Comment 11 for bug 817496

I found a workaround. I installed the debian package for synaptics which does not have some of the patches added.
Now I can tap and drag to select text, three finger for middle mouse button.

This is probably not the right way to do it, but it seems that this touchpad is not compatible with the patches added in ubuntu right now. Maybe there is an option to disable the multitouch functions, but I could not find it.
