That is a great exaggeration. Well, it depends on what you mean by “overtime”, if you mean decades, then sure, every software will be obsolete in decades. But for the foreseeable future, X11 is still very much alive and kicking and I don’t see that changing any time soon. Wayland has been around for a long time (not nearly as long as Xorg, but still, a decade or so), and it still isn’t fully functional… It may very well become obsolete before it reaches maturity. Maybe even before X11, who knows? Difficult to say what the future will bring.
Nobody knows what will happen in the future. I would be more present-oriented. It’s not like using Wayland now will help you use Wayland in the future, you can switch back and forth whenever you want to… Do you currently benefit from Wayland’s allegedly better multidisplay support?
EDIT: doesn’t look like it:
What are some other concrete benefits you get from running Wayland? I always consider switching to Wayland, but my list of pros and cons is very asymmetric: I can easily fill the cons column, but I have barely anything to put for the pros. Fortunately, it’s super easy to switch between the two.
Well, the solution to your UI problem is pretty obvious, the fact you don’t want to hear about it is another problem that I don’t have a solution for.
Neither do I, the answer to that is pretty clear. I’m just trying to understand your stubbornness in using something that clearly doesn’t work for you, when the obvious alternative exists. That is all.
