[00:00] Does anyone have an idea why Ubuntu is sticking with GCC 5, even with Artful? [00:01] Seems odd to continue to use that version [00:01] oh wait, default gcc is 7, but they also have 4 and 5 packages [00:01] nevermind [00:09] Question: I am installing Ubuntu in BIOS (legacy mode). My first partition is 550MB and I marked it as "Reserved BIOS boot area". No I need to have a "bootable" flag "On" for this partiton? Yes I know for BIOS bios grub 550MB is more than enough, but I kept it at 550MB becasue I plan on migrating to EFI in the future. [00:16] Zythyr: for BIOS Boot you only need at most 2MB :) [00:17] Zythyr: and no it doesn't need a bootable flag, in fact, with GPT, there is no such thing although if you're creating a hybrid MBR that also maps that partition then the MBR can have it's boot flag set [00:17] TJ- Im doing BIOS with GPT partition scheme. In Gparted, My first partition is 550MB and I put "bios_grub" flag on it. But before installing Ubunut, its asking me if I want to put "bootable" flag on it. I did 550MB because in the future I will be doing EFI instead of BIOS [00:17] Zythyr: if you can plan on having EFI later, then just create both an EFI System Partition of about 512MB and a 2MB BIOS Boot partition [00:18] Ohh okay. So if I am doing GPT then bootable flag not need [00:18] So the 2MB boot partition needs to be before the EFI System Partition? [00:18] Zythyr: here's what I use: https://paste.ubuntu.com/26486498/ [00:19] Zythyr: as long as the BIOS Boot partition is near the start of the disk the order doesn't matter [00:26] TJ- Thanks for the share. I did similar but I didn't create teh "BIOS boot partition" of 8MB. I created a 550MB partition and called it "EFI System System" even though I am using it as BIOS boot partition. Is that fine? [00:27] Zythyr: well it means you can only do either/or. With my way you can do both and so choose which mode to boot in [00:28] Ohh I didn't know both options were possible. I already started install of Ubuntu server. Is it possible to fix it after installation? [00:28] whats the purpose of encrypting my home folder [00:29] if i want more security i should encrypt / too ? [00:29] And when you say choose either/or, how do you choose if u want to BIOS or EFI method of booting? [00:29] Zythyr: all you need to do is partition it so both partitions are there; you can do the additional GRUB work later to have both types of boot available [00:30] dingir: encrypted home means that even if the PC is booted, your personal files cannot be read unless your user is logged in [00:30] dingir: whereas Full Disk Encryption protects the complete OS when it's NOT running (e.g. if the system/disk were stolen) [00:31] hi [00:31] dingir Encryption is good if you don't want anyone with physical access to your hard drive to be able to read your data. For example, if your PC gets stolen, even though you may have a strong login password, the theif can use a live USB and read your data [00:32] TJ- Is your system configured so it automatically detects if your PC supports EFI boothing and if it then it boots to EFI and if not then BIOS? [00:32] hello everyone, ive recently updated my ubuntu 16.04 lts using a nvidia gpu (laptop), but i got some problem trying to reboot and im unable to see my system GUI, right now im on recovery mode, the error is "bbswitch not suitable _DMS call found [00:32] " [00:32] wth is that how to get the gui back? [00:33] Zythyr: no, it's configured so I can choose at boot-time, in the firmware's boot menu, which type of boot I want [00:33] and my connectyion sucks [00:34] mattfly: is this of any help? https://askubuntu.com/questions/857816/my-drivers-recognize-my-graphics-card-but-nvidia-settings-do-not [00:34] How do people update things like quagga that pop up a dialogue asking about restarting a daemon using things like ansible? [00:35] ok [00:36] but if only /home is encrypted its secure too if hard drive gets stolen as in no one can read the data [00:36] can i encrypt /home if system already installed? [00:37] mattfly: also this ubuntu forums post about 16.04 and kernel upgrades seems more relevant. Try booting to an earlier kernel version via the GRUB boot menu > Advanced sub-menu. https://ubuntuforums.org/showthread.php?t=2372056 [00:37] anyone can check please qdbus org.mpris.clementine [00:38] Service 'org.mpris.clementine' does not exist.Why ? [00:38] dingir: it's not /home/ that is encrypted, it's /home/$USER/ and yes, it's also protected if the device is stolen. It doesn't protect against someone being able to insert malware if they have physical access to the powered-off PC though [00:41] dingir I recently researched about encryption. I dected to encrypt my entire home partition instead of just /home/myusername. These two articles will be a good read for you 1) https://wiki.archlinux.org/index.php/Disk_encryption and 2) https://help.ubuntu.com/community/ManualFullSystemEncryption [00:42] ^ the second article if for block device encryption compared to this artcile which is just to encrypt your /home/userusername folder 3) https://www.howtogeek.com/116032/how-to-encrypt-your-home-folder-after-installing-ubuntu/ [00:46] Hi there, I was wondering if anyone else has had success getting Ubuntu running on a MacBook Pro Mid-2015, and if they have seen any major performance degradations [00:47] TJ- When you say firmware's boot menu, you mean like the BIOS menu if u want to boot in UEFI mode or Legacy mode? [00:49] Zythyr: if it's using EFI then it's not BIOS :) BIOS and UEFI are firmware, UEFI manual boot menu usually offers the option to boot in UEFI mode via entries in the firmware's own memory, or via Compatibility Support Module (CSM) in BIOS mode for a specific device. [00:49] TJ- Ubuntu server is asking me if I want to install GRUB boot loader. Do I choose "/dev/sda" or do I choose "/dev/sda1"? Assuming my configuration was like yours where my sda1 was BIOS boot partiiton and sda2 EFI, then what would I choose? [00:50] Zythyr: /dev/sda [00:50] Zythyr, Grub always goes on the drive [00:50] Zythyr: GRUB figures out where to put it's core image and boot files, and write it's own config [00:51] !mactel | Guest65 [00:51] So always choose the drive? Not the partition (ex: sda1) [00:51] !mac | Guest65 [00:51] Guest65: For help on installing and using Ubuntu on a Mac, see: https://wiki.ubuntu.com/MactelSupportTeam/CommunityHelpPages [00:51] Zythyr: yes [00:51] Zythyr: unless you're doing something /very/ special and experimental [00:52] ohh okay [00:52] thanks ubottu [00:54] TJ- If I configure my partitions like yours, do I still mark sda1 (BIOS) as "bios_grub" partition in Gparted? And during installation mark it as "Reserved for BIOS boot"? As for the EFI partition, I won't be able to mark it for "EFI" becasue my system doens't hhave EFI so ubuntu doesn't even give me option to mark it [00:55] Zythyr: Yes, mark sda1 as bios_grub ... create the EFI SP as any other type - the only important part is to reserve the space. Once the OS is installed and booted you can change the partition type [00:57] Ohh okay. And the sda1 partition will be "unformatted" right? And the EFI parittio nas Fat32? Once I am done with installation of Ubuntu, I can mark the EFI partition as EFI? But do I need to do some configurations of grub after this? [00:57] Zythyr: yes, sda1 is unformatted. GRUB writes it's core image directly into that partition using grub-install [00:58] Ohh okay great! THanks for the clearifcation. [00:59] I think I am going to scratch the current install and restart. [00:59] and do the partition scheme like yours [01:01] Zythyr: after installing/booting in BIOS mode there is a bit of a dance to do to install the grub-efi - The way I do it is create a Virtual Machine that boots in EFI mode, attach the real hard disk to it as (/dev/sda) and a VM disk image file (e.g. /home/tj/diskimage.bin ), attach the installer ISO image as a DVD device to the VM, and boot. During EFI install I install the OS to the disk-image file but set === Fireman_Ed is now known as FiremanEd [01:01] the boot-loader device to /dev/sda so it uses the EFI system partition. [01:02] Ahh so u trick it into installing grub on /dev/sda [01:02] Cool [01:02] Good to know that [01:03] I think for now I will have partition scheme like your, but not touch the EFI System Partition. If an when I move to a system that is UEFI based, then I will worry about fixing the EFI system partition. But for now I will have the partition there as making it future proof [01:04] Zythyr: I then shutdown the VM, delete the disk-image file, mount the EFI SP into the current running OS ("mkdir -p /boot/grub/efi; mount /dev/sda2 /boot/grub/efi") and copy the grubx64.efi to the EFI removable media path so I can boot in EFI mode without an entry in the firmware's boot menu (EFI boot via the device name) with "cp /boot/grub/efi/EFI/ubuntu/grubx64.efi /boot/grub/efi/EFI/boot/bootx64.efi" [01:05] Zythyr: finally!! once rebooted in EFI mode, I just run "sudo grub-install /dev/sda" and it redoes the install but also calls efibootmgr to add Ubuntu to the firmware's boot menu [01:06] Zythyr: in reality, I pull a lot of tricks and don't do it that way, but I'm a GRUB hacker so I know how to short-circuit things, but if I told you that process you'd get hopelessly lost :) [01:10] hi [01:11] Linux kernel Version 4.4.0-111.134~14.04.1: contains a truckload of changes related to "speculative execution" Does this boot or even run ? [01:12] TJ- hahha thanks for the clearification after the VM install trick. Or else I would have been lost lol [01:13] TJ- Here is my setup. Apparently in Gparted I had the ESP option. I am unsure what will happen when I do Ubuntu Server install and when it installs GRUB. Maybe it will configure for both BIOS and EFI??? https://imgur.com/a/i2GGc [01:17] Zythyr: installer will only install GRUB in the same mode the installer booted in. So if installer starts from EFI mode it'll install grub-efi in EFI SP,if booted in BIOS/CSM mode it'll install grub-pc to the BIOS Boot partition [01:17] Zythyr: this is why we have to 'dance' to do both [01:18] ahhh now i understand what u mean [01:21] The problem is, if booted in EFI mode we /could/ install for both EFI and BIOS mode, but if booted in BIOS mode there's no access to the EFI variables so we cannot install an EFI boot menu entry, which means there'd be no access to the installed OS on reboot [01:27] Does anyone know of an XPath visualiser for linux? SOmething like XMLQuire? [01:29] well seems to boot and run all right : Linux acer30u 4.4.0-111-generic #134~14.04.1-Ubuntu SMP Mon Jan 15 15:39:56 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux === hidari is now known as nicedreams [01:38] TJ- if booted in EFI mode, how do I install for both EFI and BIOS? The reason I ask is becasue I can attached the HDD to a PC that boots into EFI mode and then do Ubuntu install from there [01:39] looks like a very nasty job nicely done : https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown [01:43] Zythyr: you'd install in just EFI mode as usual (with the EFI SP and BIOS Boot partitions), reboot into the OS, then do some clever stuff with installing the grub-pc-bin/grub2-common/grub-common but *NOT* the grub-pc package (because grub-pc would cause grub-efi and the other grub-efi-x86_64* packages to be removed) [01:44] Zythyr: there's a better way than that though, which is to create an LXD container with /dev/sda mapped into it and install just the grub-pc package. [01:45] Zythyr: I really ought to write-up all these methods because they look much simpler when you see just the commands without the long-winded explanation [01:46] any caveats to find -exec sed that works from the command line but not in a script? [01:47] where can one find /proc/config.gz on Ubuntu 14.04.5 LTS [01:49] ah less /boot/config-`uname -r` [01:49] weaksauce: shell expansions of variables, paths, maybe? [01:50] TJ- Ohhh so its not that simple even when booted into EFI mode. lol [01:50] That a write up tutorial somewhere would be great [01:50] TJ- https://gist.github.com/anonymous/ebf243c44800342653838e15591400d0 [01:51] SUB is printing out what I expect [01:51] Zythyr: I have a guide to the boot process itself here: http://iam.tj/prototype/guides/boot/ [01:52] i have taken off the exec portion and it's listing all the files that I expect it to see [01:52] stock@acer30u:~$ dmesg | grep -i isolation [01:52] [ 0.000000] Kernel/User page tables isolation: enabled [01:52] allright ave a good one [01:53] Hey guys. Hitting an issue today on 14.04 LTS (using for legacy software support). The issue comes up when a python (2.7) portion of a script is writing to disk. It's somewhere between blitz++, python2, and mpirun. I'm not able to reproduce outside of this program right now. Apt update history shows nothing changed since last known working run of this program. [01:53] weaksauce: does ./test exist for find in the script to find ? [01:53] it does TJ- [01:54] weaksauce: so is the issue all those logical-ORs because that's very different from the single shell command above [01:55] weaksauce: think about your "-name *.sh" clauses; what is going to process those * ? It'll be the shell won't it? [01:55] TJ- reading the man page it seems like that shouldn't be an issue with the -exec \; version as it serially sends it to sed. [01:55] weaksauce: you need, I think, "-name '*.sh' " - single quotes around them [01:55] weaksauce: you want find to handle the * not the shell [01:55] TJ- ah. i will try that [01:58] TJ- no dice. no error just no editing of the file [01:58] TJ- https://gist.github.com/anonymous/ca2bd1bc4a30e9b351d8e7334e8f74ab [01:58] that is a more complete picture as the other one was edited a bit [01:58] weaksauce: does the command return file names for sed to process? [01:59] the first find does in fact print them out yes [01:59] there are two finds with almost identical predicates [02:01] weaksauce: try this, I did something like this earlier for someone else: "... -exec sh -c "sed -i -e '$SUB' {}" \; " [02:07] TJ- tried a few variants of that and nothing is giving an error but it's not doing anything [02:07] ne1 have any really good fonts for coding [02:09] weaksauce: hmmm, if you remove the -exec it does print out the file names that matched? [02:10] weaksauce: I'm wondering if this is due to running under zsh. Have you tested it with other shells? [02:10] i haven't no === gms is now known as Guest65887 [02:12] TJ- changed the script to #! /usr/bin/env sh and it's still the same. ran it under sh in my terminal too [02:13] every time i want to like find I find it fails me hard [02:13] maybe i can use xargs and pipe it [02:20] weaksauce: OK, I see your problem. You need to surround your logical or's with $ .... $ [02:20] weaksauce: this works for me (to echo the command) find ./$WEBEXT_NAME $ -name '*.json' -or -iname '*.js' -or -iname '*.sh' -or -iname 'license' -or -name '*.sh' $ -exec echo sed -i -e $SUB {} \; [02:20] that works inside a script? [02:21] weaksauce: the ORs need combining to all bind to the -exec [02:21] ah! [02:21] what a powerful but fickle tool [02:22] that worked! thanks TJ- [02:22] yes, it is, it's great for catching you out === leion1 is now known as leion [02:22] it feels like it should be a little easier to do find and replace in a bunch of files [02:24] Unix philosophy; one tool for each task and pipeline their stdout/stdin [02:25] yeah. i didn't mean by find or sed but more from a third party. [02:26] It'd be so specialised then it probably wouldn't get used, whereas shell + find + sed lets you do anything you want - when you figure out how to use them :D [02:27] :D === leion1 is now known as leion [02:34] I've got a bunch of files that didn't come with extensions. I can use my browser's content-sniffing on some of them, but I'm wondering if there's a more general-purpose command-line tool I can use. [02:35] Hello I need help, I want to create a user+pass but on a specific folder. Then use an ftp client... [02:37] Simplest way: Create new user. ln -s whatever folder you want to let them at in their home folder. [02:38] (You'll need to give the new user read/write permissions to that folder so they can access it.) [02:39] Then assuming you've got ftp running, they can access it via their ftp. [02:39] * you've got your ftp daemon running [02:39] I do not have ftp install but I'm able to log in the regular home folder by ftp... [02:39] guys [02:40] whois [02:40] I did a choen -R myuser:www-data /var/www/myfolder [02:40] *chown [02:42] picarda: That doesn't actually make too much sense to me. There's not really the concept of "log into a folder" here, just accounts and such afaik. Perhaps someone else will be able to help, here? [02:44] DDR: I understand your point...I just did it like this because I'm not a pro... [02:45] It will be better to install an ftp server then create account... [02:48] TJ- Great! I'll look at the your blog. Looks like you have a lot of deatils info on there. Will be a good read :) === cthulhu is now known as Guest15369 [02:49] lol === BrAsS_mOnKeY is now known as william [03:05] Alright, I'm having issues with firefox [03:06] First, it starts not responding to some queries, but UI elements act fine individually (IE the url bar can be typed into, but enter doesn't do anything) [03:06] Then the program locks up a bit more, I can use the WM to do stuff, but the program softlocks [03:07] Then gnome, my current desktop environment, locks up badly enough that ctrl+alt+f? doesn't do anything [03:07] Thankfully the kernel responds to magic sysrq keycombinations, so I can do a clean reboot, but this leaves me without logs to look through [03:08] Anyone seen this sort of pattern and know where to look?

