Created attachment 129647 [details] 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: https://lkml.org/lkml/2016/10/28/441 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.

Let me know if you want me to bisect it again.
