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.
