Cant change resolution

(1/1)

Mel_B:
When I try to change resolution the screen tears and is all garbled. Here is my INXI I am sure it is a driver. I have had this problem with debian not detecting my Built in the cpu graphics. A non free firmware solved the problem. I do not have this problem with Ubuntu or mint.

That was very helpful! I can confirm that adding
AMD_DEBUG=nodmacopyimage
to /etc/environment fixes the problem on Ubuntu 20.04.

Or, try installing, reverting video drivers.
