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? Apr 10, 2013 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... Apr 10, 2013 at 21:20
  • Ok, I was just checking, occasionally drivers try to generate their own and break things with them. Apr 11, 2013 at 6:38
  • I'm having this exact issue, did you ever find a resolution?

  • I have the same problem, I logged a bug: bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/…
