Bug Description
After updating from 14.04 to 16.04 xenial, I am experiencing a screen flickering issue. The screen periodically completely blanks out. I tried the following kernels:
4.10.0 (daily from 1/30/2017)
4.4.0-59 (ships with 16.04)
4.1.21 (recommended from another random thread)
All with the same problem. Possibly related is this error from dmesg:
[ 5.138438] [drm:intel_
[ 5.141129] [drm:intel_
[ 5.343585] [drm:intel_
I also tried the following kernel options:
i915_enable_fbc=0
i915_enable_rc6=0
I installed and ran the Intel graphics update tool as well. The issue occurs on a X1 Carbon (3rd gen) laptop and only with an external monitor plugged into mDisplayPort at the maximum resolution (4k). If the resolution is lowered from the max, the flickering goes away.
Any help would be greatly appreciated.
