I also have this problem. I run three monitors using two nVidia 9800GT cards. The problem is definitely related to the way the monitors are arranged, and what is plugged into what card. My monitors are arranged such that card #1 is connected to one main monitor in the middle and card #2 is connected to two monitors on the left and right of that one. I can move my mouse from the main monitor (X screen 0) to the monitor on the right (X screen 1), but I can not move from the main monitor to the monitor on the left (X screen 2) without giving the mouse a violent seizure, which sometimes crashes X, and sometimes just sits their being really annoying.

This all worked fine with ubuntu 9.10, but after upgrade I end up with this. Really a downer.

My very meager knowledge and powers of deduction / observation have so far failed to even point to a particular bit of software as the cause of this problem. I have not heard of anyone who uses ATI cards having this problem, so it could be that new nVidia drivers are at fault. It is also possible that we just don't have any complaints from ATI users yet, and X is at fault.

Really hope this gets resolved soon, as I am not happy about the idea of going back to 9.10 or pulling any of my monitors.

Will report back if I find out anything useful. --Daniel
