--- Comment #5 from Patricio Villar <patovm04@gmail.com> ---
13.0-RC2 and RC3 were nearly flawless and this issue became really hard to =
see.
Unfortunately, 13.0-RC4 brought a big regression in this regard. It now hap=
pens
most of the time!

At least, I think I was able to understand a little bit more:
When resuming, if I see this console message: "drmn0: Failed to idle engine=
s,
declaring wedged!" then it completely fails to resume X.

Whereas, when the above line doesn't appear and this other line still shows:
"i915 raw-wakerefs=3D3 wakelocks=3D3 on cleanup" then it looks like all is =
fine for
a few seconds, but after a while, Xorg is killed and restarted all of a sud=
den
and I'm right back at my display manager (SDDM).

Any ideas?
