I wasn’t clear. I meant that the issues with X crashing were usually driver issues. I have no idea about Wayland - I don’t use it since it doesn’t do what I want by design.
X does the job well enough to be invisible to most people. Yes, we need a clean start in order to move forward efficiently (lots of assumptions about computer displays from the 80s no longer apply), but it’s good enough for most people’s needs.
Why bother with a display server? Some people - like myself - actually use that functionality. It’s not part of the design for Wayland. Personally, I think that’s a mistake - especially as things become more cloud-based - but I’m obviously in the minority.
