external monitor entertainment - questions!

[=JeffH]

Hi,

So I figured out how to nominally run my nvidia-equipped lapstation with dual
heads (nee screens) as needed, using the "nvidia" driver (I'm using rev 9755). My xorg.conf file is attached below.

Note that what I've been able to do is *not* "hotplugging". To go from using
just the builtin LCD screen to both the builtin LCD screen and an VGA-attached
external screen simultaneously, I stop X (eg via Crtl-Alt-Backspace) and then
restart it, and the external monitor turns on, as screen 0 interestingly
enough. And the builtin LCD screen is also on, and sports a desktop, although
I can't drag the mouse pointer over to it.

So I was using the external screen desktop, and was stretching a window off
the right edge of the screen, and somehow my mouse pointer was suddenly on the
builtin LCD's desktop (apparently screen 1). I was not able to figure out how
that happened, nor re-create it, nor figure out how to get the mouse pointer
back over to the external screen desktop.

Anyone have any thoughts on how this might have happened? How i might be able
to get the mouse pointer to go between desktops at-will?

Any obvious brokenness in the xorg.conf file? it's a hack and some of the
stuff in there I just pulled off this list and ubuntu forums to try.

thanks,
