   latest 22.04 on my desktop.  You may recall last week that I simply did an   
   upgrade initially from 18.04, but I thought I'd go ahead and try a fresh   
   install.  All proceeded    
   fairly smoothly and then I found that some of my apps wouldn't work.  One   
   even had a message saying that it wasn't compatible with Wayland and to switch   
   to X11 instead; another astronomical app wouldn't display correctly as I   
   couldn't see my cursor.     
   After browsing the net, a suggestion I came across was to simply alter the   
   config file to force reboot into X11.  I was originally going to try it at   
   log in, but I didn't see any option for selecting anything present.  Anyway,   
   so now I'm on X11 and the    
   two apps that weren't working now are.  However, what's the difference   
   between X11 and Wayland as I don't see anything visually?   
      
   Wayland is a replacement for X11, and has an X11 compatibility   
   mode to smooth the transition.   
      
   But it's a bit more complicated than that.

   Compare this diagram (which does not admit that X11 exists)...

   with this diagram (which shows how some X11 can run).

   Some day, they will remove XWayland and cut off X11 compatibility. Like a   
   PulseAudio   
   removing the Alsa-compatibility plugin and causing TVTime to break (my TV set).   
   So some day, XClock and XEyes won't run.
