Default Re: Ubuntu - Nvidia driver with dvi monitor distorted

That worked! Thanks netllama for all your help. :-)

Although, not on the first try. I had the wrong HorizSync "31.5 - 48.4", just something I chose haphazardly, so the Ubuntu login screen was burned into my pixels for an hour or so.

While the pixels were returning to normal, I booted into windows and checked the settings with my monitor's on screen menu. It was running 63.9 KHz and 60Hz.

2nd try was a success! I tried to use a depth of 32, but the X server didn't start b/c it thought 32 was not supported, resulting in no supported screen modes. Any way to ignore this, too?

My xorg.conf looks like this now:

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 61 - 64
VertRefresh 60
Option "DPMS"

Section "Device"
Identifier "nVidia Corporation NV25 [GeForce4 Ti 4200]"
Driver "nvidia"
Option "UseEDID" "False"
Option "ExactModeTimingsDVI" "true"
Option "ModeValidation" "NoDFPNativeResolutionCheck"

Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation NV25 [GeForce4 Ti 4200]"
Monitor "Generic Monitor"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1280x1024" "1152x864" "1024x768" "800x600"
SubSection "Display"
Depth 32
Modes "1280x1024" "1152x864" "1024x768" "800x600"
