[arch-general] Set ip lan address /etc/environment
by Maykel Franco 05 Jun '18

05 Jun '18

Hi, I put this text in /etc/environment: $ source /etc/environment ip="$(ifconfig | grep -A 1 'eth0' | tail -1 | cut -d ':' -f 2 | cut -d ' ' -f 1)" $ echo $ip 192.168.0.33 Works fine, but when I reboot my archlinux: $ echo $ip $(ifconfig | grep -A 1 'eth0' | tail -1 | cut -d ':' -f 2 | cut -d ' ' -f 1) What's happened?? Is necessary exec source /etc/environment after every reboot? Thanks in advanced.

[arch-general] KDE plasma, baloo and UI/video playback freezes
by Francesco Porro 02 Jun '18

02 Jun '18

Hi, My problem is: when I'm watching a video, running Konversation in the background with logging on disk enabled, the playback of video slows down, freezes for a while. Running iotop and ksysguard I found that baloo_file_extractor is writing on disk a big amount of data, filling the write queue; balooct monitor shows baloo is indexing Konversation's logs file changes. Peaks of 60-90 MB/s of data on mechanical hdd are generated and the playback of videos (or audio, or other GUI-related tasks) slow down or freeze. Very very annoying. I'm running updated versions of: KDE plasma (5.12.5), kernel (4.16.7), baloo (5.45); CFQ I/O scheduler on sda. On the same machine, the same version of softwares, the same configurations (of programs, mounts, IO scheduler) BUT on a Debian sid install (home is shared between installs) is NOT showing the same issue. On Debian, playback is running smootly even if baloo_file_extractor is heavly loading IO writes queue. On each installation I added this tweaks, to improve Vm management by the kernel: [frapox@tungsteno ~]$ cat /etc/sysctl.d/local.conf vm.dirty_background_ratio = 2 vm.dirty_ratio = 5 vm.vfs_cache_pressure = 60 I also tried to recompile the Arch kernel with CONFIG_PREEMPT_VOLUNTARY=y, to reflect the same default compile setting of Debian, but the issue wasn't solved. So i'm wondering which other config files or settings/tweaks I can look into to overcome this issue on Arch linux (I'd really love to keep on use Arch as my main OS). Thanks in advance. -- fp

[arch-general] Why on 1st run does pacman -Qi take so long? (15 seconds waiting for Qi?)
by David C. Rankin 02 Jun '18

02 Jun '18

This is new, after the latest pacman update along with 4.6.13, when running $ pacman -Qi somepackage for the first time it takes 15 seconds for any response. E.g., $ time pmqi colord Name : colord Version : 1.4.3-1 Description : System daemon for managing color devices Architecture : x86_64 URL : https://www.freedesktop.org/software/colord Licenses : GPL2 Groups : None Provides : None Depends On : lcms2 libgusb polkit sqlite systemd dconf dbus libgudev shared-mime-info Optional Deps : argyllcms: color profiling colord-sane: SANE support Required By : gtk3 Optional For : cups Conflicts With : None Replaces : shared-color-profiles Installed Size : 6.60 MiB Packager : Jan Alexander Steffens (heftig) <jan.steffens(a)gmail.com> Build Date : Sat 21 Apr 2018 02:58:03 PM CDT Install Date : Sun 22 Apr 2018 09:59:37 PM CDT Install Reason : Installed as a dependency for another package Install Script : No Validated By : Signature real 0m15.083s user 0m0.011s sys 0m0.194s That's 15 seconds waiting for something that wasn't there before? Subsequent -Qi queries are against near instantaneous as they have always been. Is there something new that causes some type of handshake or authentication that takes time to establish on 1st call. -- David C. Rankin, J.D.,P.E.

[arch-general] Archlinux ISO 2018.06.01 lost rankmirrors
by Óscar García Amor 02 Jun '18

02 Jun '18

Hi! With the split of pacman packagein pacman and pacman-contrib, the Archlinux ISO of current month (2018.06.01) lost the rankmirrors. I think that the ISO should include the pacman-contrib package because the use of rankmirrors is a recommended task in Arch installation. Greetings. -- Óscar García Amor | ogarcia at moire.org | http://ogarcia.me

Indeed. Is it for consumption of users whose shell you don't know? Is it for scripts, like cron jobs? In the former case, see what is in /etc/shells, and drop a script to /etc/profile.d, one for each shell. But that will be for login shells. In the latter case, I am afraid you need to define it each time... Finally, a bit of a puzzle, what are you going to do when the network goes down, i.e. should the variable be unset or updated?

I have docker services in which I use variables and I want to pass the always updated ip variable. If the network goes, it is not a problem, it will always have the same fixed static ip.

[arch-general] Where can I 'setterm -blank 5 -powerdown 6' as part of the boot process/systemd startup?
by David C. Rankin 01 Jun '18

01 Jun '18

All, /sys/module/kernel/parameters/consoleblank is set to 0 by default in a change that occurred a while back. Since then, the normal text console will no longer blank or powerdown leaving your monitor on 24/7. This affects a couple of Arch servers I have. Since then I have just been turning the monitors off. Where in the boot/systemd startup can I call setterm to re-enable to normal console blank and powerdown? Remotely I can call: # TERM=linux setterm -blank 5 -powerdown 6 >/dev/tty0 </dev/tty0 to enable blank and powerdown post-boot, but I simply want to set this to be the default. Where best to set this? (passing the kernel parameter 'consoleblank=300' does not enable powerdown, so both must be set) -- David C. Rankin, J.D.,P.E.
