[00:00] I get "can't find command 'geometry'". [00:00] hmm okay, maybe that's been removed since [00:01] stavrakis: but this really means that your system wont be able to boot directly off the sdcard and you need to load the initrd with all sdcard modules from emmc, then the kernel can be loaded from sdcard. [00:02] https://help.ubuntu.com/community/BootFromSD [00:03] tomreyn, so just put the kernel on the emmc? [00:04] stavrakis: initrd yes, the kernel can be on the sdcard (or on the emmc) === MedicalDebt is now known as X230t [00:12] I get gmon.out files in some of my directories for some reason. [00:15] tomreyn, since I don't really know what is put into the initrd for it to be ~50MB, is it possible to reduce the size by removing unnecessary modules and maybe using lzma instead of gzip? [00:20] hi [00:20] :) [00:20] I just installed weechat... testing out the IRC client [00:21] Awesome... [00:21] I like this [00:21] clear [00:26] Bashing-om: thanks!

[00:47] Is it ok if I put "apt autoremove" in root cron? [00:49] or, "can you think of any disasters that will result from this?" [00:51] energizer: Why ? as autoremove is available as a function of unattended-upgrades; Unattended-updates is triggered by a daily cronjob: /etc/cron.daily/apt-compat .

[00:58] Ubuntu is detecting my GPU (NVidia), but not any of the displays attached to it. [00:59] Any idea what the heck is going on here? [00:59] I go to "displays", but only the built-in VGA port shows up. [00:59] but the card is clearly detected when I "lspci". [01:00] (Ubuntu 16.04 LTS) for reference. [01:05] i have triple boot, lubuntu ubuntu and win, just made an dist-upgrade on the lubuntu and in grub i only get lubuntu, os-prober shows all 3, update-grub does not, what do i do? [01:21] firef1y: what's your setup? [01:24] skiboy: NVIDIA 1060 6GB, Supermicro X9DRI-LN4F+, dual Xeon E5-2670. [01:25] firef1y: what have you done so far, what drivers do you have installed, and are there any relevant logs that you can show us? [01:25] skiboy: nouveau drivers for now. (I'm operating on liveCD for now) What logs would you like to see. [01:26] firef1y: nouveau won't work [01:26] lspci shows the card as being there, xrandr shows nothing. [01:26] skiboy: why not? [01:27] firef1y: You need the closed-source drivers. Nouveau doesn't play nicely with the new cards that require signed firmware [01:29] firef1y: Nvidia is the only thing that has ever messed up my system. Nvidia problems are the least fun to deal with. I actually came into this channel 2 days ago for a login loop triggered by an Nvidia update [01:30] skiboy: okay, switching to binary drivers... [01:31] firef1y: I don't like it either, but we have to use their drivers if we want to use any of the new cards and get any functionality [01:32] firef1y: You're lucky you don't have to deal with Optimus [01:37] I'm surprised that it wouldn't even work on at least a VESA-level without the drivers... [01:40] firef1y: all I know is that nouveau has been having serious problems with the new cards [01:42] Hi, can someone point me in the right direction? I have an LVM volume mounted at / and it's space is full. on the same harddrive i still have 40g unpartitioned space. how do i add this unpartitioned space onto the lvm volume via command line?

[01:50] good question [01:50] i.e. do you have a single encrypted LV or are all LVs encrypted as a whole? [01:52] mhm [01:52] all done [01:53] the tutorial above worked [01:54] so dmcrypt-luks is below lvm [01:54] skiboy: I'm now fixing the 20 other issues that I found in the course of fixing the first one. [01:54] hopefully I'll get the drivers installed soon. [01:55] seems so tomeryn [01:55] just rebooted and all good [01:55] so i guess i'm good [01:55] thanks tho! [01:56] welcome [01:59] firef1y, skyboy: you could buy that other companies' hardware instead, who develop an open source driver for linux and whom torvalds has not had reason to raise his special finger for, yet. === JanC is now known as Guest74037 === JanC_ is now known as JanC [02:05] tomreyn: They aren't commonly used in laptops [02:06] tomreyn: besides, I need CUDA for Blender [02:12] tomreyn: One word: CUDA.

