoxManage: error: Could not find a registered machine named xxxxx [02:41] blue1, the command I used didn't have the /of just of I don't know where that came from [02:42] distant: I am not familiar with VM's -- sound like that might be the issue. [02:42] okie doke np [02:42] neildugan: you might try another flashing software -- I have had some problems with dd -- that absolutely should have worked. Let me see what other software I used. [02:43] distant: are you sure vbox does balloon? [02:44] distant: Humm a thought as you have "registered machine named xxxxx [02:44] neildugan: I used ddrescue [02:45] yup i double checked, im using version 6.0 64bit [02:45] neildugan: I had problems with getting dd to work with a raspberry pi image - ddrescue worked for me. [02:45] YMMV applies [02:45] " is it that the code looks for the name as referenced in /etc/hostname ? [02:50] hi [02:50] what does the 'live-server' download type do? [02:53] neildugan: it's just another way to install ubuntu https://help.ubuntu.com/lts/serverguide/installing-live-server.html [02:53] sarnold, ok [02:54] is there a link I can download 18.04.01 from ... all I can find is links for 18.04.2 [02:55] neildugan: probably not [03:02] neildugan: Yup ! See: http://old-releases.ubuntu.com/releases/18.04.1/ . [03:03] Bashing-om, thanks [03:03] Bashing-om: thanks -- I didn't know that. [03:05] neildugan: blue1 : Glad to help :) [03:09] neildugan: be careful with those, the apt in them was vulnerable to a mitm attack https://justi.cz/security/2019/01/22/apt-rce.html [03:15] sarnold: Assigned CVE-2019-3462 - is apt not now patched ? for my edification :D [03:16] Bashing-om: it is, and the fix is on the 18.04.2 disc images, but not the 18.04.1 disc images [03:16] sarnold: ouch ! thanks ! [03:21] When I am running speedtest-cli I get a download speed of 0.00 Mbit/s. Is that possible? I am connected over WLAN to a router of Vodafone Kabel Deutschland (cable connecion original made for TV signals, Germany). [03:46] hi guys! [03:51] blue1, Bashing-om , so far I haven't been able to get 18.04 or 18.04.2 or 19.04 to boot [03:52] neildugan: rpi? [03:52] neildugan: Verified the download ? How did you make the image ? verified the image ? [03:52] neildugan: I got the live server image to work on my rpi3b no trouble [03:53] sarnold, no a full amd64 motherboard. [03:53] neildugan: d'oh. I wonder what I was remembering.. [03:55] Bashing-om, I did verify some of the images before coping to the USB drive the 18.04 give the "isolinux.bin missing or corrupt" error the 19.04 says "invalid kernal command" [03:58] Bashing-om, I created the images by useing dd to a USB flash drive [03:58] neildugan: I would take "isolinux.bin missing or corrupt" as the truth in that the image is corrupt . Got another machine that you can try and boot with that USB ? [04:01] neildugan: " sudo dd if=/path/to/iso of=/dev/sdX bs=4M && sync " is the command you ram to make the image ? [04:15] Bashing-om, the 'sync' seems to be the missing piece it seems to be booting now... that was about 2 hours wasted. [04:16] neildugan: :) - the sync is just to make sure the buffer is written out - else wait a long time to make sure the write completes :) [04:17] Bashing-om, I did notice it took a while. Now I can see if I can repair the grub. [05:20] does htop display total cpu? i only see usage of processes but not overall [05:33] i'm on bionic and denyhosts isn't doing anything to a fail to authenticate from a remote host a whole bunch of times. it's configured to monitor /var/log/auth.log and i can for sure my failed auth attempts there, but it never seems to make note of it in /var/log/denyhosts or update /etc/hosts.deny or block anything [05:39] i see plenty of entries in /var/log/auth.log along the lines of ''sshd[19307]: Connection closed by authenticating user root 206.189.65.3 port 47102 [preauth]'' from my cloud vm *shrug* [05:50] Hi, is there any channel for opera android ? [05:50] my client cannot list any existing channel [05:52] Is there any VPN option for opera android ? [06:00] can you mount a stopped lxc container image and read its filesystem === macroprep_ is now known as macroprep === macroprep_ is now known as macroprep [06:18] Windows 10 allows one to "Add Mirror" to logical volumes (i.e. software implementation of RAID-1). If I do that, will these drives still be readable by Ubuntu? [07:00] hello ubuntu , im having problem to install ubuntu 19 on my laptop dell n5010 does someone know why? [07:02] the 64 bit version only have problem, the 32 bit works well. [07:04] Hey, I'm still trying to get my ultrawide monitor to work with Linux. I ended up updating the Intel drivers. Which didn't fix the issue. Any ideas? [07:06] LaserAllan_: be helpful if you explained what version of "linux", what the problem is beyond "not working" and how you updated the linux drivers [07:07] Oh sorry [07:07] can someone help me ? [07:08] bryanroderyck, ubuntu 19? do you mean 19.04? and what 32bit version do you mean works well? [07:09] I'm using Ubuntu 1804, I added the PPA ppa:oibaf/graphics-drivers. The monitor in question is the Dell u4919dw and it has a resolution of 5120*1440. However, I can't seem to go any higher than 4840"1080, if I do it'll basically not give me any desktop but I still have signal. [07:10] guiverc, yes the 19.04 does boot from usb, the ubuntu 16.04 32 bit work well on th dell n5010. [07:12] LaserAllan_: so have you looked at the requirements for that resolution eg: does it require anything special to get that resolution, eg: on nvidia, it may need g-sync, [07:13] LaserAllan_: have you looked at the xorg logs to see what happens when you set it to a higher resolution, what does the display server think/say it's doing [07:13] bryanroderyck, did you check-disc-for-defects (to ensure ISO download & usb/cd/dvd write was perfect)? [07:13] ikonia: not as far as I know. I installed Windows and there it works. So it's not related to that [07:13] LaserAllan_: that means nothing [07:14] LaserAllan_: the windows drivers are actually different than linux and the display server works in a different way [07:14] ikonia: I looked at that this morning. There were no xorg logs in /var/log [07:14] Alright then I'll discard that then [07:14] LaserAllan_: so there is no Xorg.0.log or anything like that in /var/log [07:15] That's correct [07:15] LaserAllan_: there is also the local session log in $HOME/.local/share/xorg [07:15] ikonia: I haven't looked there yet. I'll do that when I get home. [07:17] ikonia: I'll get back to you on that when I get home. It'll sadly be about 11 hours. I should also say that I'm using USB-C from the screen. === bleb is now known as bleb_ [08:06] LaserAllan_: if you can attach the screen via classic hdmi or displayport rather than usb-c this may be worth a try (if only to reduce complexity a little). also try without PPAs, with !HWE kernel *and* X, with a 19.04 live iso, with xwayland, or with this alternative PPA https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/mesa (though versions and packages look quite similar to oibaf's) [08:06] but indeed, check logs first of all. [08:07] journalctl -b returns the full system log since the latest boot (q to quit), including X logs. you may note that X starts twice, one time for the login manager, another for the actual desktop after login. === imsurit_ofc is now known as imsurit [08:19] Hey, is there a way to disable completely this ubuntu 19.04 update check? The option in software properties seems to have no effect at all. [08:19] I'm updating my system everyday anyway, via cmdline. [08:30] Furai: software-properties-gtk --open-tab=2 -> Automatically check for updates: never. You could uninstall (purge) update-notifier-common, but this would also remove several other packages. and there may be a better approach. [08:31] tomreyn, that's exactly when I have changed it to never. [08:31] And when I update I never just leave `apt update` hanging without actually installing. [08:32] Furai: oh you said the setting has no effect, sorry, still waking up here. [08:32] Unless it works and this is just the update notifier and the update check happens somewhere else. [08:33] Like in some on init scripts when booting up. [08:33] Dunno, really it's just annoying to see that