Since you say the problem only happens with X11 and not Wayland, I
assume that refers to the choice of login session. Worth noting that the
login screen itself uses Wayland and not X11 :)
So if the only problem here is starting X sessions, please:
1. Reboot to clear the system log.
2. Try to log in with X11 once, it should fail.
3. Reboot the system again, immediately.
4. Try to log in with Wayland, it should succeed.
5. Run this command to gather the log of the failed attempt:
journalctl -b-1 > prevboot.txt
6. Run these commands to give us extra information about the system:
dmesg > dmesg.txt
lspci -k > lspcik.txt
7. Attach all three text files here.

Title:
Gnome Xorg sessions fail to start with LDAP users (but Wayland or
local users work)
Status in gdm3 package in Ubuntu:
Incomplete
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
When trying to login to Gnome with an remote user from an LDAP (LDAP
is available and connectable when in GDM) using X11, GDM loops around
three to five times before actually granting access to the desktop.
This does not happen when
a) Wayland is used instead of X11 or,
b) the LDAP server is not reachable during login, using X11, or
c) a local user is logged in instead, using X11
The LDAP connection is established using the Univention Domain Join
