well, eventually means it could take halve a year until we got those patches which makes our computers useless. I can also add that on my computer I cannot enable vesa mode and i915.modeset=0 option makes the screen black, i.e. bricks it. Reverting two patches for the ubuntu's 4.2.0.19 kernel like it was described above doesn't help either. I tried to figure out how to apply your patch onto 4.2.0.19 but it seems like training staff was moved out of the intel_dp.c and some files are missing completely, so no luck. Cloning the 1Gigabyte git repo like you suggest would also mean that I'd need to compile drm driver code with the kernel version that in that repo too right? Or I can copy the gpu/drm/i915 over to my kernel version and it'll work? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1522922 Title: Screen flickering in Intel i915 driver Status in Nouveau Xorg driver: Incomplete Status in libdrm package in Ubuntu: Confirmed 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?
