Just follow this:
Dash home>displays>click detect displays (there you should find your projector "extra display")> select projector display; check "mirror display option"> click apply
Also in options you can check if you want to show display just on the projector or just on the laptop. Ubuntu sometimes can have a problems with projector, in that case go to ubuntu service center forum and ask for help.

Ubuntu 7.10 is a Linux Operating System/Distro. Once installed on a computer or flash drive that is in the computer you should be able to connect to it on power up. If not make sure it installed correctly or try reinstalling it.
Ubuntu is an operating system, so just tell the installer to use the entire disk. However, an operating system is useless without software, and Ubuntu includes many software packages on a clean install.
