I have a similar issue.  My laptop is an Asus N50V with a GeForce 9650M
GT video card; the external monitor is a Viewsonic VX1940w (1650x1080).
I'm experiencing the issue with the 195.36.15 nVidia drivers using
Ubuntu 10.04 (i386).

If the display is set to "Separate X screen," my mouse cursor starts on
the main (laptop) monitor and works fine there.  As soon as I move it to
the external monitor, it gets stuck within that monitor.  Moving back
toward the other one results in the cursor stopping just like if the
external monitor were the only one connected.

I also use Synergy and moving the cursor from the desktop (server) to my
laptop/ext. monitor setup only allows the cursor to use whichever
monitor the cursor was already on.  So, if the cursor was still on my
laptop screen and I use the mouse from the main computer to move the
cursor over to the laptop to control it, the cursor can move all around
the laptop screen, but moving it to the external monitor doesn't work
(but I can move it back to the desktop just fine).  Similarly, if I have
moved the mouse cursor to the external monitor, that is the only monitor
I can interact with via the mouse.

A temporary work around is to switch the settings to TwinView, which
makes the cursor work but has other limitations.
