sl400 Brightness "flickering" issue

[lostinthecold]

Hi,

I am not sure if other have this problem. Basically, if I open programs like: VLC, Virtualbox, some games (wesnoth and others). The screen will turn dark. Not completelly dark, but it will not be 100% bright like I prefer. 

As a matter of fact, after booting up on my Gnome (using ubuntu 8.10 here) the brightness is not 100% either, let's say 70%, and that's about the same level of brightness well I open one of such programs. 

Any ideas in how to fix this issue? 

Please let me know if you encountered similar problem.

Thanks. I was aware of this problem with the brightness keys being "fliped". I didn't know it was also related with the flickering.

Thanks for the info, I will try this module. 

Just for future reference, I have installed openSUSE 11 and, by default, the brightness keys don't even work! (the wireless card is recognized by default, however).
