[ (k)ubuntu 6.10,  nvidia quadro nvs 120m ]

Hi, 

So I figured out how to nominally run my nvidia-equipped lapstation with dual 
heads (nee screens) as needed. 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,
