bug#55488: GDM, GNOME: Can't start desktop session after upgrade

[Luis Felipe]

Hi Ludo,

Since its been a while, lots of commits have gone into master and 
https://issues.guix.gnu.org/55444 is solved, I decided to reconfigure the 
system, and try again. Unfortunately, I still can't start a GNOME session. I 
update the system information below and provide the data you asked for in the 
last message.

My current system generation that presents the same issue is this one:

Checking /var/log/messages for the restart after system reconfigure, I see 
several lines that have errors, one of which is CRITICAL:

But I sent the whole log to you privately just in case.

After trying to log in to GNOME, running "sudo herd status" displays pretty 
much the same as before:

Running "guix system vm config.scm", where config.scm is the same minimal 
config in comment 2 (https://issues.guix.gnu.org/55488#2), the problem is still 
there and it is pretty much the same as in the original's report VM session: I 
log in, but the desktop session never starts; I'm taken back to log in screen. 
The only difference is that this time the log in form does not present problems 
on subsequent tries.

Finally, moving files from /var/lib/gdm out of the way does not help. The 
problem persists.

For what it's worth, this is my machine information:
