[SOLVED] Radeon R7 screen flicker after resume from suspend

I am not sure after which kernel update started occurring but it must have been a couple of month ago. My system used to wake up from sleep without a problem. However now I get weird horizontal flickers on the screen. Not straight after the resume, about a second or two afterwards.

the (I think) important part of dmesg after the reboot:

Re: [SOLVED] Radeon R7 screen flicker after resume from suspend

As with most problems of this nature, if you don't rely on HDMI audio, try disabling the dc code, add

amdgpu.dc=0

to your kernel params

Re: [SOLVED] Radeon R7 screen flicker after resume from suspend

I do not use audio over HDMI. I'll try your solution later. I'll let you know how I got on.

Re: [SOLVED] Radeon R7 screen flicker after resume from suspend

Unfortunatelly setting the kernel parameter did not help. However...what I have just notices is that opening

pavucontrol

stops the flickering. The moment I close the Volume Control panel the flickering starts again! Isnt that just wierd?

Re: [SOLVED] Radeon R7 screen flicker after resume from suspend

Not really no, but it might provide a hint, your card tries to enable some power saving feature leading to the flicker, opening pavucontrol forces the audio output to wake up and the power saving to be deactivated. Do

amdgpu.aspm=0 amdgpu.runpm=0

or even just amdgpu.dpm=1 cause a difference.

Re: [SOLVED] Radeon R7 screen flicker after resume from suspend

I ran some tests this morning and

amdgpu.aspm=0 amdgpu.runpm=0

surely did the trick. Thank you very much for you help.

amdgpu.dpm=1

works as well, but my fan goes crazy.