pop-up, that's all. Nothing serious. [08:33] And it's only annoying cause I'm handling updates myself. [08:34] on 18.04.2, there are two systemd timers for apt which also trigger apt hooks. [08:34] apt-daily.timer + apt-daily-upgrade.timer [08:35] (according to systemctl list-timers) [08:35] hmm [08:36] personally i install security updates automatically (no prompt), have the system prompt me about non security updates once a week. that's not annoying. [08:36] that's on a desktop [08:39] "/lib/systemd/system/apt-daily.service" runs "/usr/lib/apt/apt.systemd.daily update". "/lib/systemd/system/apt-daily-upgrade.service" runs "/usr/lib/apt/apt.systemd.daily install" [08:42] Furai: so i guess that if you disable Update-Package-Lists in /etc/apt/apt.conf.d/10periodic (which would be equivalent to running 'sudo apt update') you'll get no notifications. [08:43] tomreyn, thanks, let me check that. I remember editing some post "apt update" hook which was triggering update notifier. [08:43] But for sure I haven't touched the periodic ones. [08:44] Anyway, this is counterintuitive like with whole linux world. The GUI is just an afterthought to everything below. You'd expect it to actually work when you just choose "never". [08:45] Uh, I had that disabled. I remember looking at that file. [08:49] Furai: see also bug 1834226 [08:49] bug 1834226 in software-properties (Ubuntu Eoan) "update-notifier doesn't respect "automatically check for updates: Never"" [High,New] https://launchpad.net/bugs/1834226 [08:50] fixing this seems to be in the works [08:50] the id-... tag added there refers to a canonical task tracker, i think [08:51] Furai: and yes, bugs can be counter intuitive, both in the linux world and elsewhere. [08:52] if you'd prefer a more polished user experience, use LTS releases [08:53] Mkey, will subscribe to that issue and click that it affects me. [08:53] will give it some "importance" points. [08:54] Went from 8 to 20. [08:54] 22 now ;) [08:54] haha, thanks [08:56] Bionic/LTS suffers from the same problem, and this issue has already been filed in the past. [08:57] Furai: generally, when you are certain something is a bug, please do look for bug reports, and, if there is none, report it (using ubuntu-bug PACKAGENAME). that's how we can support the developers in supporting us. [08:57] bug 1832882, this one is also kind of annoying, but since I've just switched to web based spotify and I'm ok with it. [08:57] bug 1832882 in curl (Ubuntu Disco) "libcurl-gnutls segfaults spotify client" [High,Confirmed] https://launchpad.net/bugs/1832882 [08:58] And what if application crashes? There's not much documentation on using apport or whatever it was. [08:58] Whoopsy? [08:58] Can't remember. [08:59] whoopsy is almost fully automated, should just show this prompt you know by default. [08:59] Unless in privacy I have checked something that forbids my system to send data to ubuntu... [08:59] Which I might have. [08:59] right [09:00] Anyway, tutorial really wouldn't hurt. [09:00] !bug | Furai [09:00] Furai: If you find a bug in Ubuntu or any of its official !flavors, please report it using the command « ubuntu-bug » - See https://help.ubuntu.com/community/ReportingBugs for other ways to report bugs. [09:00] Thanks. [09:01] you'll find a lot of documentation (sadly some is outdated) on help.ubuntu.com and wiki.ubuntu.com, also with a web search. [09:02] Yeah, I think I saw this one, tried following it but was confusing/outdated. [09:02] I can always go and start new bugreport on launchpad [09:02] But what's good it is if I don't have any data to support my claim? [09:03] Oh, and recently I've talked my older brother try Ubuntu during the time when his macbook is being fixed. [09:03] The biggest complaint from him was lack of hibernation [09:04] this data is not just needed to support your claim but for developers to analyze the situation and understand what the root cause is [09:04] Overall he said that system made a long way since the last time he tried it. [09:04] But even things like connecting bluetooht devices or using wireless printer were giving him a hard time. [09:05] tomreyn, yeah I'm