I've edited /etc/gdm/custom.conf to show the following:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=username
Where username is obviously the username I'd like to automatically log into.
I don't know if it matters or not, but I do have multiple users. In mind this should not matter, however, since we're specifying a username here in the settings.
I'm using RHEL6.4. Any ideas?
