I got the same problem with my Nvidia Geforce 4, except that half the
time it was in 1024x768, half the time in 640x480.
It appears that the new system-config-display doesn't enable the hard
coded screen settings in your /etc/X11/xorg.conf. Instead, it relies on
DCC probes. My monitor/card combination has some problem, and the DCC
Probe fails half the time. To work around this, edit /etc/X11/xorg.conf
and look in the Monitor section. Uncomment the HorizSync and the
VertRefresh lines.
Section "Monitor"
### Uncomment if you don't want to default to DDC:
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Lite-On A1770NSL"
DisplaySize 320 240
### Uncomment if you don't want to default to DDC:
HorizSync 30.0 - 69.0
VertRefresh 50.0 - 120.0
Option "dpms"
EndSection
Hope that helps.
