Hi everyone,

since I have upgraded xorg a few days ago on my arch linux system the
xorg server crashes approximately twice a day. I have attached my
Xorg.0.log.

My system logs tell me:

Can I provide more information in order to track down the problem? Any
help is appreciated!

this indicates an assert in libinput, which indicates that there's a bug in
libinput. Please file a bug here:
https://gitlab.freedesktop.org/libinput/libinput/issues, following the
steps here:
https://wayland.freedesktop.org/libinput/doc/latest/reporting-bugs.html

ideally you could try to figure out what input sequence triggers the bug and
record it, should be easy to fix if reproducible.

Cheers,
Peter

Hi Peter,

thanks a lot for your reply! I will file the bug as soon as I am able to
reproduce it. I have the feeling that it has something to do with
scrolling when I am using my touchpad for it.

Cheers,
Philipp
