Hi,

Xorg crashes when I disconnect the external monitor. This happens both on i3 and xfce4, but not on sway --unsupported-gpu. It happens whether gdm is active or not.

System: Asus TUF Gaming F15, Fedora 43

Journalctl output from around the time it happens: Feb 12 08:51:06 f15 /usr/libexec/gdm-x-session[10256]: (II) modeset(0): EDID ven - Pastebin.com

Very grateful for any pointers on how to solve this!

The same issue happens for me for several weeks. Everytime I change the monitor order, or if I attach my TV as external monitor, the xserver session crashes and I have to login again.

core dump looks almost the same as for Kenneth.

❯ cat /etc/fedora-release 
Fedora release 42 (Adams)

Are there specific log files I could contribute for debugging purpose that would help?
