Probably everyone that is interested in the Linux desktop has heard about Wayland. It's the next big thing, the replacement for X.org, a solution to a lot of woes in terms of performance and graphics on Linux. And still, it has failed to materialize, over and over, and is still not the default on many big distributions, like Ubuntu, or Linux Mint. Let's see what Wayland is, and how ready it is, right after this!

Wayland is, in itself, just a protocol. It's not a program, or a replacement for the old X.org display server. This protocol has to be implemented by a compositor, which will display the application's content on the user's screen.
Currently, a lot of distributions use X.org, the very old display server that has served us pretty well for ages. The goal of wayland is to put this old beast to pasture, but for what benefits ?
First, let's take a look at how X.org works. This old thing, dating back to 1987, the blessed year of my birth, by the way, is a multi-layered process:
First, you have your display server, or the X server. It's the central platform to communicate with the clients, like the applications you're using, and the compositor, which displays the windows for these apps themselves. This server is interacting with clients, which are basically your applications, but also with a compositor, which is your window manager, like Kwin on KDE, or Mutter on GNOME.
It's a sturdy process, but it introduces a lot of delay, with some back and forth betwen the server, the compositor, and the application itself.
Wayland has a simpler model, because in Wayland, the compositor IS the server as well.
This means that, in our example, the application opens, tells the compositor that it wants a window, and the compositor gets all the details from the app in one go, decides what to do with the window, and tells the app to draw itself. Yep, on Wayland, the applications also have to do their own rendering on the screen: they manage their own titlebars, their own drop shadows, everything.
This is why you can't just switch GNOME or KDE from X.org to Wayland: the pieces that compose the desktop environment don't play the exact same role on both solutions. On Wayland, the compositor doesn't draw the windows, the app themselves do, so you have to update the window managers to become compositors that don't do any drawing, and you have to update the toolkits, GTK and Qt, to let them draw stuff themselves.
Then there's the issue of the graphics drivers: the Nvidia drivers, the open source AMD or Intel drivers, these were written to send information back and forth with X.org, not with a wayland compositor.
So they also have to be updated to work with that new model. This is already the case, as the open source Mesa drivers, which cover AMD and Intel, already support wayland using a solution called GBM. Nvidia, on the other hand, decided that they had a more efficient solution called EGL, which has to be supported separately by the wayland compositors.
Since Nvidia doesn't seem to be willing to update their driver to use GBM, for nvidia drivers to work with wayland, desktop environments have to also support EGL, which is an extra burden, and also explains why Nvidia drivers are hit or miss when using Wayland.
So, where is Wayland? Well, it's already very well supported:
- GNOME supports Wayland, with Mutter, its window manager and compositor
- KDE supports Wayland as well, with Kwin
- Both GTK 3.20 and QT 5 support wayland out of the box
In terms of distros, Fedora already uses Wayland as the default, if the drivers permit it, and has been since 2016. Red Hat Enterprise Linux 8 also uses Wayland as the default, and Debian does so as well, for their GNOME sessions. Manjaro also defaults to wayland for the GNOME sessions, if the drivers allow it.
Some programs that were made specifically to work with X.org don't work on wayland-based systems, especially games.
For that use case, Wayland developers have a solution: as wine or proton expects to run in an X Server, Wayland provides the ability to run such a server inside of Wayland, as a client, this is called Xwayland.
The performance of Xwayland, however, seems on par with just running a game on X.org, as demonstrated by Phoronix early this year:

@GeraldOSteen 3 жыл бұрын

@@bobdinitto Not really; the entire filesystem tree was designed to run across multiple systems, so it was quite consistent. The root filesystem(/) was run locally, containing only what was necessary to get the local machine up & running and then the /usr tree was mounted remotely(because it often resided on a larger server mounted via NFS; hence the name 'Unix System Resource', which for some reason is disputed). When X was launched, it set the DISPLAY environment variable according to your IP(and screen) so that when you ran 'xterm' or some other X client it automatically connected to the correct display. The X server running on your local machine provided the X services(hence it being the 'server') and you were running client applications which just happened to be mounted on a remote filesystem. X didn't turn it around on its head, it's just not the way we tend to run our systems these days so it's a pretty foreign concept now. Set up a few Raspberry Pis as dumb terminals mounting /usr from a central server and it suddenly makes a lot more sense again.

