NVIDIA GK107M [GeForce GT 640M] proprietary OpenGL vendor

[Zach_Follette]

Hi all, I am posting because of a little problem I am having with my NVIDIA and Intel cards.

Here is my 'Additional Drivers' screen showing that I am using the correct nVidia proprietary driver.

But when I run the command

glxinfo | grep vendor

I get this output:

server glx vendor string: SGI
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: Intel Open Source Technology Center

I am not too sure what the 'server' and 'client' are, but I am wondering how to switch my OpenGL vendor to NVIDIA

Is this an optimus card? where you choose either Intel or Nvidia?

if so you may want to try nividia prime
See here for info:

or bumblebee - see here

Yes, it is an Optimus. I think I'll try prime because I was having some problems with bumblebee in Fedora 20. If prime fails, I'll look into bumblebee again, since Fedora and Xubuntu are completely different.

EDIT: Wow, thanks a lot.

glxinfo | grep vendor

now returns:

server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

I used prime, if you're wondering.
