Comment 29 for bug 868400

I would like to add that this seems to be very much a finger detection issue. I'm having this problem on an Asus G73SW recently upgraded from Natty to Oneiric. I booted the Oneiric LiveCD to see if it was a config issue, and I still have problems, although they're a little different (the three-finger window drag doesn't seem to work from the LiveCD, the window handles don't appear from three-finger clicking either).

My cursor locks up with varying frequency, but everything else is still in full swing. I can click with the physical buttons, an external mouse works perfectly, and the keyboard is still responsive. However I experience an additional symptom that I don't see anyone else describing. After locking up briefly, sometimes it will move erratically on its own. It'll grab a window, jerk it all over the screen, and sometimes leave it positioned halfway off-screen or maximize it (by dragging to top, I believe). I get the impression it thinks there are fingers all over the touchpad, almost like it thinks I'm palming it, but a little different. It seems to think there are several points of contact either stuck or moving erratically.

I have no problems with this touchpad in Windows 7, nor did I in Natty, so there's no question we have a bug in an update.
