Xorg core dump when upgrading packages

Frequently, when I upgrade packages via pacman -Syu, I'm thrown out to the login screen. When I look at the logs in the journalctl, it says something like this:

This happens only when I upgrade packages. If nessesary, I can provide some other logs or something like that. Please, help me! =-)

Re: Xorg core dump when upgrading packages

See here, https://bbs.archlinux.org/viewtopic.php?id=286408 and https://bugs.archlinux.org/task/77789 I am testing the fix linked there and so far, no dump

Re: Xorg core dump when upgrading packages

I have edited /usr/share/libalpm/hooks/30-systemd-udev-reload.hook

[Trigger]
Type = Path
Operation = Install
Operation = Upgrade
Operation = Remove
Target = usr/lib/udev/rules.d/*

[Action]
Description = Reloading device manager configuration...
When = PostTransaction
Exec =
#/usr/share/libalpm/scripts/systemd-hook udev-reload

comment the exec line

Re: Xorg core dump when upgrading packages

You shouldn't comment the exec line, but adjust /usr/share/libalpm/scripts/systemd-hook and comment the

udevadm trigger
udevadm settle

lines so that the potentially necessary reload of new rules can properly happen, while not triggering a mostly unnecessary reload of everything.

FWIW the Xorg coredump is mostly due to having bogus evdev configuration flying around you probably want to get rid of

grep -R evdev /{etc,usr/share}/X11/xorg.conf.d*

some remnants of that in a /usr/share/X11/xorg.conf.d/10-quirks.conf is normal, any other file likely superfluous and wrong/unnecessary.

Re: Xorg core dump when upgrading packages

Based on the code in /usr/share/libalpm/scripts/systemd-hook

    if [ ! -e /etc/systemd/do-not-udevadm-trigger-on-update ]; then
      /usr/bin/udevadm trigger -c change
      /usr/bin/udevadm settle
    fi

maybe creating a file to skip the triggering of evdev would be a better approach

/etc/systemd/do-not-udevadm-trigger-on-update

Re: Xorg core dump when upgrading packages

That solution was added in the latest new revision of the systemd package and not present when this first appeared. So yes it's a "better" solution now, but it's ultimately doing the same thing.
