Can't change screen brightness on Windows 8

Hello,

 

I own a Satelllite L855-11T (I'm from Germany) and installed Windows 8 Pro x64 (DreamSpark full version). Everything works fine except for one thing: I can't change the screen's brightness.

 

I installed the newest drivers and TVAP, System Driver, etc. Toshiba Function Key doesn't work, don't know why. And Intel won't let me install the display driver: my system wouldn't meet the requirements. I thought there's an integrated GPU in Ivy Bridge?

 

Well, when I press FN + F2/F3 the brightness indicator bar appears and changes its value, but nothing's happening on my screen. I just stays the same (seems to be applied after restart). I even deactivated adaptive brightness, but it didn't help. Any other function keys are working fine (out of the box by the way). 

 

I hope you can help me.

You may want to post in Toshiba Europe's forums.
