Almost of time the screen turns grey colors and stops flickering. Then,
I have to try change screen resolution many times until colors are back,
and the flickering.
I have tried several screen resolutions and frequencies, including the
configuration that works fine with graphic Gallium 0.4 on llvmpipe (LLVM
3.6, 256 bits), that I got when I boot in recovery mode, choose
failsafeX and I stop the process with CTRL+C just after the X error.

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?
