Patrick Schaaf has reported that the i915 driver is setting his
backlight very dim when he starts GDM.

https://bugzilla.kernel.org/show_bug.cgi?id=23472

It should be the dell-laptop platform driver controlling his backlight.

Gnome tries to restore the backlight settings through the dell_laptop
interface in sysfs but it fails.  (Because the platform hardware refuses
to set the settings to what it thinks they already are).

dan carpenter
