I have both an AMD ( HD 7850 ) and an Nvidia ( 8400 GS ) GPU installed on my motherboard.
The Nvidia card is only there because of its S-video port, which I use to output to my old'n'bulky CRT TV. I have no need of it in Ubuntu, and things seem to get fussy at times because of its presence.
I was wondering if there was any way to make Ubuntu ignore its existence. I know that it's possible to disable the Nvidia GPU in Windows via the device manager, but I've so far been unable to find a similar method in Ubuntu. Any ideas?
Please let me know if there is any other information that I should provide :)
