I would like to discuss and propose that we as KDE SIG move forward and
attempt to use Wayland as default for our KDE Spin in Fedora 28. We will have
to switch soon or later anyway. With Plasma 5.12 and Qt 5.9+ the situation
with wayland should be way better and given that Plasma 5.12 is an LTS
release, then we have high chance that bugs we find are fixed within this
release cycle. If we find out that wayland is still more unusable than usable
and issues cannot be easily solved, then switching back is easy.
Fedora Workstation (Gnome) has switched long time ago, here  you can find
their proposal and even they had tons of problems at the beginning, but given
that people actually started using wayland (not just randomly testing it),
then I think it really helped to speed up the whole development process as
people were reporting issues for use cases which the devs couldn not think of
or able to test.
I'm willing of course to do all the paperwork around, propose a change, write
wiki page, contingency plan and so on and also attempt to help with fixing
What do you think about this idea?
