Bug Description

Binary package hint: acpi

All worked on hardy.

On Intrepid when i try to scroll brightness-applet icon with mouse, brightness is changing correctly, but when i click the icon, the center of icon changes to red "disabled" mark and i can change brightness with moving bar up and down and 'scrolling the icon'.

If i will not click the icon it stays normal. When mouse is over icon, there is notification "cannot get laptop panel brightness" (but in hardy it was showing brightness level in % correctly).

Changing brightness with fn + F* keys works ok.

I saw this bug first in alpha4 then alhpa5 and every time since 8.10 was released. I haven't try to use 9.04 yet.

Laptop config:
Comal FL90
Graphics: nvidia 8600m GT (driver 177)
and c2d t7500, 2gb ram etc.

Also, I noticed this is a function of the Gnome Power Manager - Power Manager Brightness Applet 2.24.0 so I changed the package from acpi to gpm, as the regular Fn keys method does work.

Thank you both for taking the time to report and confirm this bug. Could you please attach the resulting log file of: gnome-power-bugreport.sh &> gpm.log to the report? You might also want to take a look to the Debugging instructions located at https://wiki.ubuntu.com/DebuggingGNOMEPowerManager for submit any other logs related to your problem - probably focus on the sections "Getting GConf values" and "Getting info from GPM". Thanks in advance.

Those are my results of `gnome-power-bugreport.sh`, `gconftool --recursive-list /apps/gnome-power-manager` and `gnome-power-manager --verbose --no-daemon' (the last one was working over 5 minutes, so i terminate it with ctrl+c). I don't know how submit few files in one post so I will do it one by one...

I have attached my log files as well. Also, I noticed that if you add the panel applet first, then close GPM and relaunch it, the applet will display the display "LCD: brightness 100%" correctly, until you scroll up and down on the icon. It then changes back to "Cannot get laptop panel brightness".
