This patch resolves the issue, but to be precise we should also set /org/freedesktop/Hal/devices/dell_lcd_panel: laptop_panel.brightness_in_hardware = true in hal-info(?). To do it manually: sudo hal-set-property --udi '/org/freedesktop/Hal/devices/dell_lcd_panel' --key laptop_panel.brightness_in_hardware --bool true
However SetBrightness does not seem to work on this model anyway, so it does nothing. This means dim on idle/dim on battery does not work. GetBrightness does work. Can one of the hal maintainers have a look at this patch? ** Changed in: hal (Ubuntu) Assignee: harrydb (harrydeboer) => (unassigned) Status: In Progress => Fix Committed -- [Hardy]Status of display brightness freezes g-p-m (or even X) for a while https://bugs.launchpad.net/bugs/176687 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
