Public bug reported:
In Ubuntu 16.04 with gnome-shell, the gnome-shell would crash every time
I touch the touchscreen of my laptop (ASUS-S400CA). Sometimes the
session would just restart, but when I touch again the whole session
would just crash and drive me back to gdm.
There are related log line in journald says:
