Public bug reported: Binary package hint: gnome-power-manager
I've got an HP ProBook 4720s with the latest gnome-power-manager installed (lucid). I've got the following problems: - the brightness up/down buttons have no effect - the brightness adjustment applet has no effect and does not correctly display the current brightness - the brightness adjustment on ac power online/offline events does not work. I believe that the problem lies in the actual adjustment of brightness and not in the correct recognition of the hardware event: - I can manually read and adjust brightness by reading/writing from/to /proc/acpi/video/DGFX/LCD/brightness. - I can attach a script to the brightness up/down key events via Gnome Keyboard Shortcuts - I get a correct HAL event via halevt daemon - I get a correct key name mapping when looking at proc/input/event8 via keymap - I don't get an output when running gnome-power-manager in verbose mode and pressing the brightness up/down keys Unfortunately I'm not a HAL/udev/acpi specialist. I've tried to track this problem down as far as I could. But now I'm stuck. Anything more I can do for you to find/fix the root cause of the problem? ** Affects: gnome-power-manager (Ubuntu) Importance: Undecided Status: New -- Brightness adjustment doesn't work for HP ProBook 4720s https://bugs.launchpad.net/bugs/592592 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
