[arch-general] amdgpu: blank screen on Radeon RX 460
Hi, since some updates in the last days - I have not found out yet which one caused it - my Radeon RX 460[1] only shows a blank screen after starting lightdm and also switching to terminal is not possible. As a workaround booting with "amdgpu.dc=0" helps - but then audio via HDMI is broken. The issue appeared once some months ago, but after wondering why audio is broken I removed "amdgpu.dc=0" and everything went smooth - until now. I've searched through the BBS and amdgpu bugreports, tested some kernel commandline parameters like amdgpu.gpu_recovery=1, switching to DRI "2", but no solution yet. Does somebody else have a similar gpu and experiences a similar issue? Best regards Bjoern [1] 07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

sometimes checking "too simple" things could fix issues. The issue was caused by a loose connection of the HDMI cable. But somehow strange IMHO that it still worked with amdgpu.dc=0 and on Win10. Best regards Bjoern
