If $DISPLAY is set or not usually depends on the terminal
emulator where the shell runs. For example, classic xterm
sets $DISPLAY to the correct display name. For remote
connections, you might need to set $DISPLAY manually (for
example with hostname / IP and display number, maybe with
a screen number or "sub-display" if needed).

See "man X" for details, section "DISPLAY NAMES", and also
the following section "ACCESS CONTROL". Yes, this stuff is
actually documented. ;-)
