I suggest changing title in "Ubuntu 12.04 always resets refresh rate to 60 hz after reboot", I have nvidia latest 304.60 on lcd monitor that starts with proper resolution after adding lines in xorg.conf section monitor and section screen but cannot start with my preferred refresh rate of 75 hz always have to use nvidia-settings, I tried using xrandr to force 75 hz with the command xrandr -s 1440x900 -r 75 but it sais Rate 75.0 Hz not available for this size, so it seems as if X completely avoid taking into consideration refresh rate different than 60 hz, here my xorg.conf
