Version: guidance-power-manager-4.1.3-1.fc10.x86_64 (using KDE 4.1.3) OS: Linux Installed from: Fedora RPMs Description of problem: I am not able to adjust my screen brightness. I have configured brightness levels for ac and battery but they do not seem to work. Though when i leave my laptop and it turns off LCD as i have that in power management it changes brightness to some low level and i am not able to change that back. It acts really strange because it sometimes changes brightness with no reason. My function keys to adjust brightness do not work either. Version-Release number of selected component (if applicable): kernel: 2.6.27.5-117.fc10.x86_64 xorg: xorg-x11-server-Xorg-1.5.3-5.fc10.x86_64 guidance-power-manager: guidance-power-manager-4.1.3-1.fc10.x86_64 Laptop is Compaq 6720s, Intel X3100 graphic. How reproducible: Every time i use my laptop Actual results: Does not work Expected results: Should adjust brightness level
I have a similar problem with a Lenovo T60 laptop and Fedora 10 x86_64: the brightness keys (Fn+Home for brightness up, Fn+End for brightness down) do not work. Using acpi_listen, I see these keys generate video LCD0 00000086 00000000 video LCD0 00000087 00000000 for brightness up and down respectively. And using xev, I see Fn+Home = keycode 233 = XF86MonBrightnessUp FN+End = keycode 232 = XF86MonBrightnessDown Guidance Power Manager doesn't seem to know what to do with XF86MonBrightnessUp and XF86MonBrightnessDown keys, so I remapped them to F21 and F22 using xmodmap. xmodmap -e 'keycode 233 = F21' xmodmap -e 'keycode 232 = F22' I then went to KDE4's System Settings -> Keyboard & Mouse -> Keyboard Shortcuts and under the "KDE Component: Guidance Power Manager" I changed Brightness Up to F21 and Brightness Down to F22. Now I can change the brightness with Fn+Home and Fn+End.
Same happens in my Toshiba Laptop. System won't apply brightness policy when reboot, although it does apply to CPU frequency. When I open Guidance Power Manager main window, I can see the slider control to the minimum. If I even touch it, the system realizes that it must low down display brightness, and it applies my policy. Otherwise, I does nothing about it.

Trivial patch submitted for 173146 which should help with saving brightness settings. Doesn't do anything about function buttons for brightness.
