Hey, I'm having a problem with getting GDM3 to automatically login (I have the drive encrypted, requiring a password at boot; it's a "single user" machine, so I figured that typing two passwords is a little redundant). I edited the configuration file /etc/gdm/custom.com, and it now reads:
# GDM configuration storage
### User Added Settings ###
and then restarted, but no luck. Any pointers?
