Public bug reported:

A Lenovo P53 is installed with ubuntu 18.04.5 LTS. 
Graphics Intel UHD Graphics 630 (main display), nvidia quadro RTX 5000 also 
installed but not used for main display. 

Laptop is domain joined. When logging to the local ubuntu user, there is
no problem detected. Then, if we log out and try to login with a domain
user, gnome crashes.

>From what I can see in the logs, the user is authenticated correctly,
but then in the instantiation of the session, gnome.shell.desktop faces
an unrecoverable failure.

>From auth.log

```
