Wayland's graphics system is a subset of X's - it takes the direct rendering component and leaves the others out - then combines the X compositor, X window manager, and X server into one component, when they then call the wayland compositor. But it is important to realize that direct rendering clients on X - which has been around since before Wayland was born - already work essentially the same way. The client gets a gpu buffer and does opengl rendering to it. Then they signal the display manager - whether X server or Wayland compositor - to show the buffer on screen and they do it when the time is right (e.g. vblank syncing). X does support other models too, but this is a good thing because it allows backward compatibility, better network efficiency, and simpler applications to just do simpler things too. Removing features people actually use in the real world is rarely that beneficial. So what is the major difference for graphics architecture? In X, the compositor is an entirely optional component. In Wayland, it is integrated into the display manager. That's the only real difference. What is a compositor? It is responsible for taking the images from each individual application and layering them on top of each other if you want additional scaling, transformation (like rotation), or transparency in between windows. Inside an individual window, you have all those things regardless of compositor. Traditional X servers can layer images without transparency or external scaling without any trouble at all. It only comes in when you want those fancier graphics things to happen without cooperation between windows. If you're thinking "that's not actually all that useful anyway", yeah me too. I've never used a compositor on my own system at all. Wayland claims that integrating this optional component provides a performance benefit by avoiding the cost of the additional context switch and synchronization. There's one place where that's legitimately true: exposing a window on a remote network connection. With core X, the server sends an expose event, then the client sends back a blit command from its buffer, or the drawing commands if it doesn't have one. Due to network latency, this can results in some visual lag and some flash as the server paints over a simple background color, then the client paints over it again. Wayland, of course, sees zero change here because it has zero support for this operation. Its network support - to the extent that there is any at all - is more like VNC screen share than X's remote commands. Anyway, even locally, that context switch thing is technically true but also almost certainly irrelevant since that cost is insignificant next to the time spent waiting for the vsync anyway if you use the direct rendering facility. It has a little more truth when comparing non-direct-rendering clients, but again Wayland sees zero benefit here because it simply has zero support for these use cases at all. Those programs just plain don't work. They must be rewritten to target Wayland which means they'd be forced to switch to a direct render system. But if you're rewriting the application anyway, you could just port the X application to the direct render infrastructure too. Anyway, just for background, since a compositor works with these older style applications a bit differently - those clients are not written with the extension apis in mind and assume they are going directly to the screen (well actually there's non-DRI clients that sync to double buffers too, you can render to pixmaps in the traditional api and blit it over (all core X functionality there) with a sync trigger which was provided as an extension in 1991, or you can use the XRender extension which provides an explicit double buffer function, which was provided as an extension in 2000) - the compositor intercepts the final draw to screen and redirects it to another buffer, then does the alpha blend etc on that before getting to the actual screen. It may need to guess which draws to screen are supposed to be immediate and which are already buffered and synced by the application which can introduce a bit of additional lag; it might vsync twice, for example. This is rare in practice, but when the implementation gets it wrong, you do get either a missed frame or mid-frame screen tear. But like that's an older API being used on a buggy implementation. Again, if your fix is to rewrite the application anyway, you can just use the different api and/or fix the bug in your existing implementation. There's no real world benefit. A

[snip the bit longer version] I thought that the Wayland architecture is in some way fundamentally better than X architecture, the same way D templates are fundamentally better than imitating them with a macro preprocessor, C or otherwise. But I think you said that it was not about anything that required a redesign from ground up. Like, redesigning the whole Phobos because `Algebraic` sucks instead of adding `SumType` would be our analogy of what Wayland devs did. I have to study differences in their approach more before I decide which I personally prefer.

The short version is the wayland devs were hyperfocused on one use case and missed the big picture. This led them to wrongly believe that the majority of X is completely useless legacy bloat, so instead of patching up the one use case, they threw it all out. ...then they have spent 13 years slowly reinventing it doing extension after extension and revision after revision after revision, and still haven't actually even reliably fixed the one issue they complained about... while X actually did patch it up if you opt into it (via the dri2 and sync extensions) and it does a pretty good job. They also bring up spurious security complaints - which have been around since the 90's btw but never materialized into a real problem - which are also patched via X extensions or nested servers. It could certainly be better but a version 1.1 or 2.0 of the security extension could realistically fix that up, no need to throw everything out. (Notice how Microsoft made similar changes in Windows without a significant breakage of backward and interoperation compatibility.) So they broke everything for no benefit. Again. It is just like the broken audio stuff. And then it really annoys me that the wayland proponents are rarely well educated on X, saying things that are just untrue. So that ups the flamewars to 11.

I for one will *not* be happy about X being dropped in favor of Wayland, esp. since the latter is not (yet?) at feature parity (or better) with X.
