I reboot once a day reacting to a complaint about compiz crashing. It may not matter but terminal command option -v (version according tho the man page) does this:
Deimos ~> compiz -v compiz (core) - Warn: Unknown option '-v' compiz (core) - Info: Loading plugin: core compiz (core) - Info: Starting plugin: core compiz (core) - Error: Screen 0 on display ":0" already has a window manager; try using the --replace option to replace the current window manager. compiz (core) - Info: Stopping plugin: core compiz (core) - Info: Unloading plugin: core Trying the --replace option completely disables the terminal session so that it will not accept further commands.
