I have a 5700XT. I installed the official drivers from AMD. After that my screen started flickering. I uninstalled the drivers using the uninstall script ./amdgpu-install --uninstall, but the flickering persists. It would seem to me that the uninstall script did not actually revert everything to how it was before the driver installation.

  1. Create a directory sudo mkdir -p /etc/X11/xorg.conf.d/
  2. Create a file 20-radeon.conf within that, sudo nano /etc/X11/xorg.conf.d/20-radeon.conf
  3. Write

Save the file and then reboot

Hope this helps

    This fixes screen tearing but doesn't help with screen flickering.

I also used the amd 5700xt TUF OC 8Gb with Ubuntu 20.04.

Using the terminal I installed all open variant, because of some needed parts from AMDGPU-PRO packs (for example: OpenCL).

I have no problems with the Installation. I play in Steam (Linux) Dying_light, Doom, Dirt Rally 4 or the newer 2.0, with nearby 200 Fps. A great Vulkan Support from this Card.

I search a graphical xserver_app for amdgpu settings. The Adrenalin Software in MS Windows IS AWESOME. Here is the terminal command I used:

./amdgpu-pro-install -y --opencl=pal,legacy

A temporary fix is to run this command:

xrandr --output DisplayPort-1 --mode 1024x768; sleep 1; xrandr --output DisplayPort-1 --mode 2560x1440 -r 120

Replace the 2560x1440 -r 120 with your own resolution and refresh rate. This will stop the flickering immediately, but it will probably resume when you reboot or wake from sleep.
