I recently switched from Windows to Ubuntu on PC and, as a longtime Windows user, I installed amdgpu-pro graphics from AMD's official site. However I'm experiencing problems with amdgpu-dkms crashing and realized there are mesa drivers that are, in opinion of most, better than amdgpu-pro.
So I want to install latest stable Mesa drivers on my PC and I read Ubuntu 20.04 comes with Mesa preinstalled but when i run

glxinfo | grep Mesa

I get no output. Does this mean that, since I installed amdgpu-pro, Mesa is blacklisted? I checked blacklisted modules but I didn't find Mesa among them.
Anyways, in browsing how should I go about replacing amdgpu-pro with mesa, I came across these 2 questions:

  1. How to uninstall AMDGPU?
  2. How to blacklist amdgpu driver?

I want to do this safely, so should I firstly install mesa, then blacklist amdgpu and then, if it all works run:

sudo amdgpu-pro-uninstall

If not, what are the steps of replacing amdgpu-pro with mesa and what is the safe way of deleting amdgpu-pro?

  • It means that, when I type "glxinfo | grep Mesa" in Terminal, Terminal doesn't output anything, just goes to next line as if Mesa doesn't exist. If i try "glxinfo | grep OpenGL" I get expected output
