Dual screen disabled after installing recomended video card jsk drivers.

Asked by Mads Fisker on 2012-08-28

I just installed 12.04 lts, and jumped to my settings and enabled both my monitors, no problem in detecting them.
then i installed the "additional drivers" (Nvidia acclerated graphics driver (version 173)). rebooted and bam, now only one monitor is detectede in the display options. and it says is a laptop monitor.

i've tryed the 4 different drivers avaliable in the additional drivers option, but to no avail. im still stuck on one monitor.

what do i do?
