Try to update Intel driver.
For the persons that have the same problem.
I try xserver-xorg-video-intel of sid.
I add this line in my sources.list
deb http://http.debian.net/debian jessie-backports main
I update my driver with this line
apt-get install -t jessie-backports xserver-xorg-video-intel
I set my xorg.conf that aticonfig created in /etc/X11 and reboot.
And it work very nice ^^
Thanks everyone for your help.
