| |
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).
regards, dan carpenter
