Unfortunately, while I was able to complete the install of Kubuntu 20.04, I was NOT able to boot into it. The computer hangs booting into that version every time.
It does not have a problem with 21.04 or 21.10, however.
Nor some other distros (like Garuda dragonized kde)…
I’m at a loss… I try to install AMDGPU-PRO drivers, but that fails because I’m on the wrong version of OS. Guess I’ll be keeping WInders for video editing. A shame, if you ask me…
