Re: gdm3 stalled

[Ralf Mardorf]

"If GDM is failing to work properly, it is always a good idea to include
debug information. To enable debugging, set the debug/Enable key to
"true" in the <etc>/gdm/custom.conf file and restart GDM. Then use GDM
to the point where it fails, and debug output will be sent to the system
log file (<var>/log/messages or <var>/adm/messages depending on your
Operating System)." -
