Hey everyone,

I'm having trouble changing the brightness of my screen ever since I installed the driver for my NVIDIA card.

Basically when I use the brightness control settings on my keyboard, the little scale notifier in the upper-right-hand corner changes, but the actual screen brightness does not. Even more curiously, whenever I reboot, Ubuntu runs at the brightness that was set previous to booting, but I can't change the brightness level beyond that.

It works fine on Windows, so I don't think it's a hardware issue (I'm using 10.04).

I tried the fix described here:

but all it did was mess with the driver and screw up the graphics. I changed the grub file back and used backed up graphics settings and managed to get my graphics back under control, but no luck with the brightness setting.

Sorry to bother you guys and thanks in advance for any advice you might have.
