Running DMX

 

Getting DMX started should be simple now. Start a session on boba142 (ssh boba142) and do the following:

Backup the DISPLAY environment variable to LOCALDISPLAY and then set it to:1.
csh example:

 setenv LOCALDISPLAY $DISPLAY
 setenv DISPLAY :1

Then type this command:

 Xdmx $DISPLAY -input $LOCALDISPLAY +xinerama -configfile /<path_to_file>/wall.cfg

Note: See this page for more information on the display variables.

You should notice all the monitors on the wall go black, and a cursor (barely visible) that you can move should appear.

You operate the mouse and keys via the DMX Console window (see below).

The +xinerama option makes the display wall act as a unifed desktop and the -input gives Xdmx the location of our input devices. To start applications on the display wall, all you need to do is open additional ssh connections to boba142, set DISPLAY to :1, and run the applications you desire. If you would like a desktop to work with, simply open gnome (gnome-session) or use tab window manager (twm).

Here is a screenshot of the DMX Console window that should appear.