aware of that. I'm kind of developer/more of a support guy for our games. [09:05] So I know the pains of bad bugreports. [09:05] s/bluetooht/bluetooth/ [09:06] hibernation is generally supported. it doesn't always work, thoough, mostly due to firmware bugs (where the firmware doesn't exhibit its full functionality to non windows systems) and also due to a secure boot hen and egg problem. [09:06] consider using suspend (to ram) instead. [09:07] He said that the only solution he found was to compile kernel. No idea really what he was looking for. Was mentioning having to resize swap and so on. [09:08] And to be honest that's really outside of capabilities of normal everyday user. [09:09] iirc, hibernation is enabled for certified systems, while on others, you have to enable it yourself and pray it works [09:09] Furai: what works well anhd what does not is still very dependant on hardware (part) manufacturers interest in supporting and testing linux. and while your brothers' experience seems worse than the average - there can be things which need some manual tweaking. [09:09] "certified systems" ? [09:10] tomreyn, yes, he's aware of that.

[09:11] And how regular user is even supposed to find those articles? [09:11] I've been on Freenode for years. I know I can usually just ask question and find my answers. [09:12] Searching the net for someone inexperienced might be futile or lead to documents that are hard to follow or risk losing data if done wrong. [09:12] Anyway, enough /rant. [09:13] we can always discuss in #ubuntu-discuss [09:13] We all know how the things are. And whining about won't fix things.

There is no selection like Configure ISCSI volumes ? I need help [12:04] gokhani: welcome, you might have more luck in #ubuntu-server for that [12:05] ok thanks lotuspsychje [12:15] FreeBDSM: it's talking about the old days when switching between X and VCs were slow because the kernel wasn't in charge of modesetting, so there was a long pause where control switched from the X driver to the kernel and vice-versa. [12:16] FreeBDSM: afaik you can still see this with some drivers like the nvidia driver, which still lacks KMS afaik. [12:17] FreeBDSM: nowadays the switch is nearly instantaneous for all effective purposes. [12:17] though there's still a very brief pause. [12:18] ryuo: well, it takes 1-2 sec for me [12:18] even more like 3 [12:19] and yes, nvidia driver here [12:19] ok, well that probably explains it. [12:19] KMS is primarily for the open source drivers. [12:20] Intel / Radeon being the primary users. [12:20] but I've enabled nvidia nvidia_modeset nvidia_uvm nvidia_drm in initramfs and following https://wiki.archlinux.org/index.php/NVIDIA#DRM_kernel_mode_setting added `nvidia-drm.modeset=1` kernel param to grub [12:21] archwiki says 'nvidia 364.16 adds support for DRM (Direct Rendering Manager) kernel mode setting' [12:21] Do you have a new enough version? [12:22] weird that I have nvidia-compute-utils-415, nvidia-dkms-415 and nvidia-kernel-common-415, the rest of the packages are -430 [12:22] ah, they have status 'rc', not 'ii' [12:23] ok.. are you sure you bundled the kernel modules in the initramfs? ARCH uses a different system. [12:24] theirs is called mkinitcpio. [12:24] changes to grub also necessitate regenerating the config. [12:24] tomreyn: Allright, how do how do enable the HWE kernel?, iI notice its running the generic kernel [12:24] tomreyn: Ill get back to you with this tonight :) [12:25] !hwe | LaserAllan_ [12:25] LaserAllan_: The Ubuntu LTS enablement stacks provide newer kernel and X support for existing LTS releases, see https://wiki.ubuntu.com/Kernel/LTSEnablementStack [12:26] tomreyn: oh, so its that imple [12:26] I will give that a go [12:26] I also read somwhere that i can try to update the Intel drivers [12:27] LaserAllan_: you did so by using the PPA. but you should probably not mix the PPAs with HWE [12:27] tomreyn: Allright I will try HWE first then [12:27] LaserAllan_: and first of all, again, review your logs with the standard or HWE kernel. [12:28] should it be as simple as veryfying if it has changed after installing the HWE kernel