For what it's worth, I too was having this same bug bite me multiple
times per day on my primary workstation. My setup is fairly common
(dual head NVidia), but I found two things that caused the frequency
of the bug to occur:
 * Using VMWare workstation in full-screen (single monitor)
 * Using "Synergy" (http://synergy-foss.org/)
If I kept my VMWare screens less than full-screen, and didn't use
Synergy at all, I found my rate of "stuck mouse" problems went down to
about 2/day (down from 8+/day - almost hourly).

The fix that was mentioned in post #36:
    https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/570151/comments/36
...was ultimately the resolution for me.

This patch was added to the Maverick (10.10) release of Ubuntu, so I'd
suggest you try upgrading your system since you stated you're on
Oneric (9.10).

If you're not comfortable with that upgrade, you might be able to
upgrade just the X11 components and see if that resolves your issue.
But that upgrade might introduce different bugs and then you're in a
bad spot.

As always, backup your system before doing either upgrade route.
