** Description changed: Binary package hint: gnome-power-manager Toshiba satellite A210P with ATI graphic card, running Ubuntu 10.04 LTS kernel 2.6.31-10-rt (kernel 2.6.32 also affected). issue in gnome-power-manager 2.30.0-0ubuntu1 After installing omnibook module (for bluetooth) and proprietary ATI driver gnome-power-manager cannot read and change LCD brightness. The applet slider is stuck at the upper position. Brightness can only be changed by pressing Fn keys. In karmic, everything worked fine. The keys can be disabled by modprobe -r video. However, the situation with g-p-m remains. Blacklisting omnibook did not solve the issue. cat /proc/acpi/video/VGA/LCD/brightness - returns: + returns: levels: 0 10 20 30 40 50 60 70 current: 70 Trying to echo anything to /proc/acpi/video/VGA/LCD/brightness fails with access denied error, even as superuser. Dmesg after pressing Fn keys returns: [ 1802.062534] [fglrx:firegl_acpi_video_event] *ERROR* Could not find private acpi context by video busid: LCD [ 1813.759336] [fglrx:firegl_acpi_video_event] *ERROR* Could not find private acpi context by video busid: LCD [ 1813.773890] [fglrx:firegl_acpi_video_event] *ERROR* Could not find private acpi context by video busid: LCD [ 1813.783447] [fglrx:firegl_acpi_video_event] *ERROR* Could not find private acpi context by video busid: LCD [ 1814.933052] __ratelimit: 14 callbacks suppressed [ 1814.933063] ACPI: EC: missing confirmations, switch off interrupt mode.
