Description of problem: In gnome, when you press the brightness control keys, it displays the icon that shows the brightness level change and modify the values of / proc/acpi/video/GFX0/DD02/brightness Example: $ cat / proc/acpi/video/GFX0/DD02/brightness Levels: 10 20 30 40 50 60 70 80 90 100 current: 10 $ cat / proc/acpi/video/GFX0/DD02/brightness Levels: 10 20 30 40 50 60 70 80 90 100 current: 100 Version-Release number of selected component (if applicable): Fedora 13, kernel 2.6.33.6-147.fc13.x86_64 SMP acpid-1.0.10-2.fc12.x86_64 How reproducible: The problem is permanent. You can not change the brightness of the screen. Steps to Reproduce: 1. just install fedora 13 on Intel core i5 with new HD graphics video controller 2. 3. Actual results: Expected results: make the brightness control keys work properly, allowing to save battery power Additional info: The hardware of my laptop is Acer Aspire 4741-6628 with Intel i5-430M and "Intel HD graphics"
This is unlikely to be related in any way to the acpid. acpid is disabled when running GNOME. More likely there's a driver issue.
You're right, gnome works with gnome-power-manager and HAL. Maybe it's a driver problem, although I have no problem with the graphics. Convinces me more the idea that is related to power management. I'll pass this error in gnome-power-management. Thank you.
Hello everyone, I tried the following: $ cat /sys/devices/virtual/backlight/acpi_video0/brightness 9 $ cat /sys/devices/virtual/backlight/acpi_video0/brightness 0 Function keys for brightness control changes the values, but the brightness level does not change.

This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
