I've encountered this issue with kernel 5.2 (tried 5.2.8 just now) and also
have a Ryzen 5 2500U notebook (Huawei Matebook D 14" (AMD)). Running Manjaro.
The login screen appears fine, but after that, black screen. I know nothing's
locked up because I was able to launch GZDoom from typing in the dark in the
whisker menu and heard the sounds of Doom, or at least the title screen.
