My Phoenix installation has been working fine for a few weeks now. Yesterday at some point the system became unresponsive for an unknown reason and I hit Ctrl+Alt+Backspace, being in a hurry. The screen flashed several times trying to start x again but failed, complaining about the server already running.
Now I can only boot into X as root properly. Booting as a user starts x, shows the nvidia logo and then I'm dumped to a black screen with the X cursor on it.
Any configuration files I can check to figure out what the problem is?
