Ubuntu Control Center (UCC) is an unofficial application inspired by
Mandriva Control Center, designed to bring simplicity and a less
cluttered interface (because a lot of applications add themselves to
the GNOME Control Center automatically) to manage the Ubuntu system
settings for the simple user.
Besides being an application you can use to launch various system
settings, UCC also lets you switch between low and high performance
graphics cards (if you have a netbook with 2 GPUs)
