I remember an awful lot of posts happening around the time the decision was made to default to the Wayland protocol for the f40 KDE spin.
I sure came away from those discussions understanding that, while Wayland would be the default, it would remain possible to install X11 and continue along as before with it, too. I was pretty sure that they hadn't banned it, just discontinued making it the default.
Are you saying that that's not true?
@jrredho "the transition to KDE Plasma 6 will also include dropping support for the X11 session entirely, leaving only Plasma Wayland as the sole offered desktop mode. "
