--- Comment #18 from Ander Conselvan de Oliveira <conselvan2 at gmail.com> ---
Looking at your dmesg, it seems X turns off all CRTCs (which is normal
behavior).  The odd part is that after that no CRTCs are turned on.

Could you try the latest xorg driver from
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ ? If that still
doesn't work, could you compile the driver with --debug=full and attach your
Xorg.log again.
