Bug Description
Occurs on HP Pavilion DV6 laptop
Ubuntu 10.04
Symptoms: Laptop touchpad lost button functionality after kernel update.
Tapping still works as left button press, but left, middle and right button standard functionality no longer working. Note that the touchpad has the buttons as part of the pad.
From the excerpts of the working and non-working dmesg, it looks like "clickpad mode" is no longer enabled. Perhaps this will help in fixing this bug in Ubuntu.
Last working kernel package: 2.6.32-32-generic
Non-working kernel packages: 2.6.32-33-generic

Just had kernel package 2.6.32-34-generic update, and...the problem still exists.
Hopefully the Ubuntu devs have some time to look at this!
