Dear Maintainer,

in multiseat setups, GNOME is limited to only support Wayland sessions on seat0.

There are patches for gdm3 and gnome-shell to enable Wayland sessions for all
seats in a multiseat environment. I use these patches on top of the current
Debian sid packages for some months now without any glitches. I also tested
fast user-switching as requested by the author of these patches.

The original source of the patches is here:
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2230/commits

This bug belongs to bug #1031494 which is the gdm part of this issue.
