Can't get xinerama to work

[Colin Paul Adams]

I've edited my xorg.conf to look like the text below, in order to get
xinerama to work. But when I do so, I get errors in .xsession-errors:

Xlib:  extension "RANDR" missing on display ":0.0".
Xlib:  extension "RANDR" missing on display ":0.0".

Am I supposed to be able to get this to work?
