It doesn't sound like you've actually installed TuxOnIce - that would require adding the PPA. It sounds to me like you've just installed the TuxOnIce userspace part (the nice user interface), and via broken dependencies (uswsusp is unrelated to TuxOnIce) uswsusp has come along for the ride.

I would try to uninstall both the userui package and uswsusp.
