X11 used to provide separate displays, but at some point due to hardware changes (and quite probably due to prominence of intel hardware, actually) it was changed to merged framebuffer with virtual cut out displays.
In a way, Wayland in this case developed a solution for issue its creators brought into this world first
- goosedragons 2y agoIt can still provide seperate displays. The problem is you couldn't do something like drag a window from display 1 to 2°. IIRC it's also annoying to launch two instances of a program on both displays. The hacky merged framebuffer thing is a workaround to these problems. But you can have independent DPIs on each display. ° For most programs.
- robinsonb5 2y agoYeah there were certainly tradeoffs. It's much harder to use separate displays now, though - last time I tried, I could address the two displays individually (":0.0" and ":0.1") if I launched X on its own, but something (maybe the display manager?) was merging them into a single virtual display (":0") as soon as I tried to use an actual desktop environment. (This was was Mint 20, MATE edition, a few years ago - I gave up and reverted to a single-monitor setup at that point.)
