I have a Dell Latitude E6500.
I'd seen this problem with my 3-button IBM USB mouse, but it went away when I
upgraded from Ubuntu 10.04 to 12.04.
I have another external IBM USB mouse, this one with a wheel, and am still
seeing the problem.
So far I can temporarily stop the problem by un-plugging re-plugging the
mouse; I can also temporarily stop the problem with the command
xinput set-prop 13 Device Enabled 0
One thing to note is that the temporary fix works even if the device number
DOES NOT match the AlpsPS/2 ALPS DualPoint TouchPad. I don't believe the issue
is a conflict between the two devices for this reason.
I think that the mouse-driver is getting into some crudded-up state that gets
reset when I unplug/replug the device or if I run the above xinput command.
My best guess is that Ubuntu has real drivers for some mice and uses a buggy
default-driver for anything else, and 12.04 included a driver for my first
mouse but not my second mouse. Can anyone at Ubuntu confirm this? Or give us a
better explanation?
