Re: [XFree86] How to adjust gamma with SiS 740?

Thanks for your answer!

Actually I don't know whether I have that 7019 chip since I may not open that 
laptop housing thanks to warranty reasons, but I think it is since I can plug 
a TV on that thing.

What can I do to get work in progress to get gamma correction supported? It 
works on Redmond 2000, so it should be possible in Linux also. If I can do 
anything to help I will do. :-)

Have Fun
Markus
