Lenovo Ideapad 2 13 (2 in 1 convertible, touchscreen)
Ubuntu 18.04 (+ 17.10, + 16.04)

even after installing 18.04 and the latest updates on Jan 2nd 2018 the following feature persists:
a few times a week the cursor goes nuts - it looks like it's jumping to the lower left corner (gnome desktop), clicking, and thereby calling the program tiles onto the screen. Then clicking again making the tiles disappear, clicking again calling the tiles,..... sometimes with quite a high frequency. This turns the laptop pretty much useless because it's "trapped" in this state. Whatever you try it's always calling the tiles :-(
This happens even if I'm not touching the notebook at all!!
I couldn't find anything to influence this behavior. Even after rebooting it continues! But at some random point in time the jumping stops and the notebook can be used as before and works like a charm - until the jumping starts again.

Because I used the fix from https://askubuntu.com/users/750621/keringar (Thank you!!) the on screen keyboard is not coming any more. But for me it looks that the root cause of the osk popping up is the cursor jump/click.
As I have tried very many of the suggestions above and in other forums I tend to believe that it's really a bug somewhere deep inside (graphic driver?) as this bug appeared with Gnome and also Unity desktop.

Solving this for good would REALLY promote the use of Ubuntu :-)
