changing display brightness with proprietory Nvidia drivers in Linux Mint Debian Edition 13

Recent move to Linux Mint Debian Edition 13 got myself working on adjusting the screen brightness. The normal commands didn't work under my Sony VPCCW25FA so had to look at nvidia-settings to change brightness and contrast.

A single command will change the settings.

$ nvidia-settings --assign RedBrightness=-0.20 --assign GreenBrightness=-0.20 --assign BlueBrightness=-0.20

To load these settings after each reboot the config file (.nvidia-settings-rc) residing in home directory should be added with these settings. Find lines that specify brightness settings. Add a startup program with this line.

$  nvidia-settings --config=~/.nvidia-settings-rc --load-config-only
