Public bug reported:
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.
