Code: Select all
lsmod | grep nvidia
One with nvidia alone and one or two depending on nvidia - nvidia is shown to the right
If you don't fine nvidia here time to check your xorg.conf
Code: Select all
gksu gedit /etc/X11/xorg.conf
With one monitor there should be just one Section Device looking like this
There might be some options - leave them as isSection "Device"
Identifier "Configured Video Device"
Driver "nvidia"
EndSection
The only other options for Driver are "nv" or "vesa" - if so take a note of which it is and change to nvidia
If you did not find nvidia in lsmod but find it here time to call for more help
(lsmod lists all loaded kernel modules - roughly the same as drivers)
