The export command sets the DISPLAY variable to your local machine, this variable is how X apps figure out what X server to connect to. The xhost command allows programs running on your local machine to connect to your desktop. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