@tejing2001 3 жыл бұрын

The explanation on the difference between Wayland and X got a little muddled there. Historically, there were a lot of huge differences, but in terms of how things work in a modern environment, programs talk directly to the graphics card to render their content into a buffer, that buffer is handed off to the compositor, which further tells the graphics card how to put all those together into the final appearance of the screen, which then gets displayed. This is true for both X and Wayland. The difference is that in the X case, X is uselessly in the middle of almost every step of that process. Since compositors became the norm, the actual value provided by the X server has become quite small. It's just a middleman now, and it's time to cut it out... in theory. The current state of Wayland seems to me to be pretty much summed up by the old joke: "it's 95% done, now we just have to do the other half!" When replacing something that deeply embedded, there are always more complications than you could possibly predict. We'll get there. It'll just take time... not that NVidia is helping any with their "the whole world should do everything our way" attitude.

Few fun facts: X was implemented as client-server because at the time shared libraries did not exists. Also Waylands huge advantage (+ small performance) is due to fact that apps do not receive clicks and key presses from other apps. In X (also Windows last time I used) every event is sent to every application(client). Each application will filter event it is interested by itself. Effectively, each app can be a key-logger.

Currently my X11 solution is to just run the UHD screen in a smaller non-native resolution...

EGL is something completely different. What he meant was EGLstreams, a part of the EGL spec that was not originally meant for Wayland and not used by any standard driver compatible with Wayland. Only Nvidia did go that route and contributed all the code to make that weird thing work on existing desktops themself. Wayland surfaces use EGL to draw, Android for example also uses EGL to draw. en.wikipedia.org/wiki/EGL_(API) "EGL handles graphics context management, surface/buffer binding, rendering synchronization, and enables "high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs."

When you design a protocol (X11) which survives so many generations of new hardware, then it is an excellent design. Really excellent. It is a pity that your drawing does not put X on the right spot (should be between application and display always), the window manager communicates via X client to the screen as well. The X-Server is directly next to the rendering hardware: knows about chipsets, screen resolution etc. It offers data exchange protocols from extremely simple and old, up to OpenGL. The client negotiates the optimal protocol. So: any X client (even 30 years old) can address any X screen (even bought yesterday) and vice versa!!! No upgrade problems ever! From any internet connected system to any internet connected screen!

@TheLinuxEXP 3 жыл бұрын

Probably a very efficient design to solve a problem 99% of people using computers today don’t have, and don’t care about :) The main use case is one screen for one device, and that screen directly linked to that device. X can solve many problems, but no one has these problems anymore, apart from some niche use cases.

@@TheLinuxEXP When the screen hardware is on the same server as the client software, then X uses shared memory to communicate. Remote display is a feature which does not hinder anyone.

However, it's quite hard to beat with a full implementation which has seen >30yrs of fine-tuning. We'll see,

You forgot to talk about wayland supporting HiDPI scaling by default, as well as multiple scale factors on different monitors, making it easy to have a multi-monitor setup.without having to scale each one with xrandr. This is a very important feature for people who have new laptops with HiDPI displays.

I'm a huge fan of your videos sir. They are so poignant and precise. I wasn't at all surprised when I finally found out you are a teacher. As for Wayland I recently ran it without knowing it on Ubuntu Web Remix so for basic things it's obviously fine. I didn't take the time to test things out though. The main thing that I used to worry about missing is X11-Forwarding via SSH, but I wouldn't be surprised if that's working fine now. Personally I think X11 has been pretty impressive for Linux on the desktop. We've had major changes to graphics and gaming with X11 providing a decent experience throughout, but I suppose it could be holding gaming performance back in some ways too without really knowing it.

Definitely the lack of feature parity is what holds it back. I'm kinda surprised after all these years of selling Wayland as the next best thing it still lags so much behind Xorg... IMO one of the problems for Wayland's attractiveness is that the much maligned delay involved in the X11 design isn't really noticeable. Wayland has other benefits, but that one in particular is hardly a selling point (just as X11's complexity), yet it's usually the first one to be brought up. Also, the fact that something is a zillion years old doesn't automatically make it or its code any worse or harder to maintain. Linux itself is 30 years old, for example. I'd appreciate if the community would stop using "this thing is old" as an argument. The problem is how it has evolved, not its age.

