Each of the guys at the office has a dual head box running Fedora Core 3 for displaying Big Brother and other monitoring tools. We use Matrox G550’s for video, since they seemed to provide the most consistent output on two analog monitors.

There is a minor problem with the driver that Fedora ships: it disables analog output on the DVI connector. The problem appears the first time the machine is restarted after everything is up and running. The issue is easily resolved by installing the mga drivers from the Matrox website.
