I tried installing Nvidia drivers using different ways: repository nvidia-current, nvidia-331 and using downloaded file from Nvidia web site. Installations seems to be successful, although I got pre-installation script failed message from .run file.

After installation I ran sudo nvidia-xconfig and reboot.

In both cases the system doesn't seem to use installed driver. Going to nvidia-settings gives an error:

You do not appear to be using NVIDIA X driver. Please edit you X configuration file (just run nvidia-xconfig as root), and restart the X server.

Running nvidia-smi give an error:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

lsmod command lists nvidia among other modules:

nvidia 10688804 0

So, I'm totally confused. How can I change that OS is using nvidia driver. How to get rid of error above?


My nvidia-settings opens now, but it has not much settings inside: enter image description here

In the command line I see the following error:

** (nvidia-settings:4334): WARNING **: PRIME: Failed to execute child process "/usr/bin/prime-supported" (No such file or directory)

** Message: PRIME: is it supported? no

The command inxi -Gx (whatever it does) gives me:

Graphics: Card: Intel 4th Gen Core Processor Integrated Graphics Controller bus-ID: 00:02.0 X.Org: 1.14.3 drivers: nouveau,intel (unloaded: nvidia,fbdev,vesa) Resolution: 1920x1080@60.0hz GLX Renderer: N/A GLX Version: N/A Direct Rendering: N/A

So I can conclude that nvidia driver is not used. How to fix it?