then? [12:28] Hopefully that solves it [12:29] I am also not sure that HDMI cna push 5120x1440 [12:31] hmm me neither, that's something you should probably read up on, too [12:32] tomreyn: so far I haven't really read any issues [12:33] tomreyn: but windows can push 5120x1440 SO, there is no doubt that USB-C can do that....I haven't tried this with HDMI. But I will start to install the HWE kernel when i get home [12:33] Hopefuly that helps [12:33] https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video says hdmi 2.1 supports 5120 x 2880 (5K) [12:33] I will report back :) [12:33] tomreyn: I am not sur eif my laptop (Lenovo T480) has HDMI 2.1 [12:34] you will see [12:36] Yup [12:36] I iwll however install HWE Kernel tonight and we'll see how it all goes [13:20] mystery solved [13:20] I've got a problem. there is somewhere a trigger in my system (desktop, xfce, 16.04) that let crackle my audio periodically and if xfce4-volumed is active the osd volume appears then. what could it be? this behaviour appeared the first time as I pressed the volume up or down on my old keyboard but it happens with my new keyboard too [13:20] the usb stick was just a microcontroller meant to use the windows key + r to run a web browser and launch a site [13:24] hi, everyone, I just did `sudo apt upgrade` today and it upgrades firefox. [13:25] However after the upgrade, I cannot switch input method as I did before. [13:25] In the text field of a website, I cannot switch input method. [13:25] I used to use super+space to switch input method. [13:26] I can still switch when the cursor is on the address bar or search bar. [13:26] but not on the text field inside a website. [13:27] I tried several things. One thing I found out is that if I press super+space super+space twice, I can switch. [13:27] ryuo: I did add those 3 modules to `/etc/initramfs-tools/modules`, then did `sudo update-initramfs -k $(uname -r) -c`, then added `nvidia-drm.modeset=1` kernelparm to grub and did `sudo update-grub` [13:28] leeijaw: is that only affecting Firefox? Which firefox version/package? which ubuntu release? [13:28] Or super+c super+space also works, but super+space alone no longer works. [13:28] Yep only firefox [13:28] firefox/bionic-updates,bionic-security,now 68.0+build3-0ubuntu0.18.04.1 [13:29] firefox:amd64 (67.0.4+build1-0ubuntu0.18.04.1, 68.0+build3-0ubuntu0.18.04.1) [13:29] At least, the previous version doesn't have the problem. [13:30] TJ-: [13:31] I guess it has to be related to the super key. [13:31] I'll to bind the action to another hotkey and see if the problem persists. [13:32] [drm] [nvidia-drm] [GPU ID 0x00000100] Loading driver; resource sanity check: requesting [mem 0x000e0000-0x000fffff], which spans more than PCI Bus 0000:00 [mem 0x000e0000-0x000e3fff window]; caller os_map_kernel_space.part.9+0x6d/0x80 [nvidia] mapping multiple BARs - what do these mean (from dmesg)? [13:32] leeijaw: I'm on the same versions here and Super+Space works correctly (I tested in the DuckDuckGo search box) [13:33] TJ-: I tried to bind it to ctrl-space, it works but not super+space [13:33] leeijaw: is something else grabbing the Super key I wonder? [13:33] TJ-: I am using fcitx, what input method framework are you using? [13:34] leeijaw: ibus [13:34] ⛐ [13:34] yes, and it works here ^^^ emoji method [13:34] ibus has always been working very wel with the rest of the system but its functionality is limited. [13:35] Mine is fcitx, it only has the problem on firefox website text field but not on any other software I found so far. [13:35] I even tried Google Chrome, it works. Only firefox exhibits this problem. [13:36] leeijaw: is it any web-site or just a few you've tested? [13:36] leeijaw: does it fail on paste.ubuntu.com for example? [13:37] I tried google, baidu, wikipedia, and many others. [13:37] I'll try it. [13:38] TJ-: Yes, it fails as long as it is inside the web page. === jmcgnh_ is now known as jmcgnh [13:43] leeijaw: not sure what is going on there. Try creating a new user account and testing from that - that will help determine if it is a per-user issue, or system-wide [13:43] TJ-: I could work around this