It seems since I installed the group of patches that came out with kernel 2.6.35.13-91.fc14.i686 I am no longer able to reproduce the problem. It seems to have been fixed with one of those patches. This is the set that was applied:

Throwing into approximate direction, please, reassign as appropriate. (was 0xFFFF) -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Please check actual_brightness, brightness, max_brightness in /sys/devices/virtual/backlight/acpi_video0 before suspend and after resume. Is there difference in content? Also try to set the brightness by hand by executing e.g.: # echo 9 > /sys/devices/virtual/backlight/acpi_video0/brightness Where the number 9 is from the interval 0 - max_brightness. Are you able to restore the brightness by this method? As you requested, I checked the actual_brightness, brightness, and max_brightness before, during and after. They are all 15 every time. They never vary, even when the screen dims. As you also suggested, If I run: echo 15 > /sys/devices/virtual/backlight/acpi_video0/brightness, the screen brightness returns. Thanks, now I at least have a workaround, and it sounds like you are on the right track. Thanks for info, it looks like kernel issue. Please provide output of: # pm-utils-bugreport-info.sh I will decide from its content. Created attachment 498654 [details]
Output from pm-utils-bugreport-info.sh
Thank. Please could you retest with F15 (e.g. from liveCD/USB)?
