Package: gnome
Version: 1:43+1
Control: affects -1 gdm3/43.0-3

After upgrading from a mixture of Debian 11 and 12 to Debian 12, Gnome started to run Xorg on login instead of Wayland, whereas previously, Wayland had been used. In uxterm, we see

$ echo $XDG_SESSION_TYPE
x11
$ grep -i Wayland /etc/gdm3/daemon.conf
#WaylandEnable=false

In the journal we find, among other stuff, this:

No monitor is connected to the VGA port connected to the ASPEED card, and a single monitor is connected to the DisplayPort port of the GeForce video card.

No proprietary Nvidia drivers are installed:

As the machine was previously able to run Wayland, it's (hopefully, in an error-free way) possible in principle. My wild guess is that the current logic preventing Wayland to run (and generating WaylandEnable=false in /run/gdm3/custom.conf) might be flawed or too strong; cf. https://gitlab.gnome.org/GNOME/gdm/-/merge_requests/171#note_1403697. Still, I might be wrong on this. I kindly ask the maintainers and developers for attention to this bug report.

Off-topic, might be related: now (i.e, using xorg), automatic suspend after a certain timeout doesn't work (the machine remains up and running), but a manual suspend via gnome menu does work. I'm going to post another bug report on this.

Gratefully,
AlMa
