I am also affected by this problem. HP Pavilion DV6 2160eh (Nvidia GeForce G105M) Ubuntu 10.10 Maverick
It used to work fine (in 9.10). Maybe because of control keys are swapped... (https://bugs.launchpad.net/ubuntu/+source/udev/+bug/638638) I can change brightness by set manually in CLI as root which are working fine: #in this case brightness applet gets the new percentage as well (better): acpi_fakekey 224 #bright down by 10% (exec it more times result darker) acpi_fakekey 225 #bright up by 10% (exec it more times result lighter) or #setting this parameter manually does not have an effect on brightness applet cat /proc/acpi/video/VGA1/LCD/brightness # show current values and ranges BRIGHT="50" #values could be: 0-100 echo "$BRIGHT" > /proc/acpi/video/VGA1/LCD/brightness If I set manually the brightness to 50 and I start acpi_listen, then check brightness current parameter in case of keypress # FN+F7 (bright down key): video LCD 00000087 00000000 - results: current=0 and LCD brightness lighting as maximum until some of the acpi events (eg. power management changes) - pressing more times results nothing else # FN+F8 (bright up key): video LCD 00000086 00000000 - results: current=10 and brightness goes to that level (10%) - pressing more times results: it is trying to be lighter but after releasing goes back to 10% ** Changed in: gnome-power-manager (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. https://bugs.launchpad.net/bugs/566134 Title: brightness-applet behaviour is good -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
