Hello sasha@aftercode.net. It was Sunday when you wrote:

This is what they do. The NVIDIA drivers set each of your screens up to
whatever resolution you want, then tell X you've got one huge screen as
big as the two.

Damn, thought as much.

| Try configuring your drivers to not do that, and use Xinerama instead.

Can't... that's how the drivers work. NVIDIA are 'considering' adding
the emulation of some Xinerama stuff to their driver, so I suppose I
could go and annoy them :-)
