Comment 4 for bug 96843

Terribly sorry to hear that your laptop died. Unfortunately if there is no failing exhibit it is nearly impossible to work on your original problem so I will mark this as Invalid. I also tried finding other duplicate/related bug reports and there do not seem to be good candidates.

The behaviour however most likely was due the loaded synaptics driver in case you had any ps/2 (emulating) mouse device present. Any sort of touchpad or tablet is most often the most likely candidate for such behaviour, or the other mice being detected as such (synaptics looks for ps/2 mice generally).
