This is not supported. Never was, probably will be in some future versions. No, certainly not 10.2.
Most recently, I used SaX to try to enable "DualHead" mode. That has been partially successful. What I expected was two displays "side by side" with the mouse running between them. What I got is both displays running (at different resolutions) but showing identical output. Sounds good, right? Well only to a point.
Depends on how you configure it. With intel drivers only clone mode was possible, that will change with 10.2.
The problem with this arrangement is that if I boot with the external display connected, all works great, but despite the amount of time I work in this mode, I still use the system more without an external display connected. If I boot without an external display, the LCD never powers up! So I can't see anything, and I can't even try to logout or shutdown the system... I have to force it off with the power switch (thank heavens for journaling file systems!)
Never boot a machine with the external monitor attached. This only works
on with some drivers on some machines in some versions...
If the LCD doesn't come up *without* an external monitor connected, that
is a *very* obscure bug, and worth reporting.
