I am trying to get my laptop to use my Nvidia Geforce GT 640M GPU. When I look at the "Software & updates > Additional Drivers" panel it is completely empty. It looks like the problem is here:

ubuntu-drivers debug
=== log messages from detection ===
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-173 for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-173-updates for hybrid system
DEBUG:root:X.org log reports loaded intel driver, disabling driver nvidia-304 for hybrid system
...

The output of lshw (in case that helps):

How do I force X to ignore the Intel graphics and use the Nvida GPU instead?

What are the contents of xorg.conf? –  handuel Apr 10 '13 at 19:34
    
Err, I don't think Ubuntu has had one by default for a while now. I don't see one lurking in /etc... –  Mike Williamson Apr 10 '13 at 21:20
    
Ok, I was just checking, occasionally drivers try to generate their own and break things with them. –  handuel Apr 11 '13 at 6:38
    
I'm having this exact issue, did you ever find a resolution? –  Dan Hanly Apr 1 at 21:09
    
I have the same problem, I logged a bug: bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/… –  Noki Apr 26 at 16:24
