[Bug 207473] Re: Screen brightness double level changes

[Kuba Górski]

I have noticed something interesting..
When a menu is open (Applications,Places or Systems), and Fn+up/Fn+down keys are pressed, the screen brightness is changed correctly without any double/quadruple steps, although, now there are only 5 brightness levels, whereas my LCD screen supports 8 levels . Can somebody confirm this?

I can confirm that killing the gnome-power-manager process fixes the
multiple brightness level hopping, however there are only 5 brightness
levels.

Now, the amount of brightness "hops" in my case have varied from 2 to 4
steps for a single Fn+Up/Down press. Which leaves me with the conclusion
that the acpi & gnome-power-manager brightness controls are overlapping.

For now im sticking to a gnome-panel brightness applet, the "blacklist video" hack creates a lot of new problems here.
Running Dell M1330, GF9400M GS, 2.6.27-7-generic, and latest Intrepid updates as of now.
