dual screens - twinview - working config went wrong!

Hey guys,

Just upgraded to feisty. Now when I start gdm, I have the dual screens
active, but my mouse can only travel around 10 pixels into the right
screen (before hitting an imaginary barrier). When I log into gnome, it
kicks off 2 gnome sessions (gnome bar etc.) one for each screen.

Tried xinerama and twinview (currently still in twinview mode with no luck.

X11 does not error at all, the log shows a perfect start, twinview
loaded and the correct resolution for the 2 screens combined.

My config was not changed during the upgrade, so I don't understand why
it would work for an earlier version and not here... possible bug?

Any help would be great.
