Usually, when installing programs from source, you open a terminal window.
Change to the folder that it is contained in (be sure that you did any necessary decompressing), run the configure script (type ./configure), type make, and as root (or through sudo) make install. Although sometimes the program comes with some sort of install script that does the job for you.
If you don't know how to use the bash shell, learn how to FAST.
PS. Search Synaptic for the driver first, it will make installing and updating it faster and easier, unless your Linux can't connect to the web because of driver problems.
If any errors pop up,then you are probably missing something that is needed by the program
update: if you can't find anything in synaptic, hire a pro to install it for you, that package will not work with any of the usual instructions
