After changing to Intel (Power Saving Mode), Nvidia X-server setting is not showing anything. I need to active GPU now but can't activate it.

$ sudo lshw -c display

I had this problem after a fresh Ubuntu 20.04 install.

Running sudo ubuntu-drivers autoinstall solved the issue.

I fixed this issue by installing another version of Nvidia driver. I am not sure about whether this error will appear again.

  • Which other version of the NVIDIA driver did you install? What commands did you use to install this other version? Did you remove the old NVIDIA driver? – Lexible Oct 31 '20 at 22:35
  • I removed all nvidia related driver previously installed. Then installed another version of nvidia driver from additional driver in software & updates. – Sayed Sohan Oct 31 '20 at 22:47
  • Thank you. How did you remove all previously installed nvidia-related drivers? – Lexible Oct 31 '20 at 22:59

  • @SayedSohan when i opened additional drivers in software & updates, it says no additional driver available – Israel Obanijesu Apr 12 '21 at 20:13
  • @IsraelObanijesu maybe your gpu isn't recognized.. try install gpu directly from nvidia website or reinstall os. – Sayed Sohan Apr 13 '21 at 06:59

    Ah, gave up on it already, all i wanted to do is change the overscan for my TV when using HDMI but it is not that important to the extent of reinstalling my os – Israel Obanijesu Apr 13 '21 at 07:03

You could have just changed the Nvidia setting via command line by using:

sudo prime-select nvidia

Then it would have gone back to Nvidia mode.

This solution worked for me (a problem linked to ubuntu-drivers-common package updating) :

Use this command to open the /usr/bin/prime-supported file:

xed admin:///usr/bin/prime-supported

Change this line:

if [ -e "/var/lib/ubuntu-drivers-common/requires_offloading" ]; then

To this:

if [ -e "/var/lib/ubuntu-drivers-common/requires_offloading" || true ]; then

Your graphics isn't recognized.

I just reinstalled OS and mark "install third party software".

After that, do not install any other graphic driver. You will run on Intel choosen by Ubuntu. Nothing other works like this solution.

PS: When you reinstall, you can choose in Nvidia x server settings " Power saving mode".

Hope it helps.
