Is your card dual? If so you have more trouble than you think since ubuntu does not by default support dual vga cards (nvidia optimus) at this point.

I have the gt540m and had to do quite some searching on that.

I did my searching in december, and by the time, the only option available was to download a module and run some commands, so that you kill your high end card and only work on your low end, onboard card.

You can find details on that here: http://hybrid-graphics-linux.tuxfamily.org/index.php?title=Acpi_call

I searched a bit now to look for your answer, and looks like there have been a few developments in the topic in the past couple of months. A team was working on a project called bumblebee, designed to help ubuntu support optimus cards, and they seem to have released it. I found this tutorial on how to use it, but this is something I have not yet used myself/have no idea if it will mess my system up or not.

Long story short, your options are A: kill your card, work with onboard one, or B: try making your system compatible.

Hope this helps. Good luck.

acpi_call is deprecated because you won't survive suspend through it, i.e. the card stays on after suspend. Bumblebee as of version 3.0 provides excellent support for toggling the power on the discete card. See also askubuntu.com/q/36930/6969 –  Lekensteyn Feb 29 '12 at 11:05
    
please assist me here. I have the gt540m. do you think this could work? ivegotavirus.com/blog/2012/01/23/…. I plan on trying it on my system. –  AnPel Feb 29 '12 at 11:07
    
I guess so. The most reliable installation instructions can be found at bumblebee-project.org/install.html#Ubuntu (or the AU question that I've linked above) –  Lekensteyn Feb 29 '12 at 11:20
