Ubuntu 20.04 NVidia X Server Settings only showing PRIME Profiles
Solution 1:
I had this problem and was not able to solve it even after a reinstall of Ubuntu 20.04. But the NVIDIA driver was working fine on Ubuntu 18.04 and pop OS 20.04.
I guessed the problem must due to the new feature in Ubuntu 20.04 where during the Ubuntu installer installs the NVIDIA driver during the installation of the OS. So, I reinstalled Ubuntu again on my system after unchecking the option to install third-party software for graphics and WiFi and additional media formats. Then I manually installed the NVIDIA driver post installation of Ubuntu using the GUI as I did for my 18.04 installation.
Now all the options in NVIDIA X server settings are displayed.
Since I am a newbie to Linux, I was not able to find why this error happened during installation.
