01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 940M] (rev a2)

nvidia-settings

Re: [Solved] Can't get my nvidia card to work

nvidia-xconfig does not work with Hybrid_graphics, follow the NVIDIA Optimus or Bumblebee guides linked from that article.
If you installed the nvidia drivers directly from the nvidia website you will want to remove those first.

Don't use  xconfig: it just breaks things. Read the wiki entry on Optimus.

What commands did you run before you reached that step in the optimus guide?
What were the outputs of those commands?
What xorg.conf did you use?
Please also post your xorg.log that running X now generates.
Why did you run that command with sudo?

Don't randomly decide to use sudo, it is not a magic "make everything awesome" command.

Re: [Solved] Can't get my nvidia card to work

I used sudo because it wouldn't give me an output otherwise, i seemed to have fixed the problem by going through the whole process again.
I must have forgotten something.

Thanks for telling me to use Optimus, that seemed to have fixed my problem.
