Public bug reported: I enabled two-finger scroll for my touchpad in Settings. Initially, it worked fine. However, after closing the laptop lid and suspending the computer, three fingers are needed to scroll. Two fingers just moves the pointer, as with one finger. Toggling the setting does not help, nor does logging out and logging back in. Restarting does fix it - until the computer suspends again.
This is a ThinkPad T440s running Ubuntu 17.10 after upgrading from 17.04. I'm using Wayland with libinput 1.8.2-1ubuntu2. libinput is my best guess for where the bug lies, but really I have no idea.
