My laptop (core m5-6y54) starts flickering after returning from Suspend (to RAM) or other commands touching the video driver (xrandr ...)
From kernel (tested with up to 5.7) I get the message:
[drm:intel_
I added a bug with more details here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872760
but guys from Ubuntu seems not able to help.
This happend not in older kernels, but these have the problem not to go in power save states. So I think the fix of that
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863489
causes this regression.
Hope someone can help. For a laptop it is better to have both - standby and power saving. Thank you.
