The latest KDE patches to date completely break my multi-monitor setup:

Anything more than just one monitor and KDE freezes hard on login/logout

Multi-monitor setup works under Gnome

KDE freezes under kernel 4.10.* and 4.9.* so I assume is not related to the latest 4.10 problems.

Is it possible to roll back the full KDE to a previous version? Or roll back Fedora to a previous patch date?

Thank you.
