Public bug reported: I have a Lenovo ThinkPad x250. I've used 'xinput disable 9' to disable the touchscreen prior to Ubuntu 17.10. Now that I have upgraded to 17.10, if I disable the touchscreen with the prior command and then touch the screen with my finger, my user session is logged out and all open windows are lost. My finger touching the screen shouldn't cause anything to happen.
