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
  *-display

$ sudo nvidia-settings

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.

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.
