The default for EndeavourOS is X11 but 'cause I love shiny things I have tried out Wayland (last time during the holiday season) but I had a few problems - especially with one game I love - and now plan to try it out again when Plasma 6 is released in a few weeks. As I’m primarily a gamer I just have one big screen that I sit far too close to. I have read about Wayland and multi-monitors, I guess that’s something that will become better over time… I guess the question is: how much time?