@Pantymonium 7 ай бұрын

If something works pretty for decades, it may means that it is just robust. Of course, it does not mean that new think cannot be better. But sometimes good enought is just ok. Another aspect: Wayland does not offer network transparency by itself, and many apps works very bad throught the network. For gamers it may be not so important, but for companies, engineers and scientist it is crucial.

4:08 “You don’t have a server ... the compositor is the server”. Yes, you still have a server doing the display, just as with X11. The difference is that it is much simpler: its main job is to put a bunch of pixels on-screen, composited in some way with the pixels already there. X11 is also a graphics library (and also, at one time, a font server -- but thankfully that’s long gone). Nowadays it’s recognized that graphics rendering (including text rendering) is all best done on the client app side, while the display server just concentrates on showing the resulting pixels.

I like Wayland and I think it is the future, but I'm not quite ready to switch yet. Luckily I use KDE Plasma which supports Wayland, whereas most DEs unfortunately don't, but Plasma on Wayland still has some annoying bugs or crashes that need to be sorted out (some of which already are fixed in the git version), plus I'd like to have built in touch gestures support. Also, I hope to see native Wayland support in OBS soon. There are some patches and plugins to make it work but it is not ideal. And Wine is working on native Wayland support, which should hopefully reduce or negate the performance hit of using Wayland for gaming. But one of the benefits I see with Wayland, besides speed and security, is that they could hopefully implement higher color depths (e. g. 10 bits per color) and HDR without making everything explode like 10 bit color in X11.

@@freedomgoddess: They never killed Mir. It's going as strong as ever. They decided that developing for Mir should be done without reference to internal protocols because developing permanent standards is a very time-consuming thing. So with Mir, they said you should rely on the Mir API and let Mir figure out protocols. Now, Mir is "openly" Wayland. Unity 7 and Unity 8 are entirely different things. Unity 7 deeply depends on X11, which won't make any sense moving to Wayland, so moving it to maintenance mode and turning it over to the community was a smart decision. Neither were killed, unless you consider all Free Software that's not backed by commercial entities dead. Unity 8 was a different matter. Its primary reason for existence was convergence, which depends entirely on the Linux community _wanting_ to exert pressure on Google and Samsung, which was something the Linux community was totally unwilling to do. I still think Linux users made a big mistake when they decided that Samsung phones should not be allowed to run Mainline Linux. Most of them probably didn't understand what they were refusing. I personally own a Pinephone, but it's obviously quite weak compared to the Galaxy S8 or S20 and that's all because of drivers that we're not allowed to have. Canonical and Red Hat are the only ones who could bring it to us, but the infighting prevents it from happening. The only real hope is that IBM decides to go into phones, but I don't see that happening.

@@freedomgoddess: Mir is actually quite popular for things like info-screens that you may see on buses and things like that and it's actively developed.

I think Xfce has talked about it too. Unity 7 is still quite popular and it's more reasonable to consider it stable than dead. But because it is based on Compiz, which is specifically designed to circumvent the problems with X11, it will never be ported to Wayland. In that regard, you can consider it dead. It will probably not be usable 30 years from now. There's never any reasonable way to say Unity 7 / Unity 8. They have nothing in common. It's like saying "I'm tired of the Windows 10 / Mac OS system". It just doesn't make any sense.

Yea, as Nick correctly notes - one of the main issues with developing a desktop environment for Wayland - especially if you want to write your own compositor - is that a lot of stuff that we used to get "for free" from the X server, such as a clipboard implementation, you now have to implement yourself. So everyone that complain that there are too many competing X servers (Hi early 2000s 😜), now every desktop environment has to implement its own server. Yay! This is open source, so someone smart decided to make things easier and the wlroots project develops a set of common tools to make it easy to write (at least simple) Wayland compositors without needing to re-invent the wheel, but neither GNOME nor KDE are using these - they both implement everything themselves. GNOME is much farther ahead than KDE on that and is actually the major producers of new Wayland protocols to handle things that are needed and Wayland - on purpose - did not design for: such as screen capture (hi KZfaq streamers 👋👋).

They are trying to enforce the idea that they are owners of all free/libre software. For example, there are puff pieces where Xorg is mentioned as personal property of RedHat.
