Bug Description

Binary package hint: gnome-power-manager

Running 9.10 on a Dell Studio 1555

The fn+Brightness keys bring up the brightness bar in the top-right, and while the bar changes, the brightness does not.

Using power management, I can set the brightness bar to whatever percent, but it does not actually change the screen's brightness.

I have the Dell 1555 also and have the same problem with brightness control. Can someone please help fix this?

Similar problem since upgrading to 9.10. Setting brightness in gnome-power-manager does not do anything, and using the fn keys to lower the brightness works strangely - pressing the fn brightness down button takes brightness down to 50% but then starts increasing it again to 100%, all under the same button.

I am using Dell Mini 9 with an Intel i945GME graphics chip. This problem occurs on both 2.6.31 stock kernel and the updated 2.6.32 kernel i am currently using.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of Gnome Power Manager is available on Maverick and we are wondering if this bug is still an issue for you with that version? Could you please test and comment back? Thanks in advance.
