I finally decided to give a shot to Garuda and finally getting rid of Windows on my desktop PC.
It seems I can't boot in either free or non-free drivers, the "automatic driver installation via MHWD" seems to take forever (10min+) for both options.
I'm using the KDE "Gaming" edition, as it's my desktop PC sole purpose. Here are my specs:
GPU: RTX 2080
any idea ?
