Public bug reported:
When power management turns of the screen, and I wake it I get a garbled
screen. There's a divider in the middle and green streaks from the right margin
and the middle divider over the garbled background image.
I am able to login blindly, and removing and inserting the HDMI lead
restores the image. I also have a shellscript that I can activate with a
keyboard shortcut that users xrandr to turn the output off, wait two
seconds and turn i on again and that also restores the image.
AMD 7840U with built in Radeon 780.
I have tried increasing VRAM memory to 2 GB.
I tried adding "amdgpu.sg_display=0" to the boot parameters to no avail.
What can I do to help debug this problem?
I have the same CPU/GPU combo in my T14s laptop, but haven't got the
problem there.
Added a picture of the garbled display as attachment
