Brightness and Contrast controls on iMacs

[Scott McMahan]

I'm looking for a way to adjust the screen settings on my iMac.  I've 
search the list/newsgroups and the answers I've found don't work on CRTs 
(fblevel) or don't really address the right problem (xgamma).  Is there 
a utility available to handle this problem?  If not, is anyone working 
on one?  If not, can anyone help point me in the right direction so I 
can start working on one?
