** Description changed: Binary package hint: gnome-power-manager With the deprecation of hal, gnome-power-manager must rely on the BACKLIGHT property in xrandr; however, the ATI open-source drivers seem not to support this property (regardless of whether KMS is enabled). With HAL removed, g-p-m does not offer brightness controls at all. Additionally, even if I reinstall HAL, the backlight control still does not work -- upon pressing the brightness control keys, notify-OSD shows the slider at a fixed value, but the slider does not move. I have attached (originally to bug 38057915 ) a log of gnome-power- manager --verbose: http://launchpadlibrarian.net/38057915/g-p-m.log -- Note that gnome-power-manager seems to be repeatedly setting the same brightness level with each keypress. The Gnome brightness panel applet also behaves strangely: sometimes it works, and sometimes it displays "Cannot get laptop panel brightness". I am using Lucid with xorg-edgers, currently booted into kernel-ppa 2.6.33, but this issue also occurs with normal Lucid packages.
