[xinerama,nvidia] howto to increase brightness on the right screen only ?

Please find my xorg.conf. Everything is possible with Linux, so, sure it is. Someone has already made this? thank you for the hint

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

Just run nvidia-settings (which is installed with the nvidia driver) and select "X Server Color Correction" for the screen you want. You can adjust Brightness, Contrast and Gamma there.