[02:36] dunpeal: The default firewall is iptables but it's not configured to do anything out of the box. You need to setup rules for it using something like ufw [02:39] Has anyone managed to get ad blocking using dbab and dnsmasq working on a standalone laptop? https://github.com/suntong/dbab [02:55] Thanks. [03:36] Hello. I've attached a Velleman K8055 USB I/O device to a Ubuntu 16.04 LTS 64-bit system.. and it works with libusb and libk8055 installed. [03:37] But using the k8055 utility puts an error message into syslog: usb 5-2: usbfs: interface 0 claimed by usbfs while 'k8055' sets config #1 [03:38] Could someone offer a ..clue.. as to how to get rid of that message? [03:47] hello, my wireless mouse freezes for half second every 2 seconds more or less after systems recovers from sleep. I suspect from TLP maybe not sure [03:47] batteries? [03:47] cable is plugged [03:47] ah sorry [03:48] it got new batteries even rechargable batteries [03:48] i wonder what i can do debug this [04:03] any idea? [04:04] i just noticed that is i disconnect the mouse transmitter put the laptop to sleep, wake it up and connect the mouse it works fine again [04:10] enav: Any relevant looking messages in dmesg? [04:11] i have no idea what dmesg is [04:13] enav: "dmesg" prints the messages from the kernel's ring buffer, which gives you verbose information about events happening in the kernel and often has useful information when debugging hardware problems. [04:13] shall i run that command on CLI ? [04:14] enav: Please run "dmesg" in a terminal and post the output it produces to http://pastebin.ubuntu.com then post the link to the output here. [04:14] mouse is working fine right now [04:14] let me put the laptop to sleep and wake it up to recreate the issue [04:14] brb [04:18] http://dpaste.com/3NZ6H92.txt [04:18] i copied the bits with red text that seems to be errors [04:20] now im supper sure it is TLP [04:21] started TLP, put the laptop to sleep and then wakeup, now the mouse works at interval [04:21] intervals * [04:22] enav: TLP? [04:22] yah TLP this popular battery saving utility [04:23] enav: Do you have this problem when TLP is not running? [04:23] im not [04:23] seems like TLP turn off the USB ports at short interval [04:24] but happens only after wakeup [04:24] if i pkill tlp and wake the laptop the issue goes away [04:32] just removed tlp and problem is solved [04:32] thanks for the help anyways [04:45] Hello everyone.

I have checked routes, which cannot [04:50] be the reason, as both the native ipv6 and tunnel ipv6 have different interfaces.

[07:34] % of cpu [07:34] like i have folder call program [07:34] http://blog.scoutapp.com/articles/2014/11/04/restricting-process-cpu-usage-using-nice-cpulimit-and-cgroups [07:35] in that folder i have c++ program so want that program to use equal to or less then % of cpu === r0Oter is now known as r00ter [07:49] not working [07:55] how to kill all process [07:55] cool_dude: you don't kill all processes [07:55] cool_dude: what are you actually trying to achieve here [07:55] perticular [07:55] i have pid [07:55] what ? [07:55] process id [07:55] how do you want to kill it, [07:55] the kill command responds to PID [08:00] My system get an Kernel panic - not syncing: Out of memory and no killable processes after few hours. It's Lubuntu 17.10 with 2 GB ram and 8 GB swap file. Any solutions? [08:00] sounds like you're just out of ram [08:01] I suspect something is eating it up quickly and swap is trying to keep it alive until there is nothing left [08:01] do i need a bigger swap? [08:01] opencw: use "top" or similar program to track what programs are using memory. You can also use "free" to check memory usage over time. [08:01] opencw: no [08:01] opencw: if you run out of 8GB swap with 2GB RAM then something is seriously wrong. [08:02] opencw: find out what's using that memory and if that is normal for that process. [08:02] ok [08:02] 2GB is just too low for most things [08:03] it has only a emmc flash as drive [08:03] Ben64: well, sure, but we should figure out what the probem is before he goes out and buys more RAM (if his platform is even expandable) [08:04] no can't upgrade :-) [08:04] opencw: if you run things on it that means you use swap a lot, then you're most likely going to kill that emmc flash drive in short time. [08:04] it's an ultrabook [08:04] oh, ok [08:11] when use cpulimit command it stucks at like Process 25928 detected [08:12] does it take time to cpu limit [08:12] ? [08:12] cool_dude: what exactly are you trying to do ? [08:12] i want to limit process [08:12] hello all. my mysql server won't start anymore. all i get is some mysterious apparmor denied messages. can anyone help? [08:12] cool_dude: why ? [08:13] because it uses 100% cpu [08:13] cool_dude: what is the process ? [08:13] md5sum /dev/zero & [08:13] cool_dude: grow up [08:13] cool_dude: what do you think that is going to do [08:14] i didn’t understand [08:14] why are you running a checksum of /dev/zero and backgrounding it [08:14] that is example process [08:14] cool_dude: Please stop trolling. This is a support channel [08:14] what is the REAL problem [08:14] cool_dude: give us the real problem, not an exmple [08:15] cool_dude: if you want to limit processes, use cgroups [08:15] cgroups not working on ubuntu [08:15] cgroups is what i most like [08:15] cool_dude: what is the process you are trying to limit [08:16] actually, forget it, I'm not interested [08:16] just giving command will help you [08:16] to understand [08:16] you gave an incorrect example [08:16] I asked for the real problem [08:16] or real context [08:16] ./xmr-stak-cpu [08:16] I'm not intersted [08:16] use 100% of cpu [08:17] i want to limit it to use 50% [08:17] this is the real problem [08:17] when try cpulimit it stopped at Process 25928 detected [08:18] nice also didn’t work [08:18] and when i tried to install cgroups using apt-get install it says no packages [08:19] that’s all now who can help me ? [08:22] can someone explain to me why apparmor suddenly denies to start the mysql server? [08:22] suddenly ? [08:23] yeah ... yesterday everything was running smoothly [08:24] so what have you done to the system since it was last started ? [08:24] i have done nothing. that's why i call it mysterious! [08:25] what seems unlikely [08:25] i can't find any problems in the logs [08:25] why does apparmor say it's blocking it [08:25] ok i changed the fstab for some smb-mounts .. i remember ... but that has nothing to do with the mysql server [08:26] wait ... i will paste the error message [08:26] so you have changed things [08:26] what else [08:27] https://paste.ubuntu.com/25842793/ [08:27] that is everything. really [08:28] mysql community server [08:28] is that the version that ships with ubuntu ? or from an external repo [08:28] it is the package you get when installing mysql-server [08:29] so it is from the repo [08:29] never seen it referenced as community [08:29] there are no third party repos active [08:29] where is your mysql data stored ? [08:30] i did not change any storage locations on the mysql server [08:30] where is your mysql data stored ? [08:30] so probably the default location /var/lib/mysql/ i guess [08:31] yeah ... just checked [08:31] run the apparmor error explain plan against the mysql profile [08:31] how do i do this? [08:32] not got apparmor here, hang on, I'll have to check the docs [08:32] (have you checked the apparmor docs) [08:32] i tried understanding apparmor ... but it is a little cryptic to me to be honest [08:33] why are you using it then ? [08:33] just disable it [08:33] it's there by default ... and probably with a good reason i guess [08:33] not if you don't know how to use / interact with it [08:33] well you might be right [08:34] mysql looks like it's trying to access proc [08:34] look in the apparmor profile in /etc/apparmor.d and see if the mysql policy allows that [08:37] the file usr.sbin.mysqld does not contain anything with /proc as far as i can see [08:38] udzguru: so that may explain why it's being a problem [08:38] udzguru: have you had any updates applied to the host ? [08:38] the system is up-to-date [08:39] and i did not change anything regarding the apparmor profile manually. [08:39] i looked at the file for the first time today [08:40] udzguru: it's up to date....when did you apply updates [08:40] i do that everyday. so yesterday afternoon. [08:40] so when I asked "what's changed" and you said "nothing" [08:41] there were no updates available [08:41] you've a.) changed fstab b.) applied updates [08:41] so ... no changes since then [08:41] when did you APPLY updates [08:41] that means updates happened [08:41] i think thursday ... there was an update for systemd if i remember correctly [08:42] i just run sudo apt-get update && sudo apt-get dist-upgrade daily [08:42] ikonia thanks for so called help [08:42] yesterday in the evening the server was running just fine. [08:42] but that really worked [08:46] cool_dude: cgroups is a kernel feature, not a package [08:46] cool_dude: apt search cgroups [08:46] but i have to dl cgroups-tools [08:46] cool_dude: yes [08:47] cool_dude: and the cgroups daemon [08:47] i haven’t did that [08:48] necessary ? [08:48] cool_dude: I told you I wasn't interested, dont be sarcastic [08:48] Question : I am using ubuntu 14.04 as kvm guest, The interface is having static ipv4/ipv6 and works very well with virtio support, The problem is i am using ipv6 tunnel as well, when i make my tunnel up, the native ipv6 which is configured on eth0, stops working, ipv4 on eth0 is working fine, and if i make the other tunnel down, the native again start working.

