I have seen concerns from Nvidia users a couple of times recently so want to add some detail about that.
Most users of Ubuntu with Nvidia hardware seem to be running 24.04, just like most users of Ubuntu itself. As such they will not yet have noticed all the stabilisation work that went into making Wayland the default for Nvidia in 24.10. And as of right now in June 2025, the list of unsolved issues on Nvidia is tiny.
Nvidia itself has a list of features that are not yet available, but we don’t expect most desktop users to be concerned with those. Especially a year from now, which is the soonest most Ubuntu users will experience the removal of Xorg.
