Public bug reported:
The issue is that the settings synclient uses for the touchpad are
wrong. If you compare the settings used in Ubuntu versus the ones used
in Kubuntu, you'll notice 3 key options which make the touchpad
unusable. The settings are: MaxTapMove, VertScrollDelta and
HorizScrolDelta. What lead me to believe kde is the culprit is even
though I added an Xorg config file and verified it loaded the settings,
synclient showed the old broken settings. If you open up the kcm-
touchpad config and look for the UI widgets that allow you to modify
these settings, their value ranges disallow setting them to the correct
values (535 for MaxTapMove and -243 for both Vert and HorizScrollDelta).
The only way to workaround this is to use synclient itself to set these
values. Once that is done, the touchpad will perform as well as it does
under Ubuntu.
