X Windows - XDMCP
X Windows is used by almost every Unix and Linux machine with a graphical desktop. You can
connect to
any
Linux PC or server using XDMCP – the X Display Manager Control Protocol.
However, most Linux distributions ship with this feature switched off for the sake of security. To
enable it refer to your distribution's documentation.
Hint: The file /etc/X11/xdm/Xaccess should be
configured to allow XDMCP connections, and your Login manager must also be configured to
allow remote connections; see gdmsetup for the GNOME display manager, /etc/X11/xdm/xdm-
config for the X Display Manager and kdmctl for the KDE display manager.
To set up an X Windows connection, follow the usual procedure, choosing “X Windows
(XDMCP)” in the drop down menu of the “Choose connection type” window.
As with all the other connections, the “Connection name” identifies the connection and the server is
the computer to connect to, either by TCP/IP network name or IP address.
Check “Repeat Login” if you want the Login window for your Linux/Unix server to reappear after a
user logs out.
“Run on new vt” is checked by default and means that the X connection will run on a new virtual
terminal in genuine fullscreen mode. If this is unchecked, then the X connection will run in a
managed window. If you then check “Fullscreen”, the managed window will occupy all of the
display area. Note that running in a managed window is slower than running your X connection on
a new vt.
XDMCP Broadcast
If you want to connect to any willing XDMCP broadcast server on your network, enter “broadcast”
in the “Server” field instead of a server network name or IP address.
