I tried them way back in January with no visible difference, flickering still appears after laptop panel turns off and back on.
Regarding dmesg, can you please tell me for which kernel you want to see it (intel-drm-next/vanilla), with those patches or without and which additional kernel debugging options should be enabled? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1522922 Title: Screen flickering in Intel i915 driver Status in Nouveau Xorg driver: Incomplete Status in xserver-xorg-video-intel package in Ubuntu: Triaged Bug description: There's an upstream bug reported here https://bugs.freedesktop.org/show_bug.cgi?id=91393 that causes screen flickering when using the Intel i915 builtin driver (at resolutions lower than the maximal one). I think that it will be fixed in newer kernel versions, but for the time being, as reported here https://bugs.freedesktop.org/show_bug.cgi?id=91393#c25 (and as personally tested) reverting those two commits fixes the problem. Would that be possible to release a fixed version for the 4.2.0 stream?
