I'm trying to be able ubuntu graphical effects and unity 3D with the video card in the title on my samsung np300e5a. They seem to run fine with a live cd or usb but they don't on a fresh install.
I initially didn't know that the video card actually was a double one (integrated intel+dedicated nvidia) with OPTIMUS technology, and Bumblebee was the official tool to make it work, so I installed the official sh script downloaded from the nvidia website. It didn't work, so I uninstalled it.
I tried to install bumblebee, but the result was a unbootable system. The only way to start it (without the graphics) is to run recovery mode and resume normal boot. When I try to run startx I get the error "fatal server error: no screens found".
Is there a way to to make my video card work properly on my ubuntu 12.04.2 (with graphical effects and 3D acceleration when needed)? I searched thoroughly the web and seems that other people with my same hardware can make it work, but for some reason, I can't...
if further infos or details about my system configuration or done operations are needed, I'm up to complete the description.
