Canonical will switch to Wayland relatively soon . Mir isn ' t even remotely close to the same level . Once Debian switches over testingunstable to Wayland by default then so will Ubuntu . The biggest problems isn ' t going to be Wayland itself , but ancillary stuff . One of the reasons Fedora is able to be ' cutting edge ' is because they are not afraid to do ' lift and replace ' on their distribution . For Example they made the switch to Upstart as soon as it was available and ran that for a couple releases . Then they were able to take that experience and apply it to Systemd and switched to that as soon as they were able . Meanwhile Debian is still in the process of transitioning to systemd and never really made upstart a fully viable option . The big difference here is that Debian wants to be everything to everybody and supports upgrades and transitioning functionality between major releases . They don ' t want to break user ' s stuff between upgrades . This means that amount of work that Debian has to do is massive compared to Fedora . It ' s the trade off between having a Linux install you can maintain and keep going for years versus something you end up reinstalling every year or so .
