Hello there
On kernels 5.3.1 and 5.4.0-rc1, I get a black screen with a white underscore cursor in the upper left. The display gets stuck in this state, with no way to switch to a different TTY or leave this aside from hitting the reset button. I can secure-shell into the box and get a login at this time, but killing the process does not fix the display. Sway WM also does this, with it just getting stuck at the prompt entry.
I have an AMD RX 5700 graphics card, using the amdgpu driver. When I do some manual configuration by blacklisting amdgpu and writing a stanza in xorg conf for vesa, I am able to get X running using vesa.
