<WRAP round box muchbigger centeralign>Video Wall Construction</WRAP>

======Objective======
This project will have you putting together a tiled display wall and logically joining all the screens together.
======Prerequisites======
To do this project, you will need to have successfully completed:

  * [[spring2011/hpc0/projects/desktop_install|Linux/*BSD Desktop Install]]

======Ingredients======
You will need:

  * at least 2 computers (with a basic Linux install, Debian tends to stay out of your way more than Ubuntu)
  * each computer equipped with a dual-head video card
  * four LCDs (two driven by each computer)
    * arranged the LCds into a 2x2 matrix

======Background======
The concept of a Video Wall (better called "Tiled Display Wall") is the perfect visual example of High-Performance Computing. Taking multiple independent units, each with a given ability, and allowing them to work together to create a new unit that is more capable than the sum of its parts can be an impressive feat.

But, unlike doing so on a cluster, a tiled display wall can demonstrate these concepts to those not as familiar with such concepts.

======Process======
The process of performing this project will include roughly the following:

  * get X up and running on both machines
    * get dual head operation up for both heads
  * obtain Xdmx (you may have to grab this file from a Debian Etch system, even if you're running a more modern release)
  * configure Xdmx (be mindful of screen offsets with respect to monitor panes)
  * run it, along with other bits (Window Manager, if desired)
  * demonstrate the connected nature of the monitors
