Description of problem: Since the update to the version below the nv driver seems to honour the Gamma value reported by my monitor (Eizo S1910). The display has a fixed gamma of 2.2. Earlier versions of the driver, however, used to ignore that and Xorg used a gamma of 1.0, for which the monitor is set. Thus, the picture looks quite awful with the new gamma. Setting "Gamma 1.0" in the Monitor section of /etc/X11/xorg.conf does not help, either. Version-Release number of selected component (if applicable): xorg-x11-drv-nv-1.1.1-5 How reproducible: Always Steps to Reproduce: 1. Attach monitor which reports a gamma value via DDC 2. Look in Xorg log after startup for the gamma used 3. Actual results: Xorg uses the gamma value reported by the monitor, instead of 1.0 1.0 1.0 like earlier releases Expected results: At least make this optional somehow. Additional info:
I'm seeing the same thing. You can try starting X with "startx -- -gamma 1.0" (or modifying the respective line in the gdm config accordingly) as a workaround. That does the trick for me.
The 'xgamma' can be used to reset the gamma value. -Joseph
Actually a bug in xorg-x11-server, should be fixed in rawhide.
