Confirmed here too with CRT monitor. Whether I set Gamma with xgamma in the terminal or use the nVidia control, once the gnome screensaver kicks in, it resets it to the default (1), even though xgamma still reflects the values I set. If I open the nvidia control again, or retype the xgamma, the correct gamma is set once again.