problem by binding the hotkey to ctrl-space, but I am a heavy Emacs user, and C-SPC is a really important key in Emacs. Maybe I could just get used to press super-space twice to switch input method, a little inconvenience though. [13:45] leeijaw: if it works when you press it twice, that's like in nested tmux having to do Ctrl+B, Ctrl+B -- is there a Firefox addon that is handling Super+Space... have you tested Firefox in Safe mode? [13:46] I'll try safe mode first and then another user account next. [13:48] Safe mode doesn't work. [13:55] leeijaw: have you installed any other software or made config changes recently that could be related? [13:55] All I did was `sudo apt upgrade` [13:55] I suggest you do apt full-upgrade [13:55] I didn't install any new software or addon. [13:59] cfhowlett: The output of `full-upgrade` is the same as plain `upgrade`. [14:02] leeijaw: silly question but, if you had both fcitx and ibus were enabled, could they both be trying to consume super+space (I know in ibus it can be set on a per-application basis) [14:19] leeijaw, if the problem is FF, i'd try a 'refresh' [14:20] TJ-: The funny I found out is that after I created new account, I cannot even get fcitx working. [14:21] leeijaw: time to kick the machine :D [14:22] I upgrade my computer from 16.04 January this year, and all the configuration is migrated from the previous release. Maybe fcitx doesn't work well with gnome 3, the new desktop environment for 18. [14:22] leeijaw: I've not used Gnome for 10 years so wouldn't surprise me [14:24] Maybe I need to reconfigure the fcitx from scratch and see if this is also a problem with my installation of fcitx. [14:30] leeijaw, baidu? [14:34] cfhowlett: yep, I use bing and baidu as my secondary search engine. [14:34] !kylin | leeijaw guessing from that info and you nick that you're Chinese. Seen this? [14:34] leeijaw guessing from that info and you nick that you're Chinese. Seen this?: Ubuntu Kylin is a variant of Ubuntu that focuses on Chinese users. It is an official part of Ubuntu. For more information, see http://www.ubuntukylin.com/ [14:35] might be worth testing to get past your current problem [14:36] Ah, I am interested in plain Ubuntu and set it up to my liking. [14:36] more interested [14:36] fair enough [14:38] leeijaw, you said 18.04 yes? [14:38] https://www.pinyinjoe.com/linux/ubuntu-18-gnome-chinese-setup.htm [14:39] Yes, 18.04. I upgraded my PC from 16.04 to 18.04 this Jan. [14:40] I waited for one year to move and hope everything will be smoother a year later. [14:40] very wise. [14:52] Ubuntu has built-in features to automatically check my email and just let me know I have new (including sender and subject)? [14:55] rapidwave: Typically if you are using an e-mail client like Thunderbird, it will trigger a toaster notification when new messages arrive. There might be an app that you can install that would handle just the notifications, but I'm not aware of any [15:25] TJ-: After several rebooting and experimenting with my new user account and also tried login with Unity, my conclusion is that this is due to poor integration of fcitx into the new Ubuntu desktop environment. Under Unity, I can set the keybinding using system setting. The fcitx configuration panel also has its own place to set the key. Under unity, I can set them to different keys and both of them worked well. Under the new desktop env [15:25] ironment, only the key set with fcitx configuration panel works and only if that key is different from the system key binding. In order to use super+space to switch input method under new desktop environment, I have to unset the system keybinding, and it works well on every software I installed, except on the webpage area (any site) of the newly upgraded firefox. [15:26] i'm running ubuntu 18.04.1 lts with the kernel 3.10.107. is there any repository providing the perf linux-tools for that kernel? i need the 'perf' module [15:27] tribly, why not 18.04.2? [15:28] I'm concerned by the really old kernel version [15:28] tribly, yeah, how did you get 3.10 on 18.04.1? The LTS kernel package? [15:29] using version provided by odroid. i'm