XOrg, Two Video Cards, Two Monitors, Mirroring?

[Dave_Lindquist]

I've been searching and haven't found a clear indication of how to do "mirrored displays" in XOrg (or if it is even possible).

Basically, I have:

- Two video cards (possibly different makes)
- Two monitors (definitely different capabilities, but same screen resolution possible).
- One X Session.

What I want to do is be able to tell X to display exactly the same content on both displays -- a mirrored display.

I can add two adapters and two monitors into the XOrg config file, but how do I tell it to mirror the displays? Do I need xinerama for this?

Any help appreciated!
