tompotts- looking at your output, it looks like wheel emulation is still set to false:
Evdev Wheel Emulation (286): 0 I don't know what your trying to get it to do, but for me, my trackball works the way I want it to when I turn on the wheel emulation (set it to 1). Based on the output you posted, you could try: xinput --set-prop 11 286 1 which would turn on the wheel emulation -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581088 Title: Middle mouse (wheel-click) button stopped working after upgrade to 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1581088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
