Public bug reported:
This is pretty much guaranteed to happen at some point after each
reboot. The touchpad will behave (it's not really used as I almost
always use an attached Logitech USB Wireless Mouse) as it should for a
while and then at some point the pointer starts going crazy, jumping
left and right over and over.
There doesn't seem to be any specific trigger, it just happens, and
there doesn't appear to be any specific time frame either. Sometimes it
happens within an hour of a reboot, sometimes it can take a day or more.
But once it happens and the pointer starts jumping left and right on
it's own, the only cure is to rmmod psmouse.
I can reload psmouse and be OK for a while, but invariably, the twitchy
pointer returns.
This is a regression in one of the recent kernels for Oneiric. I have
had Ubuntu on this system since Karmic and have never experienced this
issue until a couple months or so ago with an Oneiric update. In fact,
I do not recall experiencing this with the original Oneiric released
bits.
