[arch-general] scsi_mod.use_blk_mq (revisited)
by Randy DuCharme 11 May '18

11 May '18

Greetings again, I've been continuing to fool with this. I'm hoping someone smarter than I can shed a little more light on it. Here's what I've discovered since my last post..... It seems that on my system, it takes more than the allowed 10 seconds for the disks to appear. I removed "quiet" from my boot command line and it timed out looking for UUID=xxxx..... . So I looked for it and it definitely was not there. None of the sdXx devices were. I looked again, and yet again (ls /dev/sd*) and after about the 3rd or 4th attempt they showed up. So then, I mounted /dev/sdc3 to /new_root/, typed 'exit' and after a warning about possibly failing to run as a user instance, it booted. Any clues as to why this occurs? I'm trying to find a way to increase the pre-boot disk probe timer if possible. So far, all I've found are tips about speeding up the boot process, not slowing it down. Many thanks in advance. -- Randall DuCharme (Radio AD5GB) Powered entirely by Open Source software.

[arch-general] Less Modified Files from Updates.
by Ralph Corderoy 11 May '18

11 May '18

Hi, After a `pacman -Su', I run this ~/bin/oldpkg script #! /bin/sh sudo lsof -n +c0 | sed -n '1{p;d}; /DEL/{p;d}; / (deleted)$/{p;d}' | g -v ' /(SYSV00000000|dev/shm/org\.chromium\.......|memfd:pulseaudio|tmp/#[0-9]{5,7})\>' | sed '1{h; d}; 2{x; G}' to show open files that are deleted. This helps spot things like Postfix needing a restart, or xfce4-terminal running with old libraries, that kind of thing. A lot of the time I can selectively restart things, log out and back in, etc., to avoid a reboot. Quite often, these three data files appear, /usr/share/icons/gnome/icon-theme.cache /usr/share/icons/hicolor/icon-theme.cache /usr/share/mime/mime.cache triggered by /usr/share/libalpm/hooks. Based on the updated packages, I'm guessing a lot of the time the before and after content is the same, but the file has been re-created and moved in place of the old one anyway. A cmp(1) could avoid the unnecessary churn, though I see it's more complex when an external command is exec'd rather than the re-build done directly. Even so, things like update-mime-database(1) used in update-mime-database.hook has a `-n' option that looks like it might often avoid the new inode. -n Only update if MIME-DIR/packages/ or a file in that directory is newer than MIME-DIR/version. This is useful for package pre- and post-installation scripts. Can churn be reduced? Or am I on the wrong track it detecting what needs to take note of new files? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy

[arch-general] IBus Qt
by Grady Martin 11 May '18

11 May '18

>From <https://wiki.archlinux.org/index.php/IBus>: > Additionally, to enable IBus for Qt applications, install the ibus-qt library. Since 2012, I have used IBus with Qt applications and have yet to encounter a single problem, yet I have never installed ibus-qt. Can anyone clarify this statement from the wiki?

[arch-general] Missing rc-local.service
by Marek Howard 09 May '18

09 May '18

Hello, I'd like to use /etc/rc.local and noticed, that there's something called systemd-rc-local-generator which should somehow pull in rc-local.service on boot, according to its man page. But on my ArchLinux, the service file isn't there, and neither does /etc/rc.local run on boot. Is the systemd in ArchLinux packaged correctly? Thank you. % pacman -Q|grep '^systemd' systemd 238.76-1 systemd-sysvcompat 238.76-1

[arch-general] latest kernel broken?
by Randy DuCharme 08 May '18

08 May '18

Greetings, Just updated my system (pacman -Syu) and was dumped into an emergency shell on reboot. Seems my boot command line option (scsi_mod.use_blk_mq=1) was no longer acceptable. LOL. I haven't seen anything that indicated this was deprecated or obsolete. System is fairly simple. Asus CrosshairV - Formula Z + FX9590. Main disk is a 2T Barracuda and a handfull of WD Raptors on an LSI-9260. System comes up fine removing the boot option. Thanks in advance! -- Randall DuCharme (Radio *AD5GB*) Powered entirely by Open Source software.

[arch-general] Broke Arch trying to change graphics driver
by Junayeed Ahnaf 06 May '18

06 May '18

Hi, So here's what happened, I was facing issue with proprietary nVidia driver (screen tearing) so I thought I want to switch to the free one, so I uninstalled nvidia with "pacman -Rs nvidia" , then I thought might as well try a different kernel and installed zen. Now when I boot into either kernel I am seeing "Starting display manager" then a black screen. I can login to tty2 , but no display comes up. I want to switch back to free driver, with preferably zen kernel. What should I do? Thanks in advance.

[arch-general] kernel config (CONFIG_NO_HZ_FULL)
by Joakim Hernberg 04 May '18

04 May '18

Wondering why the main kernel has been reconfigured from CONFIG_NO_HZ_IDLE to CONFIG_NO_HZ_FULL? The config help has this to say regarding CONFIG_NO_HZ_FULL: "This is implemented at the expense of some overhead in user <-> kernel transitions: syscalls, exceptions and interrupts. Even when it's dynamically off." -- Joakim

[arch-general] Firefox screen tearing
by Junayeed Ahnaf 25 Apr '18

25 Apr '18

Hello, I am using firefox v 60.0b15 installed from AUR. My hardware is: 1. AMD 1600 Processor 2. nVidia 1500Ti GPU running nVidia proprietary driver 3. 16GB 3200MHz RAM There should not be any problem running firefox with this configuration but I am facing weird lag and screen tearing when I turn on smooth scrolling. Things I have tried: 1. Enabled / Disabled hardware acceleration 2. Applied 1.2, 1.3, 1.6, 1.8, 1.10, 1.11 from https://wiki.archlinux.org/index.php/Firefox/Tweaks<https://link.getmailspring.com/link/1524668509.local-c70ad352-4319-v1.2.1-7…> I had scrolling issue before trying anything, still have them. My desktop environment is KDE and Kernel version is 4.16.3-1-ARCH. I have all the updates installed. What can I do to make the tearing go away? Turning off smooth scrolling does solve the issue but I'd like to keep it on. Thanks C