[08:50] thanks skiboy [08:51] udzguru: thats why I asked about updates [08:51] let me think ... is there a way to see which updates have been installed lately? [08:52] there is a apt history command [08:56] these were the last updates that were installed on 2017-10-27: https://paste.ubuntu.com/25842908/ [08:57] so i was right there was an update to systemd [08:57] something has changed then [08:58] but either way you have a choice of updating the profile or disabling apparmor [08:59] ok ... is there any guided way to update such a profile? i already googled for reprofile or reconfigure [08:59] so you need to add "read" permissoins to /proc looking at your output [08:59] so you need something like r /proc/ in the mysql profile [08:59] and i also found out that there is a enforced mode (which mysql seems to be in) and a complain mode [09:00] thats pretty much what it says on the tin, enforce it, or warn about it [09:02] i will try to add read to /proc ... gimme a sec [09:13] hi there [09:16] is there a way to slowdown networkmanager at startup ? [09:17] ikonia, i reprofiled now ... there are no more apparmor errors. but mysql still does not want to come up :( [09:18] unimatrix9: why? [09:20] booting from ssd is so fast that it alway's struggles with wifi === Jochen_wvdT is now known as Schlawiner [09:21] then i have to reset network manager to get it running [09:21] unimatrix9: struggles how? [09:21] cant get it up and fails , sometime, not alway's [09:21] unimatrix9: put a reset network manager that runs later [09:22] hmm, reset script in sessions , something like that ? [09:23] would be nicer to just slow the startup of the networkmanager a bit.. [09:24] unimatrix9: i'm not sure how that'd affect other stuff, try first "sudo crontab -e" and add the line @reboot systemctl restart networkmanager [09:24] unimatrix9: which ubuntu version is it? [09:24] udzguru: what does the error state now [09:24] udzguru: (nice job updating the profile too) [09:25] 1604.3 lts [09:25] unimatrix9: ok use that command [09:26] ikonia, https://paste.ubuntu.com/25843022/ [09:26] that's in the syslog [09:27] ok thanks [09:27] i am currently checking the systemd mysql service file [09:27] unimatrix9: no problem [09:27] * unimatrix9 afk [09:28] everything there seems to be fine as far as i can tell [09:29] udzguru: it seems someone has changed your system [09:29] udzguru: as the startup argument AND apparmor dont just get changed on their own [09:30] udzguru: get the systemd startup output too [09:30] that would be journalctl? [09:31] yup [09:32] https://paste.ubuntu.com/25843049/ [09:32] nothing obvious i would say [09:33] the INVALIDARGUMENT part irritates me [09:34] udzguru: always try starting it manually [09:40] i will be back ;) [09:40] ikonia, i was just disconnected. sorry. === KindTwo is now known as KindOne [09:41] unimatrix9: ok [09:43] Can I splitscreen applications in lubuntu?

