Cannot Connect to an X Server

Arm Forge does not open and you cannot connect to Arm forge running on a remote server. You see the message "Map can not connect to X server".

The DISPLAY Variable is Not Set Correctly

The DISPLAY variable ensures that Arm Forge can connect to the X server.


  1. Check that the DISPLAY variable is set to 'export DISPLAY= : 0'.
  2. Ensure that you can run simple X applications, such as 'xterm' from the same command line.

If you continue to experience problems, contact Arm support.
