I must admit that I am rather lost now when it comes to X11 vs Wayland. I understand that there was a period of transition between one to another. I also understand that xscreensaver-data-extra is not the same as mate-screensaver and co.
Leaving me with this question: what should be the proper alignment? Say we put on pink glasses for a moment and want to go for "all current".
Would it be fair to say that if a end user currently wishes to take advantage of all screensaver things when it comes to Ubuntu MATE that they should be installing all of the screensaver and xscreensaver packagers?
