Public bug reported:
On Lenovo 300e (Winbook w. touch), after suspend (after reopening the
screen) a problem occurs with the touchpad. With original and latest
bios, on Ubuntu 18.04 and 18.10. Mouse control via the pen on the
touchscreen works right away but the touchpad initially fails to
activate after suspend. The problem is logged in the syslog:
