I got a problem with my laptop with Ubuntu 12.04. It has an nVidia GT540M video card which uses Optimus, which I want to use under Ubuntu. So far I tried:
- Installing the official nVidia drivers.
- Added the x-swat and Bumblebee repositories (as described here in the Ubuntu wiki)
- Tried to change xorg.conf manually.
Nothing has worked. Any clues?
