I have a similar problem with my card, a
GF4Ti (4200) , 128 MB .
I installed RPMs for SuSE 8.0 (kernel and glx)
from the command line, X-server not running.
No complaints during installation with "rpm -ivh xxx" (all according to Nvidia's installation instruction).
I used the X-Config program "sax2" to configure the display. I set it to 1024-768, 16,7 million
colors, 85 Hz V-sync. I chose the correct Nvidia
graphic card and activated the glx-option in
the 3D-properties. I did not play with any
expert-options in sax2.
The monitor can handle the resolution and frequencies. I also have Window-XP running on the
same disk and there everything works fine.
When I then try to test the X-server the monitor
becomes black and stays like that.
The system freezes.
The same when I just save the X-configuration
and start the X-server by runlevel 5 i.e.
The only choice I then have is to power off.
When I press CTRL-ALT-BACKSPACE the system
powers off immediately.
When I use the card setting "VESA, 1024x768, 85 Hz" all is OK.
I don't know what is wrong.
I trusted in sax2 and did not try to find an
error in the X-configuration file.
Maybe I should, but what should I search for?
