I'm hitting this on Ubuntu 14.10 as well. Out of the box, the left button generates button 4 events, the right button generates button 5 events, and the middle button generates nothing at all.
The situation improves a little bit by setting UpDownScrolling=0 ("synclient UpDownScrolling=0"), after which the left button generates a double left click and the right button generates a button 2 event. However, both buttons generates the press _and_release events right away - and no event is generated when the physical button is released. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1414930 Title: Buttons of Synaptics trackpad doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1414930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
