Thank you for the hint. I tried this: k2@kermit16:~$ xinput list-props 14|grep 321 Synaptics Tap Action (321): 0, 0, 0, 0, 0, 0, 0
k2@kermit16:~$ xinput set-prop 14 321 2 3 0 0 1 3 0 k2@kermit16:~$ xinput list-props 14|grep 321 Synaptics Tap Action (321): 2, 3, 0, 0, 1, 3, 0 That helped a lot. I can now using the touchpad for tapping and for dragging windows, but I must renew this after every login. I do not use Unity, but GNOME. So there is no unity-control-center. In my gnome-control-center mouse on 16.04 the touchpad controls are missing - see attachment. I see these controls under 14.04. ** Attachment added: "Bildschirmfoto vom 2016-04-24 14-43-37.png" https://bugs.launchpad.net/ubuntu/+bug/1573906/+attachment/4645299/+files/Bildschirmfoto%20vom%202016-04-24%2014-43-37.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573906 Title: Touchpad features not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1573906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
