Short version:
$ sudo dnf copr enable ajax/upstream
$ sudo dnf upgrade
Long version:
I've set up a copr containing a rebuild of the X server and drivers for
the upstream 1.20 release candidates. Unfortunately the upstream and
Fedora schedules didn't line up as well as I'd have liked, so I'm not
going to try to land this for F28 GA. But I would _very_ much like to
push this as an update, and would appreciate any and all testing and
feedback.
