Description of problem: Hardware - Laptop HP EliteBook 8530w clean install F15 and update to 20110729 the backlight apparently works ok (even the "auto light sensor icon seems to look exactly the same as touchpad) but after forced to hibernating or forced to suspend (or wait until power manager sent to any of this states) brightness of display is around 25% and controls don't work at all (FN + F9/F10/F11) also autodim sensor seems to don't work tried to force with pkexec gnome-power-backlight-helper --set-brightness 1~24 - no visual improvements - values over 25 gives the error " Could not set the value of backlight: writting '25' to /sys/class/backlight/acpi_video0/brightness failed" Version-Release number of selected component (if applicable): FC 15 Linux 2.6.38.8-35.fc15.x86_64 gnome-power-manager version 3.0.0.-3.fc15 How reproducible: each time laptop enter in one of suspend or hibernate state Steps to Reproduce: 1. boot 2. wait until any state (suspend / hibernate) occur or force suspend or hibenrate 3. push power button Actual results: diplay brightness is les than half and no way to control it via any buttons commands Expected results: display should remain at the previous state + user should have control via built in buttons (FN + F9,10,11) Additional info:
It does the same bad behavior if I close the lid of my laptop even after the boot reboot computer - everything seems ok login screen appear - but instead to log in I close the lid and the open it back - this is due to fact close lid will force to suspend - BUT I HAVE chosen not to do so.?!?!?! (by gnome-tweak ) then the screen is dimmed and not able to change the same procedure but after reboot logged into my account - close the lid - laptop is forced to suspend - after power up display is dimmed and no control on it the same procedure but after reboot logged into my account - prior to everything changing lid action to blank (even by installing gnome-tweak even from command line with gssetitngs) seems to change behavior - laptop will no more be forced to suspend - this remain ok after reboot EXCEPT the moment before login
it has the same behavior on Fedora 16 latest upgrade upgraded using PreUpgrade from 15
Same bug in Fedora 16(fresh install). gnome-power-manager-3.2.1-1.fc16.x86_64
Hey guys, Could the problem appears because of this: [root@fedora16 cron.hourly]# pkexec /usr/libexec/gsd-backlight-helper --set-brightness 24 The value for the SHELL variable was not found the /etc/shells file This incident has been reported. -------------------------------------------------------------------------------- [root@fedora16 cron.hourly]# cat /etc/shells /sbin/nologin /bin/dash -------------------------------------------------------------------------------- Cheers

Only with the nouveau driver (Nvidia doesn't have this bug). The command above works, if i suspend, it does not work anymore. the only way to restore brithness is to reboot. $ cat /sys/class/backlight/acpi_video0/max_brightness 24 $ cat /sys/class/backlight/acpi_video0/actual_brightness 24 $ cat /sys/class/backlight/acpi_video0/bl_power 0 $ cat /sys/class/backlight/acpi_video0/brightness 24 I tried to set bl_power to 1, but no effect.
[Mass hibernate bug update] Dave Airlied has found an issue causing some corruption in the i915 fbdev after a resume from hibernate. I have included his patch in this scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=3940545 This will probably not solve all of the issues being tracked at the moment, but it is worth testing when the build completes. If this seems to clear up the issues you see with hibernate, please report your results in the bug.
Is this issue still being seen with the 3.3 update?
Nope, the issue is resolved in 3.3. Well sometimes in order to get the brightnes to the previous state I need to hold down the FN key and the brightnes up/down button.Anyway IMHO the issue is gone.
Thanks for letting us know.
I still have the issue on Fedora 17 with kernel 3.3.7-1.fc17.x86_64 backlight is off after suspend and hibernate.
I can confirm also 3.4.0-1.fc17.x86_64 the bug is present not yet solved
Hey guys, I have tested a couple of consecutive suspends/hibernates and every time I seem to fix the brightness level by pressing FN key and the brightnes up/down button or FN brightnesses button. Some more info about my EliteBook 8530 Video:ATI 5700 Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz uname -a Linux unknown 3.3.8-1.fc16.x86_64 #1 SMP Mon Jun 4 20:49:02 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Is this still an issue with 3.6.9 kernels?
Hey Justin, I just installed and configured Fedora 18 on my EliteBook 8530w(ATI 5700 Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz) and the issue is gone. $ uname -a Linux localhost.localdomain 3.6.9-4.fc18.x86_64 #1 SMP Tue Dec 4 14:12:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux IMHO this could be closed.
