i am running ubuntu 12.04 64-bit and i have a nvidia Geforce GT 650m, it was running fine with 1920 x 1024, except a lot of tearing everytime i ran videos. I thought activating the nvidia driver maybe would fix this. When entering "nvidia X server setting" it says " you do not appear to be using nvidia X driver. Please edit your X configuration file ( just run "nvidia-xconfig" as root), and restart the X server. I did and then the computer reboots with a resolutioin of 640 x 480. How can i restore the previous settings, or preferably get it to show full resolution without tearing ? When i enter "nvidia X Server Settings" now it still says the same as above, " do not appear to be using nvidia X driver" when i go to "system settings, additional drivers" it says nvidia_current --> "This driver is activated but not currently in use"
