Refresh rate revert on 60 Hz on reboot

view story

http://askubuntu.com – I just installed Ubuntu 12.04 (upgrade from 11.10) and when I change monitor refresh rate everything is ok, until reboot, on reboot my refresh rate revert to 60 Hz. I found similar threads on Ask Ubuntu but answers are not good for me. Is there any way for making a script which change refresh rate using Nvidia settings, or can you help me to fix this using xrandr. Refresh rate should be 85 and resolution 1280x960. Plz help. (HowTos)
