Public bug reported:

Binary package hint: xorg

The mouse is unusable on a second monitor using the nvidia drivers and
Xinerama (Installed: 2:1.1-2).  Upon moving to the second screen, the
mouse cursor movement is erratic (although it does respond vaguely to
physical mouse movement).

The problem was introduced with lucid (and continues in beta 2).  The
mouse works as expected on the second screen in both intrepid and karmic
with exact same xorg.conf and nvidia drivers.

The problem appears even with only the minimal settings in xorg.conf to
enable dual monitors.  The problem appears whether the second monitor is
rotated or not rotated.  The problem does not occur with nvidia's
TwinView implementation.

The mouse and all other aspects of X work fine in lucid *without*
Xinerama enabled.  Enabling Xinerama causes no problems except this one.
The bug is not present in Debian unstable.

The new bug of course forces one to use separate X servers when wishing
to rotate only one monitor in a set -- a limitation that was not present
in prior releases of Ubuntu or other distributions.
