Graham: about Plasma’s X11 session

KDE contributor Nate Graham recently wrote
about the KDE Project's plans for Plasma's X11 session. He notes that
the project will continue to ensure that Plasma 'continues to
compile and deploy on X11' and isn't horribly broken. Major
regressions will probably be fixed, eventually, but the writing is on
the wall:

X11's upstream development has dropped off significantly in recent
years, and X11 isn't able to perform up to the standards of what
people expect today with respect to HDR, 10 bits-per-color monitors,
other fancy monitor features, multi-monitor setups (especially with
mixed DPIs or refresh rates), multi-GPU setups, screen tearing,
security, crash robustness, input handling, and more.

As for when Plasma will drop support for X11? There's currently no
firm timeline for this, and I certainly don't expect it to happen in
the next year, or even the next two years. But that's just a guess; it
depends on how quickly we implement everything on
https://community.kde.org/Plasma/Wayland_Known_Significant_Issues. Our
plan is to handle everything on that page such that even the most
hardcore X11 user doesn't notice anything missing when they move to
Wayland.
