Oh it likely worked for quite some time before Wayland. Thing about Wayland is that it is not just a &quot;dumb&quot; canvas, but one that is to support existing UI toolkits like GTK and Qt.<p>Never mind that X does a lot more than just draw stuff. Its in charge of managing all those displays, keyboards and mice.<p>Something that various people only noticed after dabbling with Wayland and discovering that where before X was in charge of their laptops touchpad, giving them all kinds of capabilities, now GTK&#x2F;Gnome was, and thus they found themselves with a massive regression.
