Backlight resets to full intensity after few minutes

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in gnome-power-manager.

Same happens to me with a fresh install of gutsy on a Dell inspiron 9400 / E1705. When running on AC power if I change my monitor brightness to some value near 50%, after a minute it automatically turns to 100% without "Dim display when idle" checked.

The Same thing happens to me. I am running a HP Pavilion dv9207us. When I am running AC Power my monitor gets really bright when left idle. It seems to be doing the opposite of what the dim feature does. The "Dim display when idle" is not checked or AC power..

Attached is a picture of what my power settings look like

I have a fresh install of gutsy and this problem just started occuring today. I have had gutsy since the 19th of October and I have not noticed this since today. I am fully uptodate also

 I have also attached my system information.

If there's anyway i can assist in fixing this bug. let me know. Please. thanks

I have made a video of what I think the problem might be or what it might be related to.

I have noticed that when the keyboard brightness keys are used to adjust the monitor's brightness gnome-power-manager settings doesnt seem to be aware of them.

Check out the video I have attached
