When it was VGA port, the setting of Gamma in xorg.conf works just fine:
Section "Monitor"
Identifier "Monitor1"
Option "DPMS"
Gamma 0.75 0.75 0.75
EndSection
I can see it in /var/log/Xorg.0.log.
However after changing to DVI cable it the Gamma setting does not work. Same card (Geforce GE3700GS), same monitor, same driver (nouveau), only the cable is changed from VGA to DVI.
Is that a bug, or it is just that with DVI we cannot change Gamma?

You can use xgamma.

Thanks
~% xgamma
-> Red 0.750, Green 0.750, Blue 0.750
~% grep gamma /var/log/Xorg.0.log
[ 15.603] (II) NOUVEAU(0): Using default gamma of (1.0, 1.0, 1.0) unless otherwise stated.
So, apparently, the 'Gamma 0.75 0.75 0.75' directive in xorg.conf works. It's just that it does not show in /var/log/Xorg.0.log
Thanks for fast and helpful advice.
