I didnt see that you are using Unity. u-s-d also launches syndaemon with the "-t" option, which means motion won't be disabled, just clicking and scrolling. Perhaps the "Synaptics Off" patch would help, atleast on supported hardware.
I am not sure that Unity7 has been ported to use libinput, I suspect not and clearly that would not be an option for LTS. ** Changed in: gnome-settings-daemon (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576685 Title: Disable touchpad while typing is not active nor can it be enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-gnome/+bug/1576685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
