Since my last update with Fedora 39, I can no longer access the wayland session from gdm (I’m using sway). Only X11 sessions are shown, and gdm starts in X11 mode (I can see the X mouse cursor briefly).
There is no particular error in the gdm logs and I specifically set in /etc/gdm/custom.conf:
WaylandEnable=true
(just to be sure, the setting was commented out before)
Still gdm fails to start with wayland. However sddm is correctly showing all wayland sessions.
The gdm logs since boot:
