Nvidia X Settings wont let me choose gpu??? [SOLVED]

[boy&hisdogs]

I'm running 17.1 and a gtx860m. In the Nividia X settings program (gui not terminal) the integrated graphics is selected by default and when i try to select my gtx card it asks for my password and even though authentication is successful a dialouge box pops up with a speech bubble containing an X and no message or error code. It does the same thing when i start the program as SU.

Any ideas?

I'm running 17.1

As far as i can judge it, you have a Hybrid system? Nvidia GTX GPU and an integrated Intel GPU? Did you installed the tool nvidia-prime?
If not, do this in a terminal:

First remove all Nvidia drivers installed:

Code: Select all

sudo apt-get purge libvdpau-va-gl1 bumblebee* nvidia*

Now install the driver again:

Code: Select all

apt-get install nvidia-*** nvidia-settings nvidia-prime

At the asterix you fill in the version number of the Nvidia driver you want to have installed.
As example:
If you want driver 349.x to be installed, fill in 349 for the asterix.

With the nvidia-prime tool you can select and switch between both GPU's:

To select the default GPU:
For intel:

Code: Select all

sudo prime-select intel

For Nvidia:

Code: Select all

sudo prime-select nvidia

With the code above you set the default GPU which will be used when turning on/logging in.

Switching between the GPU's:
When running with Nvidia GPU:

Code: Select all

sudo prime-switch intel

When running with Intel GPU:

Code: Select all

sudo prime-switch nvidia

After each switch or selection, reboot your system to make sure that the changes will have their effect.

With this command you can check which card is selected:

Code: Select all

sudo prime-select query

Good luck!

Woohoo! It worked perfectly! Thank you!

And yes, I have both. It's an Asus G750 laptop with both Intel integrated graphics and a Nvidia 860m card. I didn't have the prime tool, just the nvidia one I mentioned in the OP and the standard linux "driver manager". This tool is great! It couldn't be simpler.

First of all, Mint 17.1 is obsolete now if i'm not mistaken. Best is to upgrade to Mint 17.2.

Mint 17.1 is not obsolete. It's still supported until May, 2019 (just like 17 and 17.2).

I stand corrected! It still is supported.