using an odroid-c1+ [15:30] tribly, so, not actual Ubuntu. odroid's Ubuntu remix isn't supported here. [15:32] TJ-: Even under unity, I cannot switch input method using super-key smoothly on the new firefox. [15:33] lordcirth: so what would be the solution, if i weren't using odroid? [15:41] tribly, the solution would be "use a supported kernel". [15:44] that's not really a solution [15:45] Yes it is. [15:45] tribly: we only support, supported kernels here [15:46] Sometimes the answer is "don't do that". [15:46] i have to do that. so no, that's not a solution [15:47] tribly: The volunteers here are only able to support the officially release Ubuntu flavors and software found in the preinstalled repositories. There are many projects that base themselves off of Ubuntu, and those that do are responsible for providing their own support network. The volunteers here do not have the necessary documentation to support derivatives of Ubuntu. There are significant changes (as in your case a very old [15:47] kernel being supplied) that just isn't possible to support in this forum. [15:47] tribly, you have to do that because you are on odroid. If you were on Ubuntu, you presumably wouldn't need 3.10. [15:54] "presumably wouldn't", exactly. you don't know what i need, or why. but thanks for the 'help' [15:55] tribly: you're asking for support in #ubuntu when you're not running Ubuntu. You're running a fork of Ubuntu. Seek support from whoever forked and modified the OS. [15:56] tribly: you can build it yourself based on https://wiki.odroid.com/odroid-c1/os_images/ubuntu/v3.0 [15:59] Hello [15:59] hello, how can i start this in a systemctl on boot on ubuntu screen -dm -S minecraft /opt/minecraft/ServerStart.sh [16:00] p0a: welcome, what can we do for you? [16:00] for some reasons this needs root? or sudo user privs!? [16:00] I installed (apt-get) something from a custom sources.list file and then deleted the line to restore my sources.list. Now apt-get says the packages I installed are no longer needed. Did I make a mistake? [16:00] TJ-: https://github.com/LeeiFrankJaw/ConfRepo/blob/master/user-phrases.txt I used to maintain a personal phrase list for ibus, it was such a painful process. That was the reason I moved to fcitx. As an input method, IBus is way behind state of art tech, like IMEs from 90s, 00s at best. I might give it second try now and see if there is any improvements. [16:01] p0a: can you pastebin us your sources.list please? [16:01] lotuspsychje: it is the usual now [16:02] lotuspsychje: do you want to see the line I added? [16:02] lotuspsychje: deb https://crawl.develz.org/debian crawl 0.23 [16:08] !sources | p0a [16:08] p0a: The packages in Ubuntu are divided into several sections. More information at https://help.ubuntu.com/community/Repositories - See https://wiki.ubuntu.com/RecommendedSources for the recommended way to set up your repositories. [16:09] p0a: sometimes apt does autocleanup of packages that are not needed anymore, maybe its not related? [16:14] lotuspsychje: yeah! thank you [16:14] Surfer2011: can the section, create systemd file help? https://linuxize.com/post/how-to-install-minecraft-server-on-ubuntu-18-04/ [16:16] not sure ... because i have a ServerStart.sh script ... which is calling the jar file with java works perfectly [16:16] but 1.) i want to start it in a detatched screen so i can "log into the server console" without stopping and starting the server [16:16] and 2.) it seems like i need sudo privs if i own ALL the files in the minecraft dir by this so called minecraft user [16:17] so i now owned all by my system "root" user [16:17] Surfer2011, https://gist.github.com/justinjahn/4fe65b552b0622662420928cc8ffc7c0 [16:18] ioria: i saw this allready but it has some WorkingDirectory=/opt/minecraft/instances/%i for ? different servers in it which i don't need and can't get figured out how to remove it [16:18] and 2nd i have a bash script to start my server [16:19] Surfer2011, 1) you probabli can skip the wd 2) just replace the line with the script ? [16:20] not working because i supposingly does not find the jar file that is called by the script [16:20]
