Hi, when I suspend/resume, the display driver (i915 in gentoo-sources-3.8.4 or xf86-video-intel-2.20.13) sets the backlight state to off. The extended function keys (fn + brightness-up) work so I can get a proper display. Reproducible: Always Steps to Reproduce: 1. have a hybrid graphics laptop (here: Core i5-2430M and amd/ati HD6470M in a HP "Pavilion g6 1222sg" laptop) 2. install Gentoo Linux 3. use gentoo-sources-3.8.4, xf86-video-intel-2.20.13 with USE="-sna uxa" and ati-drivers-3.13_beta2 4. boot 5. let "udev process events", see the backlight being turned off (re-enable with fn+brightnessUp), wait for the X display to appear, log in 6. suspend+resume Actual Results: the display backlight is turned off Expected Results: the display should be a bright as before suspending lapmdb-hpl ~ #>>

Created attachment 343740 [details] kernel .config for gentoo-sources-3.8.4
might be a fault in xf86-video-intel-2.20.13, too...
Try 3.8.5, it contains Revert "drm/i915: write backlight harder"
3.8.5 will soon be in the Portage tree. Please let us know whether that one works.
(In reply to comment #4) > 3.8.5 will soon be in the Portage tree. > > Please let us know whether that one works. Yes, gentoo-sources-3.8.5 correctly sets the brightness to values as before suspend/resume. Tried with brightness=max and brightness=min(off+1), both worked correctly in suspend/resume. Setting Status to resolved/fixed.
