problems with gdm, can't go to any desktop

[Antonio Olivares <olivares14031 yahoo com>]

Dear fellow testers,

I have a little problem, I think the culprit is gdm.  I start my computer and I try to login to a user and it gives me the login screen again.  I do it again and the same thing happens.  I then restart my machine in level 3 and login as myself and type startx and my X session begins.  

Video Card is an ATI radeon, hopefully will be ready for that TEST DAY?

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]

[root riohigh ~]# rpm -qa gdm*
gdm-2.26.0-7.fc11.i586

This happens on only one machine, the other one logins fine automagically :), and it has INTEL chipset(Toshiba Laptop)  

Regards,

Antonio
