Explanation:
From http://www.xfree86.org/current/X.7.html#sect4:
On POSIX systems, the default display name is stored in your DISPLAY environment variable. This variable is set automatically by the xterm terminal emulator. However, when you log into another machine on a network, you will need to set DISPLAY by hand to point to your display.
