Title:
AMD RX 570 Black Screen at boot
Status in xserver-xorg-video-amdgpu package in Ubuntu:
Confirmed
Bug description:
Ubuntu 19.04
Problem:
Booting from live media OR installed ubuntu fails with a blank, black screen
and total system hang.
How to reproduce:
Using AMDGpu driver and AMD 4th Gen GCN GPU, try to boot Ubuntu 19.04 (or
18.04)
Resolution:
Manually updating kernel to 5.1 and adding the "amdgpu.dc=0" kernel boot
parameter seems to fix the problem.
