wine users - Jun 2004 - Wine gamma change issue

Hello List,

I'm hoping someone else might have a solution for a particularly strange
problem that I have been having. I am running wine 20040615, on a slackware 9.1
install running dropline gnome and the 2.6.6 kernel. Whenever I run a game that
requires OpenGL, I often have to adjust the brightness of my monitor so that I
can see what is on screen. It is an old monitor, and has seen better days. This
was always just a mild inconvenience, as I would write the gamma change into a
script to launch the app anyway. Recent versions of wine seem to be ignoring the
current gamma (xgamma -gamma 4.6) and are running extrememly dark. Deus Ex is a
good example. I can manually adjust the brightness to 4.6, start the
application, and right before the full screen mode starts the gamma switches
back to 1.0 and I can hardly see anything on the screen. No error messages
pertaining to gamma settings are present. My assumption is that because the game
has an internal brightness adjustor that somehow wine is feeding the game a
gamma setting of 1.0, and then the game is using that as a base and adjusting up
or down from 1.0, as opposed to adjusting up or down from 4.6, which it should
be. Does this make any sense? Is there a setting or a line of code that I can
tweak to get Wine to recognize the current gamma setting? Any ideas?

would using a different X server be an option?
If so, you can ask X to use an individual XF86Config, and you can add the  
desired "Gamma" parameter to the "Monitor" section in that
new
"XF86Config_gamma" file

here's a bite of my XF86Config file to deal with an LCD monitor

Section "Monitor"
         Identifier   "Monitor0"
         VendorName   "Monitor Vendor"
         ModelName    "Sony GDM-17SE2T"
         DisplaySize  337        270
         HorizSync    30.0 - 85.0
         VertRefresh  48.0 - 150.0
         Gamma        0.6
         Option      "dpms"
EndSection


This guy here sort of puts it all in a script:
