A launcher for starting games in a second X session
XGamer is a launcher for starting games or applications in a second X11 session. It can be launched from the command line or has a Gtk2 GUI for managing and launching games. It has integration with openbox (a light-weight window manager) to provide a suitable environment for running processor or graphics intensive applications.
By running in a second session games can run at the same time as compositing programs such as Compiz in your main session. It It also isolates your primary X11 session from unstable games and applications preventing bugs or crashes propagating to other applications. Running a second session can also take advantage of multi-core processors.
