blank screen on /etc/init.d/gdm [re]start

[mutsuura <attila@mutsuura.com>]

Hi All

I have a fresh install on a Gateway E4100. After a net-install and 
standard configuration, I reboot the machine.

I see the standard startup text scroll by on the screen but when it gets 
to the point of starting gdm - I get a blank screen.

ALT-CTL-F1 gets me to the command line gdm login screen. I can log in as 
root or user I created during install.

I tried different monitor - still blank screen.

Tried different monitor settings - still blank screen.

Rebooted with UBUNTU LIVE CD - that works properly. I manage to get into 
gnome under ubuntu's monitor detection scheme [ruling out any hardware 
problem].

I used the same net-install disk & procedure as on my home machine. 
Everything works properly at home.

I tried the /etc/X11/XF86Config-4 from home (see attached) - still blank 
screen!

I tried to "find" a 'xorg.conf' file on my system but there doesn't appear 
to be one.

Should I uninstall gdm and reinstall it via dpgk?

~>:-((((

Would appreciate specific suggestions? -references?

Is there a startup log file I can download that would give a clue to the 
problem?

Much thx

Attila
