Description customercare 2026-05-27 10:26:45 UTC
System got upgraded from F42 to F43 and gmd failed starting the gnome-session.

I guess, because of the switch to wayland.

Versions:

gdm-49.2-2.fc43.x86_64
gnome-session-49.2-2.fc43.x86_64
gnome-session-wayland-session-49.2-2.fc43.x86_64
glib2-2.86.5-1.fc43.i686
