I have an old 600X. How can I use it with my T42 to run a multi-monitor display? The T42 as the primary display, the 600X as the secondary, with the ability to span the screen display over both monitors if possible.

Q: Can I use the display from the 600X without booting it up?

Q: I am running Red Hat Linux on the T42, so would be looking to use xrandr or something like that. Any web links or hints welcomed.

Q1: No you will have to boot the 600X.
