Bug Description
Binary package hint: gnome-power-manager
The slider brightness Applet has value (%) inverted after the last update. When moves slider to up (plus) the screen brightness goes down. When moves slider to down (minus) the screen brightness goes up. I'm using version is 2.24.0-0ubuntu 8.1.
SRU Justification
Justification: ACPI brightness handling inverted or not functioning for several systems. acpi fixes committed to the proposed kernels expanded use of ACPI calls to handle brightness. This however exposes a number of systems which have broken ACPI brightness handling
Impact: a number of laptops reported either inverted brightness handling or totally non-functional brightness control
Fix Description: the fix adds an ACPI brightness validator which suppresses use of ACPI calls which are deemed broken.
Risks: as we are supressing ACPI brightness support we may suppress it where it is required
TEST CASE: see bug report

I have the same problem after the update of the kernel from (2.6.27-10-generic to 2.6.27-11-generic).
I think it is a kernel problem since the is a lot of change is th release note concerning the brightness.
Which laptop do you have?
I have an asus laptop (may come from asus-acpi).
