Compiz is one of Linux's window managers, it's preinstalled on Ubuntu (you use that, right?) but I don't remember how to activate it or change properties since I use KWin, the window manager of KDE P.S. Anyone knows how to enable Compiz on KDE?
Compiz option make screen transparent when I get mu mouse over it. I'm looking way to make better pix arts in tpt, so I need some program that make tpt opacity, but I can draw to it.
