After struggling with this for a long time I found out that there is a "new" driver for input devices: libinput, that replaces synaptics. I followed the install instructions as given here: http://askubuntu.com/questions/649103/proper-touchpad-thumb-palm- detection-with-libinput
In addition I had to uninstall an older libinput package that had been installed as a dependency to vlc I think. Now I got thumb support and multi-touch support out of the box, and the pointer doesn't jump around on the screen any more when I'm typing. Hopefully others will find this helpful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1026046 Title: Missing support for thumb resting on bottom of clickpad To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-input-synaptics/+bug/1026046/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
