Comment 401 for bug 550625

Version 0.3 of the psmouse-alps-dkms package is now available at:

  http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.3/psmouse-alps-dkms_0.3_all.deb

Changes since v2:

* Improved cleanup after trackstick initialization errors

* Driver should still load if trackstick initialization fails

* Multitouch support for v3 protocol touchpads

* Filter out occasional "zero pressure" reports from hardware. These were causing random release events to be sent to userspace, which could appear as apparent clicks when dragging on the touchpad.

Hemanti: The first two changes are targeted at your issues. Even though you don't have a trackstick, it appears that occasionally on your hardware something is gong wrong with the trackstick check. As long as that's all that's going wrong the new version shouldn't cause the complete failures you were seeing before, but there could be a deeper underlying problem. Please let me know how it works, and keep an eye out for "trackstick E7 report failed" messages in dmesg.

Note that multitouch support is for *v3 only.* v4 has some difficulties that need to be overcome, and I plan to focus on getting everything else solid before working on that.

I think the driver is currently very close to finished, so everyone please give this newest version a try and let me know how it works. Thanks!
