Dmesg after first boot
Since kernel 4.7 (at least, see below), whenever I resume from hibernation and
try to use xrandr to manipulate any video output, my screen goes off and on
again and this message is displayed:
xrandr: Configure crtc X failed
With no effect happening, whatever the xrandr command I issued.
This has been confirmed in kernel 4.7, 4.8, 4.9 and 4.10-rc8 drm-tip that I've
just built now up to commit 890e171e84eb11944701de9d53c1162dd5c38142.
I can't recall exactly, but I'm pretty sure 4.6 has this issue, and MAYBE 4.5.
I am pretty sure however that 4.4 works just fine as I've been using that for a
long time.
This is the same issue described here, and already bisected in October last
year by another user:
<a href="https://lkml.org/lkml/2016/10/28/441">https://lkml.org/lkml/2016/10/28/441</a>
My hardware is a Lenovo X230 Ivy Bridge i5-3320m. Distro is Debian amd64, mix
of stable and testing.
I'm attaching the dmesg logs before and after hibernation using drm-tip and
drm.debug=0xf.</pre>
