gdm restart infinitely

Salamo Alikom
when i start gdm to log in ,i found it restart infinitely .
my log files :

So are you saying that you don't get a login prompt? Or is this happening when you logout of your X session. When you start gdm from bootup gdm is set to respawn. Assuming this is in regards to booting up to gdm then logging out I believe you can tell it not to respawn in the /etc/inittab file. or /usr/local/etc/inittab can't remember off the top of my head.

ok so I just got it installed and actually I was wrong you can modify the ttys by editing /etc/ttys
