--- Comment #7 from Victor NOEL <victor.noel at gmail.com> ---
Currently (with xf86-video-intel 1:2.99.917+478+gdf72bc5-2 on archlinux) and
xorg 1.17.4, I still have some issues but it is not as terrible as before.

Basically, when I start the computer again, my laptop screen is black and my
external screen is all scrambled (as if the resolution was too big and I could
see just a quarter of it, and there is lines missing and it's terribly ugly).
I just need to unplug the external screen and replug it to get back a normal
image, and then I can login, continue my previous session and everything works
as it should.

There is these errors in the logs:
