Try using the baobab tool to find the big files on your disk, the delete them. Make sure you backup anything important.

You can install it as part of the gnome-utils package, either through your package manager, or by using a terminal and the command "sudo aptitude install gnome-utils"

You can also gain a little bit of space by cleaning your package cache, either through the package manager or by "sudo aptitude clean"
