I installed fglrx-updates package and this issue started occuring:

When I move the mouse cursor to the right edge of the screen, it "wraps" over and appears on the left side of the screen. If I have my second monitor (which is on the left of my main monitor) enabled, it moves from the right side of the right screen to the left side of the left screen.

I purge removed fglrx-updates and went back to fglrx and the issue has persisted.

I have two Radeon HD 6950's in Crossfire.

How do I stop this from occuring? It's becoming quite frustrating.