I just deleted about 10 of them using synaptic. The machine boots fine to my laptop, but will no longer boot to the desktop. [05:08] When I've had this issue, it was caused by an overloaded /boot partition which scrambled the /kernel set up. I suggest you boot from USB, chroot your system and run sudo apt update && sudo apt dist-upgrade [05:09] then reboot without the USB [05:09] hey, i have a small ssd as my storage for my ubuntu os.

Can i safely resize the current partition that includes boot, then make a seperate /boot partition about a 1gb size without losing my data? [05:12] Alobar500, good but by default, the boot partition on 16.04 is only about 250 mb. 8 - 9 kernels would go through that quickly [05:12] Alobar500, prob but backup /data first [05:14] ok.

I'm booted into a live usb into the desktop. But earlier I booted the 2TB drive to the laptop and removed old kernels with SYnaptic [05:20] Alobar500, very good. I have not worked with supersized storage like yours, so my solution may not be effective. ask again in this channel [05:25] hi all. i have a dual boot machine and need to give more space to my ubuntu parition. is it relatively safe to use gparted to shrink the windows partition and move it to the right? [05:26] "relatively" sure. after you backup everything important. note: when I have done this, it broke the win7 bootloader. easily repaired with windows tools, but still [05:26] yeah. that's the thing. i have had to fight windows 10 a few times already [05:27] I've no experience with win10 so can't advise [05:27] ok.

Is it okay to store dev files and even my own code on the windows partition and work on it in my ubuntu parititon? [05:31] bad idea as windows still uses ntfs and your ubutnu storage = ext4. perhaps a shared cloud storage solution? virtualbox / gDrive [05:32] ok. [05:32] then maybe i can just chop off the end of the windows partition and format it as ext4 [05:32] and store everything there [05:32] roadrunneratwast: also alot of dev tools are available on ubuntu, think of single install ubuntu?

I have windows in a virtualbox which I boot 1-2 yearly [05:34] hm. i don't know yet. i have no lurve for the windows [05:34] roadrunneratwast: alot of things can we launched from wine/playonlinux aswell or as cfhowlett suggests vbox [05:35] but a lot of things can not [05:35] roadrunneratwast: like? [05:35] just hardware compatibility stuff [05:35] top [05:35] not everything has linux support [05:35] true [05:35] everythng is supported in windows [05:35] ok. [05:36] hi there, I just run `systemctl restart gdm` in gnome, and now I'm stuck in login page again, input user and password then pop up login page again, I wonder this is a feature or bug? [05:36] jusss: ubuntu version? graphics card chipset? [05:36] lotuspsychje: 17.10 gnome [05:36] lotuspsychje: intel video card [05:37] lotuspsychje: ubuntu on Xorg [05:37] jusss: hmm thats weird indeed, should work wich kernel are you on? [05:38] lotuspsychje: the latest 4.15 from official ubuntu kernel [05:38] !info linux-image-genercic artful | jusss tested booting this? [05:38] jusss tested booting this?: Package linux-image-genercic does not exist in artful [05:38] !info linux-image-generic artful [05:38] linux-image-generic (source: linux-meta): Generic Linux kernel image. In component main, is optional. Version 4.13.0.32.34 (artful), package size 2 kB, installed size 14 kB [05:39] I don't think this is related with kernel [05:39] jusss: try a few tests, like nomodeset or other kernel boot [05:40] jusss: you dont have hybrid graphics with intel right? [05:40] lotuspsychje: like I said, the graphic is normal, I'm stuck in the graphical login page, not tty [05:41] the login page belong to gdm I think [05:41] jusss: im asking because nvidia is a no-go with wayland and can result in a login loop like you experience [05:41] lotuspsychje: I don't have one nvidia card, only intel video card [05:41] ok [05:42] jusss: wayland also result in the login loop? [05:42] lotuspsychje: maybe you can try it on your local machine, see what happens [05:42] lotuspsychje: wayland