[Other Info]
It is worth noting that the Dell XPS13 L322X is from the Sputnik series
of "Developer Edition" laptops from Dell, which are supposed to have
excellent Ubuntu support and came pre-installed with Ubuntu 12.04 when
first released. Every release from 12.04 to 17.10 had perfect out-of-
the-box touchpad support, so this bug is a regression. I realise this is
because of the change away from synaptics as the input driver, but in
terms of user experience presents a serious regression.
