I was able to fix it with the comment by nschmelzle here: https://gist.github.com/tsrivishnu/5b467f07374ce42ad6d97b6a3fdf0ea5
The problem was that the touchpad was using the synaptics driver, while the trackpoint used libinput. The solution was to uninstall the synaptics driver: apt remove xserver-xorg-input-synaptics Now middle click scrolling with the trackpoint works again in Ubuntu 18.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246683 Title: Middle button does not work for scrolling in Ubuntu 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1246683/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