and xorg both [05:42] jusss: im testing 18.04 both sessions work here, but wayland more laggy [05:43] I meet this case last night, and I delete .ICEauthority and .Xauthorty, I can ge into the system [05:43] I just wonder why this happens [05:44] jusss: alot of bugs on that login loop mate [05:44] jusss: perhaps syslog/dmesg could help us? [05:44] lotuspsychje: aha === leion1 is now known as leion [05:44] lotuspsychje: yeah, you are right, maybe journalctl can log something [05:45] jusss: i would suggest the artful kernel test also [05:45] jusss: system also up to date? [05:45] lotuspsychje: yeah, up to date last night [05:45] jusss: loginloop after an update? [05:46] morning ericus [05:46] lotuspsychje: no, login loop after I run `systemctl restart gdm` [05:46] right [05:46] I just wonder why it cause this case, [05:46] wats up [05:47] jusss: a thread about it here: https://ubuntuforums.org/showthread.php?t=2374885 [05:48] jusss: did you play with gnome extensions? [05:49] lotuspsychje: yeah, I did, but I delete them now [05:51] jusss: just to make sure, your on 17.10.1?µ [05:52] lotuspsychje: 17.10, I just download the iso from ubuntu official website, I'm not sure what it is [05:52] not sure about the number after 17.10. [05:52] jusss: recall when you downloaded the iso? [05:53] lotuspsychje: 1:00 PM, yesterday [05:53] jusss: there are important updates on the .1 [05:54] jusss: but if you say your up to date === leion1 is now known as leion [05:55] jusss: related bug: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1715811 [05:55] Launchpad bug 1715811 in gdm3 (Ubuntu) "GDM crash loop Ubuntu 17.10 (Intel)" [Undecided,Confirmed] [05:57] lotuspsychje: maybe I should re-install gdm [05:57] lotuspsychje: what packages is I need to purge? [05:58] jusss: that could do the trick yeah, look at the bug its mentioned [05:59] ok, the last comment metion 'apt install gdm3 ubuntu-desktop " === Jochen_wvdT is now known as Schlawiner === leion1 is now known as leion [06:16] hi [06:17] EriC^^: Hello Eric [06:17] quit [06:19] aha, if I remove caribou, that I have to remove gdm3 ubuntu-desktop [06:19] WTH? I just want to remove a on-screen keyboard, I have to remove all entire environment? [06:24] jusss: caribou is part of the ubuntu system,hence why it wants to remove desktop [06:24] jusss: just disable the service? [06:24] jusss, it's a small package. why delete [06:24] lotuspsychje: it can not be disable in the 'settings-universal-access' [06:25] cfhowlett: because it sucks! no ctrl no esc no tab, do you call that is a keyboard??? [06:25] jusss: think you need to disable it in systemd services [06:25] this ^^^^ [06:25] lotuspsychje: you even write a systemd service for that keyboard? [06:26] jusss: ubuntu doesnt chooses with services are important for the user= the users choice [06:26] wich [06:26] jusss: like= enable dislike= disable [06:27] anyone know of an online virus scanner for ubuntu? [06:27] !virus | ehO_k [06:27] ehO_k: Antivirus is something you don't need on !Linux, except where files are then passed to Windows computers (perhaps using Samba). See https://help.ubuntu.com/community/Antivirus [06:28] ah ... ONLINE virus checker. no way in 7 hells I would trust that but you do you ... [06:29] https://metadefender.opswat.com/ is good if you want to scan a particular file [06:30] maybe not the most useful for Linux, but good to have on hand === leion1 is now known as leion [06:35] what are policykit-gnome and ubuntu-desktop? they're all gnome? === harindu_ is now known as harindu23 === harindu23 is now known as harindu_ === harindu_ is now known as zuko951 [06:44] nick harindu === zuko951 is now known as harindu_ [06:50] hi [06:51] is using encrypted filesystem more likely to encounter failures === leion1 is now known as leion [07:16] hi [07:17] something ive noticed it upgrades generally fail now, say from 17.04 to 17.10, or 17.10 to 18.04 etc [07:18] it always errors out because it cant stop systemd to upgrade systemd [07:18] is there away around this? === leion1 is now known as leion [07:19] I prefer a fresh install as much as