Is there any way to have libinput 1.8 or 1.7 on Ubuntu 16.04 without breaking everything? There are issues with touchpad tap sensitivty on the Dell XPS 13 and Xenial's version of libinput (1.6.3) does not allow adjusting sensitivity.
If it is possible, how would I go about upgrading this package? Adding a PPA? Compiling? If the former, which PPA and if the latter, how should I compile it?
