Can you pls provide URL for the patterns which are the best, according to your 
taste?
And what do you mean under "screenshots look better"?
I think it's very subjective - wether screenshot looks better or not.
Any way *to measure* and return back some alpha-numeric value, indicating 
wether gamma is o.k. or not?

|  Something like:
|
|   xgamma -gamma 1.2

I tried it with my system, I see changes on screen.
So I guess my ATI Rage Mobility+LCD is supported.
Not sure, though, what should be final result.

man:xgamma is not very informative.
It lists options, but even doesn't tell you what is the valid range for the 
gamma!...
And no explanation, how someone should change his gamma.
