How to Fix NVIDIA X Server Settings Only Showing Prime Profiles on Ubuntu - So yesterday I encountered an issue about the Nvidia drivers, which resulted in screen glitch and missing options when trying to open Nvidia X Server Settings from the Ubuntu dash (I'm still using Unity desktop).

I decided to make this tutorial, in case you run into the same issue. Anyway, I'm using Ubuntu 18.04 LTS with latest Nvidia drivers right now. But, this issue also reported by some Ubuntu 20.04 LTS and Linux Mint users.

Well, here's the screenshot. It only showing showing prime profiles with performance mode selected.

NVIDIA X Server Settings Linux Prime Profiles Only

There should be more menus right here, including X server information, display configuration, open GL settings, antialiasing, VDPAU information, thermal settings, HDMI, PowerMizer, application profiles, and so on.

Nvidia system management interface program loads correctly if I run nvidia-smi via command line.

Let me show you the interesting thing. I'm gonna open System Setting > Details > Overview. As you can see, it tells a different story. My bionic beaver is currently running on Intel UHD 630, instead of my GTX 1050Ti.

Intel UHD Ubuntu Instead of Nvidia

I suspect this is happening because of the intel configuration that used as workaround to fix screen brightness issue on Linux.

This file contains the following lines :

Section "Device",
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"

So, I'm gonna try to detele or move it another folder to prove my guess.

sudo mv /usr/share/X11/xorg.conf.d/20-intel.conf ~/Downloads/

Once removed. Now reboot the system and the Nvidia graphics card drivers is finally loaded properly as shown in the video below :

Nvidia X Server Settings options will be back. So, these were all I can share. Hope this tutorial helped you to fix the problem of Nvidia X server settings on Ubuntu. Thanks for reading.
