Comment 1 for bug 387608

I have the same issue on an EEE 901.

Even if I disable the dimming and reduce backlight brightness options in power manager, the behavior is wrong.
I can change the screen brightness to the level I want, but after an idle time that corresponds to when the power manager would have blackened the screen, the brightness goes up to full again (even when these options are disabled) instead of blackening.

The power manager should dim and reduce backlight on the screen if these options are selected, but it should remember the brightness level I have manually selected when it goes back to normal. Even if my manual brightness is lower than the dim level.
