[arch-general] Possibility of including xorg input patch
by Kirill Churin 25 Jul '15

25 Jul '15

Can this patch https://bugs.freedesktop.org/attachment.cgi?id=33142 be applied to Arch's xorg? It solves famous problem https://bugs.freedesktop.org/show_bug.cgi?id=865 with broken keyboard input for users who use multiple keyboard layouts without any noticeable side-effects. It's known this patch has been applied in Ubuntu. -- Kirill Churin Jabber: reflexing(a)reflexing.ru, ICQ: 8163230, Skype on demand.

[arch-general] Systemd screen brightness
by Michael Nawrocki 03 Jun '13

03 Jun '13

Hey everyone, I'm trying to get my laptop backlight keys (fn+f6/f7) to adjust the brightness of my toshiba laptop backlight. Previously, I had entered the following in my /etc/acpi/handler.sh to handle the acpi events generated when those keys were pressed: video/brightnessdown) echo $(($(cat /sys/class/backlight/acpi_video0/brightness) -1)) > /sys/class/backlight/acpi_video0/brightness ;; video/brightnessup) echo $(($(cat /sys/class/backlight/acpi_video0/brightness) +1)) > /sys/class/backlight/acpi_video0/brightness ;; However, as I am working on migrating to systemd, acpid no longer runs and hence does not handle these events. How can I write a similar handler into systemd? Thanks, Mike

[arch-general] System doesn't load LVM volumes when booting in single user mode
by David Rosenstrauch 13 Feb '13

13 Feb '13

Like the subject says, when I boot directly into single user mode, system doesn't load my LVM volumes. So the only way I can realistically use single user mode (since many of my key files are on LVM volumes) is to boot the system to multi-user mode, and the "telinit s" to drop back down to single user. This seems like an error, and that systemd should be starting LVM volumes even in single user mode. Anyone have any idea what the problem might be and/or a workaround? Thanks, DR

[arch-general] Fail to run startx
by Lu, Boying 03 Dec '12

03 Dec '12

Hi, All, I followed the instructions at https://wiki.archlinux.org/index.php/Beginners%27_Guide#Configure_pacman and https://wiki.archlinux.org/index.php/VirtualBox#Arch_Linux_guests to install the ArchLinux 2012.11.01 in VirtualBox (v4.2.4). My host OS is Windows XP. After installing the base system, I tried to configure X. But 'startx' failed and I found following error messages in the /var/log/Xorg.0.log: AIGLX error: vboxvideo does not export required DRI extension AIGIX: reverting to software rendering Can anyone tell me how to fix this? Thanks in advance. Boying

[arch-general] Boot loaders for Linux that can also boot FreeBSD
by Ralf Mardorf 29 Nov '12

29 Nov '12

Hi :) my apologies for cross-posting this to several Linux mailing lists. I need a boot loader for Linux, that is comfortable to use for my needs, a Linux multi-boot with trillions of Linux installs, trillions ^ 2 kernels and (trillions ^ 2) * 1024 entries with different boot options, so something as GRUB 2 is unusable for my needs. Until now I was comfortable with GRUB legacy, but now I add a FreeBSD install to my machine and against the claims at http://en.wikipedia.org/wiki/Comparison_of_boot_loaders GRUB legacy does not boot FreeBSD (until now). I was thinking of SYSLINUX, perhaps the most popular bootloader by Linux experts, but the Wiki says it doesn't support booting BSD. Since access to the freebsd-ufs partition by Linux is a PITA and Linux is most important for me, I wont use a FreeBSD bootloader. I need easy access to the bootloader's configuration file. I still continue searching with Google. Any hints are welcome! On a FreeBSD mailing list somebody wrote: > You might want to try a chainloader boot from grub. The following is a > chainloader rule that I have used, as well as a normal loader boot. I > use the loader boot, but I also tested the chainloader boot. You will > need a ufs2_stage1_5 file in your grub directory for a loader boot, and > linux grub might not have it available. > > title FreeBSD, sda3 (oak) chainloader > root (hd1,2) > chainloader +1 > boot > > title FreeBSD, sda3 (oak) /boot/loader > root (hd1,2,a) > kernel /boot/loader > boot Yes, ufs2_stage1_5 is missing, so when I tested #title FreeBSD #root (hd0,a) #kernel /boot/loader title FreeBSD rootnoverify (hd0,1) chainloader +1 boot there was no error, but nothing happened, without the chainloader an error 17, cannot mount selected partition appeared. I wonder that so many *NIX users nag about Windows, but support to access Windows files and to multi-boot with Windows is that easy. I don't have Windows on my machine. I hope somebody is experienced with multi-boot machines using different *NIX operating systems and will help me. Regards, Ralf

[arch-general] Deleting fontconfig symlinks
by Lewis Pike 29 Nov '12

29 Nov '12

Previously, my way of disabling parts of the default fontconfig configuration was to delete the related symlinks in /etc/fonts/conf.d. Now that these symlinks are owned by the fontconfig package rather than created during the post-install script [1], I'm finding that these deleted symlinks are restored whenever fontconfig is upgraded. This has the effect of silently modifying my font configuration. 1. What is the recommended way of disabling parts of the default font configuration such that it survives an upgrade of fontconfig? 2. Is simply changing any unwanted symlinks owned by fontconfig to point to /dev/null an advisable solution? 3. If /dev/null is used as a target what will pacman do when fontconfig is upgraded? --Lewis [1] https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=package…

I spoke too soon. This doesn't work within X or tmux. su fails with a PAM_SESSION_ERR message: su: cannot not open session: Cannot make/remove an entry for the specified session I think pts/<int> is for some reason considered an invalid argument for tty. See logging output below. I first enabled debugging: -session required pam_systemd.so kill-session-processes=1 +session required pam_systemd.so kill-session-processes=1 debug=1 Then tried both cases: 1) logs from the tty case which works: Nov 27 13:28:21 arch64 su[31178]: pam_systemd(su:session): Asking logind to create session: uid=0 pid=31178 service=su type=tty class=user seat=seat0 vtnr=2 tty=tty2 display= remote=no remote_user=user remote_host= Nov 27 13:28:21 arch64 systemd-logind[955]: New session 47 of user root.

[arch-general] Gentoo udev fork w/o systemd
by Jérôme Bartand 27 Nov '12

27 Nov '12

I want to bring to your attention that Gentoo is working on a udev fork called eudev that will - respect the Unix philosophy - be POSIX-compliant and get rid of glibcisms - have no unnecessary dependencies (systemd, kmod) - support separate /usr http://thread.gmane.org/gmane.linux.gentoo.project/2262 with the goal to make it default for Gentoo in the future, along with OpenRC. I know from past discussions on this mailing list that not everybody in the Arch community is happy with systemd. They are looking for contributors and this is an opportunity for cross-community collaboration. Regards, -J
