xorg log
Hi,
I'm using a Ryzen 3550H laptop with integrated Vega graphics and an additional
Radeon 560. Whenever I boot the laptop with a screen connected to the HDMI
port, the screen turns blank upon lxdm start and I can see these error messages
in the Xorg log:
[ 263.699] (II) AMDGPU(0): Setting screen physical size to 1524 x 571
[ 263.716] (EE) AMDGPU(0): failed to set mode: Cannot allocate memory
[ 263.716] (WW) AMDGPU(0): Failed to set mode on CRTC 0
[ 263.817] (EE) AMDGPU(0): failed to set mode: Cannot allocate memory
[ 263.817] (WW) AMDGPU(0): Failed to set mode on CRTC 1
[ 263.887] (EE) AMDGPU(0): Failed to enable any CRTC
Kernel: is a self-built 5.0.9, but the same has happened with debian
experimental 5.0.2, as well as the debian buster's 4.19.
xserver-xorg-video-amdgpu: 19.0.1-1
If HDMI is not connected, everything is working.
