I had a similar problem (Bug #201933) but it was fixed. Maybe the fix interferes with your issue. If you still have the issue do the follow: The easiest way is to install apt-src and then the Intel driver source package with >>apt-src install xserver-xorg-video-intel<< . Afterwards go to the directory ./xserver-xorg-video-intel-2.2.1/debian/patches and remove the file 16_legacy_backlight_blc_pwn_ctl.patch and the entry from the file series in the same folder. Than go back to the xserver-xorg-video-intel-2.2.1 directory and create the package with >>fakeroot dpkg-buildpackage<<. If it is completed just install the created Driver package with dpkg or a double click. After X restart check if the problem is gone.
