Yeah, "don't do that". The RandR 1.2 code in the server exposes the
Xinerama extension; the DIX-based Xinerama code crashes stuff. Yes, that
should be fixed.

Yeah, i830 laptops use an external chip to drive the LVDS and we haven't
managed support for any of them other than the one in the X30 laptop
(IVCH). That support was added after 2.0 was released; you should try
the current driver and see if it works now; if not, you probably have
some other DVO LVDS controller chip.

That's almost certainly a WM problem; please verify this by using
something else.

Newer driver bits may help.