the next person, but sometimes were lazy [07:19] so even update-manager -d errors on the systemd part so everything rolls back [07:24] hi... using ubuntu, there is a handy command line program for removing leading whitespace from a string. i forget the name of that program, what was it, please? [07:25] sed? [07:26] no [07:26] it's a program made for just this specific job [07:27] similar to 'cut', 'tr', 'head' etc.... [07:31] sed "s/^[ \t]*//" [07:33] what is whitespace [07:33] spacebar caracter? [07:33] yes, or tabs [07:33] awk '{$1=$1};1' [07:34] i asked for the name of that program, not how to remove whitespace ... ;-) [07:35] why does it matter, it works === leion1 is now known as leion [07:37] Ben64, because it matters, simple as that ;-) [07:37] ok, forget it, thanks for your help, anyway ... bye [07:38] cool [07:40] hello [07:44] I have been having a problem since updating from 17.04 to 17.10: first of all, it's using more memory than it used to and not using any swap, and second of all, as soon as it runs out of application memory the system hangs for ~15 minutes and when it recovers dmesg is full of page allocation faults [07:45] I have 4 gigs of memory and the last hang occurred when i just was playing 2 videos in firefox and almost nothing else [07:45] causative: pastebin the output of 'free -m' [07:46] right now it's ok, when it comes out of the hang it has used some swap, but it does not use swap during normal operation [07:46] https://pastebin.com/0qR0djdt [07:47] I know it occurs when the available memory runs out because I have a status bar widget showing the amount of application memory [07:47] and every time it hangs, the widget shows all memory used [07:47] and during normal operation it does not show all memory used [07:49] sounds kind of normal [07:49] normal?? [07:49] if you run out of memory, you'll experience bad things [07:49] it should be using swap instead of hanging for 15 minutes [07:49] it is using swap [07:49] and it is using too much memory as well for what it's doing, compared to 17.04 [07:49] I just said it's not using swap during normal operation [07:49] this is after the hang [07:50] if I booted it up clean, it would use all 4 gigs of memory and 0 swap, then hang [07:50] from just browsing the web [07:50] browsers take lots of memory [07:50] it's obviously not normal === bat is now known as Guest28637 [07:51] what's the output of 'cat /proc/sys/vm/swappiness' [07:51] hi i have a question [07:51] 60 [07:52] then it's set up normally. don't run out of memory : / [07:52] use something like htop to see what's eating it all, and take care of it [07:52] it's obviously not set up normally since it was not happening before and it's not using swap! [07:52] but it is using swap... [07:52] I already explained that to you [07:52] it's using swap because it ran out of memory, that's literally what swap is for [07:52] my widget shows swap as well as memory and at the time of first hang since boot it will always show 0 swap used [07:53] it should not hang for 15 minutes or come back with 4000 lines of page allocation faults in dmesg, it should just transfer some things to swap [07:53] it can't always do that [07:53] why not? [07:53] I have an SSD, swap should be fast [07:53] because things need to be in memory to be used [07:53] there is a variable ( i don't remember which one) which determines the swappiness [07:54] if i encrypt my home folder, am i more subject to increase failure of filesystem or having it not fixable after power outtage and stuff like that?.. is it more likely for an encrypted partition to give problems when checking filesystem after unexpected shutdown.. is it harder to fix than non encrypted? [07:54] if it's zero it doesn't swap even it's out of memory [07:54] there's no reason for it to need 4 gigs of memory to play 2 videos in firefox [07:54] it did not used to need that [07:54] harindu_: yep checked that, it's at the default value of 60 [07:54] causative: you should check htop [07:55] it tells me firefox is using the memory [07:55] gnome-shell at second place with 243 MiB [07:56]
