If you ask Google abount wayland (which is shipped with ubuntu 17.10 or fedora 26) there are some articles, which are not or no more accurate:
"You can not export any X11 application to a linux host which runs wayland"Wrong... Just login to other linux machines via "ssh -X" and run xclock or whatever. It works...
"Screenshots will not work anymore"Hmmm. Ok. X11 screenshot applications will not work anymore - but you can do screenshots with "print" (complete desktop), "alt-print" (current window) and "shift-print" (select area).
"There is no log file or other debugging information"Ok - /var/log/Xorg.0.log is not used anymore and there is no other log file. Here you can find some commands to get error/debug messages.
