Also, does the DVI output gets back when you run xrandr manually again, e.g. like xrandr --output DVI-1 --off xrandr --output DVI-1 --auto ? (the output name must match with the actual one) Last but not least, boot 4.1 kernel with drm.debug=0x0e option, do suspend/resume and give the full dmesg output to bugzilla. This will contain verbose logs of i915 driver. -- You are receiving this mail because: You are on the CC list for the bug.

Then this has to be cared by upstream. The log doesn't look good, there seems multiple bugs there behind the scene... Could you report this to the upstream bugzilla (either bugzilla.freedesktop.org or bugzilla.kernel.org) and provide the information there?

With 4.6 it finally works. With Leap 42.2 kernel it does not.