[09:50] manually starting the mysql server just brings the same results [09:51] and systemd seems to be continually trying to start mysql and fails. [10:01] since upgrade, I can't use windows key for copy/paste/etc when I am remote controlling clients (super-C super-V D:). is there a way to turn off the gnome desktop keybinds when a specific program has focus? [10:01] it worked in unity [10:01] I could have sworn there was something in ccsm but I can't find it anymore [10:02] rules or something [10:03] oh, I meant mac clients, and their ridiculous option key which is super on my end [10:05] gnome seems to entirely take over the super key, not passing it through to the program if it doesn't recognize the combination, which is ridiculous [10:06] doug16k, are you on 17.10 [10:07] yes [10:07] doug16k, have you added extensions from the gnome extensions site [10:07] no, it is all defaults [10:07] doug16k, you might wish to check there for something more suitable to you [10:12] hello gius [10:12] *guys [10:12] systemd sometimes frustrates me ... [10:13] If I update ubuntu 16.04 to 17.10, my understanding is that I have to update first to 17.04. Will this install unity 8 to my system? [10:14] I don't really want to put unity 8 in my system, I would like to avoid it. any thoughts? Thanks a lot in advance :) [10:14] billythekido: you need 16.10, then 17.04, then 17.10 [10:15] And 2 of them are unsupported [10:15] Unity 8...? Do you mean gnome, that 17.10 uses? [10:16] @alkig kalimera [10:16] kalimera :) [10:16] I want to move to gnome. The intermediate version had unity 8. [10:16] No Ubuntu shipped with unity 8 [10:16] Unity 7? [10:16] What's the output of `ls /usr/share/xsessions` on your system? [10:17] I'm defintitely on unity 7 [10:17] I thought one of the intermediate versions had 8 [10:17] so I guess I got my answer :) [10:17] No, 8 was never production quality [10:17] Only alpha [10:17] hehehe. thanks a lot mate :) [10:17] np [10:17] did u upgrade by any chance? [10:17] I'm using MATE [10:18] oh ok :) [10:18] I tested Gnomein 17.10 though [10:18] me too [10:18] on a VM [10:18] it's reasonably stable [10:19] I'm off to upgrade the system. euxaristo poli! [10:19] bb [10:22] * alkisg wonders if do-release-upgrade actually works for unsupported releases like 16.04 => 16.10 => 17.04 => 17.10... [10:22] Upgrading _from_ an unsupported release sounds fine, pointing to archives, but _to_ an unsupported release... [10:28] my mysql server won't start. anyone willing to take a look into this with me? [10:28] udzguru: not getting anywhere ? [10:29] nowhere. [10:29] what issue are you getting udzguru and how are you trying to start it [10:29] i'm trying to start it with systemd [10:29] have you checked the unit file exists [10:29] eb0t: what ?? [10:29] jeah it exits [10:30] exists [10:30] ah ok...what error is it throwing [10:30] udzguru: share where you're up to and the current issue [10:30] ikonia what do you want to know [10:30] eb0t: the problem [10:30] well i dont know it yet .. [10:31] eb0t: right, so telling him to randomly check files seems foolish [10:31] until you actually know the problem [10:31] nothing random about anything i have said [10:31] i haven't made any progress ... still trying to start the mysql server via sudo service mysql start gets me this https://paste.ubuntu.com/25843049/ [10:31] hello? [10:31] i approach every issue from the beginning [10:31] from start to finish [10:31] nothing random [10:31] it is random [10:31] checking if files exist [10:31] random to someone who hasnt got a clue what is going on maybe [10:32] and systemd seems to be continually trying to start the server (when i tail syslog i see the same errors all the time) [10:32] when you have no details of the problem [10:32] eb0t: why didn't you check what user he was trying to start it as, check if his shell was valid, they are equally as valid and random [10:33] keyboard shortcuts in qt programs don't work either in gnome. if the OK button has the O underlined, alt+o won't trigger the button. worked in unity :( [10:33] mysqld --help [10:33] run that udzguru and see what error it throws [10:33] eb0t: that won't show you the error [10:33]
