Gnome problem under squeeze/amd64

[Juan Lavieri <jlavieri@cantv.net>]

Hi all,

I'm having this problem:

I recently installed squeeze amd64 in my laptop and after that I recived 
the gdm login screen.  I tried to login with my normal user account 
(juan) and after I do so,  I receive a blank screen.  I'm able to use 
cntl + alt + f1 - f6 terminals, I can login and execute any console 
command.  But if I back again to the graphical desktop and kill the x 
server with cntl + alt + backspace, I receive the login prompt again but 
if I proceed, now I'm still having the black screen not even the 
graphical desktop but in the character terminals cntl + alt+ f1 -f6 
also.  These consoles are operative because if I execute commands like 
reboot or halt for example, they are executed;  the problem is that I 
can't see anything.

Making some tests I detected that if I discard gnome use and login into 
a twm session everythings works without problem.  The same is true if I 
login into gnome _AS USER ROOT_, I mean I can work without troubles as 
root under gnome (dangerous I know, it's only a test) so I think it's 
not a xorg configuration problem.

Please if anyone has any idea of what's happening.....  help me

Regards


Juan
