If I suspend the laptop then on resume the GPU does not work. I've tried w=
ith
a 5.0 and a 5.2 kernel, same issue. dc=3D0 or dc=3D1 doesn't make any obvi=
ous
difference. I have gpu recovery enabled, otherwise it really hangs. With
Xorg, the screen looks the same as when suspended. With Wayland, there is
bunch of garbage around. In both cases, the mouse moves around, but there =
are
no screen updates. The following output shows up in dmesg with the last li=
ne
repeating endlessly, probably correlated with screen update attempts:
