Cannot change screen brightness with 10.4
I have just installed Ubuntu 10.4 on my laptop (Toshiba Qosmio G40) It recomended I install the new Nvidia driver version 195.36.15 after rebooting the picture was much better but know I can't change the screen brightness. Under the default screen driver on the live CD it was working.
My graphics card is NVidia GeForce 8600M GT using Nvidia.
The hot keys work as it shows the image in the top right that looks like it is altering the back-light but nothing actually changes.
Is there an easy fix for this? It doesn't sound like a big deal but is very annoying.
