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 Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1026046 Title: Missing support for thumb resting on bottom of clickpad Status in Xserver Xorg Input Synaptics: Unknown Status in xserver-xorg-input-synaptics package in Ubuntu: In Progress Status in xserver-xorg-input-synaptics source package in Precise: Confirmed Status in xserver-xorg-input-synaptics package in Debian: New Bug description: When using the trackpad on the MacBook Pro In Mac OS X it is possible to have the thumb resting (ready to click) on the bottom part of the touchpad while moving the mouse pointer around with your index or middle finger. Likewise it is also possible to use two finger scrolling with the index and middle finger on the upper part on the track pad while resting the thumb on the lower part of the trackpad. This behaviour is not currently supported with the synaptics driver in 12.04. It wil register a two finger scroll when the thumb is resting in the bottom part and index finger moves around in the upper part. I have tried playing aroud with the setting AreaBottomEdge that disables all motion on the bottom part of the touchpad. Unfortunately when this setting is enabled it still detects a finger in the area, so it wil register a two finger scroll like before.
