nvidia driver problems


I just installed Dapper yesterday. I followed the instructions at http://ubuntuguide.org/wiki/Dapper#H...r_.28NVIDIA.29 and edited my xorg.conf file so Driver "nv" is Driver "nvidia". When I restart X with this one change I hear the Gnome startup sound and the screen goes black. I am guessing this means my monitor doesn't support a resolution or refresh rate that X is trying to use.

When I change the driver back to "nv" X starts up normally. Why can't I load X with the nvidia driver and how can I fix this?

Thanks in advance.

What happens when you;
sudo modprobe nvidia
Also check the log (I don't use Ubuntu but should be)
/var/log/Xorg.0.log
or
/var/log/Xorg.o.log.old (You want the one when it didn't work)

running sudo modprobe nvidia rendered no output.

I checked /var/log/Xorg.0.log.old and the only section that had warnings or errors was this one:
Quote:

can you quote the section of xorg.conf that says device "screen" as well? Does it run your monitor at the right resolution/refresh rate before you change the driver from nv to nvidia? You can and should be able to get the resolution stuff sorted out before you switch drivers, so you can isolate if its a driver problem or a screen size problem.

I have two monitors so I will eventually have two screen sections but right now this is my only screen section in xorg.conf:

Quote:
Section "Screen"
Identifier "Screen1"
Device "nvidia1"
Monitor "SyncMaster"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
EndSubSection
EndSection
Here is the ServerLayout and commented out DRI section also:
Quote:
Section "ServerLayout"
Identifier "Default Layout"
# Screen 0 "Screen1" 0 0
# Screen 1 "Screen2" LeftOf "Screen1"
# Option "Xinerama" "On"
Screen "Screen1"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
# InputDevice "stylus" "SendCoreEvents"
# InputDevice "cursor" "SendCoreEvents"
# InputDevice "eraser" "SendCoreEvents"
EndSection

#Section "DRI"
# Mode 0666
#EndSection
