You can add elementaryOS 0.4.1 to the working distrosnewest ubuntu
it's really just based on Ubuntu 16.04 LTS and I've only tried it within a VM but it does its job
(no comment on latency or performance because VM tests are not to be trusted a lot but it worked just fine)
Is there actually a distro or repository where one can test wayland?
I'm actually really curious how (bad) it actually turns out to be (for playing osu) in its current state
