[Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver

[Pietrek B.]

Apologies for spamming, guys.

I tried another fix for this bug, as suggested here: https://gitlab.freedesktop.org/drm/amd/-/issues/695#note_313722
and it seems to be working.

I rebuilt the xserver-xorg-video-amdgpu-hwe-18.04_19.0.1 package with
https://github.com/freedesktop/xorg-xf86-video-
amdgpu/commit/a2b32e72fdaff3007a79b84929997d8176c2d512 reverted and my
machine is able to resume from suspend/hibernate just fine while keeping
both DRI3 and KWin's OpenGL compositing enabled.

Here's the deb for you to test: https://drive.google.com/file/d/1AK-

Note that this is for 18.04 and you have to have the HWE stack enabled
first: apt-get install --install-recommends linux-generic-hwe-18.04
xserver-xorg-hwe-18.04
