I installed my GPU two months ago in my computer and everything worked fine. All of a sudden, I noticed in the "Details" page from "System settings" that my GPU is not working anymore; I make sure it didn't work when I tried to play a game that I used to play when the GPU was working.

Anyways, I tried to install the GPU again, the same way I did before, using this page: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia

when I go to "additional drivers", I find my GPU there, but when I go to the "Details" page is not there in the "Graphics". Also, the GPU is not working when I play any game that needs the GPU to work well. Any Ideas how to fix it?

It looks like the GPU is installed but not working.

When I try to use "sudo nvidia-settings" I can't choose NVIDIA.

UPDATE:

This is the additional drivers, where it shows my Nvidia 352 that I want to use. enter image description here

But here (In details page), the Nvidia is not shown; so I can't use it:

  • How did you install the graphics driver. If you used run files, then you will have to re-install the driver after each kernel update.

Possible fix:

1.'sudo apt-get remove --purge nvidia-settings'

  1. 'whereis nvidia-settings'

  2. Delete everything listed. Because of a "feature" in Linux the system thinks that your going to need these files again. What is happening is thst you config files are not removed.

NOTE TO DEVELOPERS - Purge means remove EVERYTHING including the config files

  1. Then reinstall the driver per instructions.

This is the simplest way, that I found, to cure most configuration problems.

  • I tried this, but still I'm having the same problem. I'm using "Wine" and "PlayOnLinux" maybe that affect it?
