I use Slackware 10.1 and XFCE.
I want to get graphic login by the "id:4:initdefault". After boot without error, I type the right username/passwd in the graphic login prompt and after 2-3 secs dark screen I get the login screen again. This happens with both common user and root.
But I could do successful text login, then startx normally.
My case is a little similar with this one,
I have tried to remove all the scripts in /etc/profile.d, but no help
