From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Alternatively, instead of reading a Phoronix article that has a couple of short snippets from a much longer blog post, you can read the original blog post yourself to see the full context.
Edit: Also, it is worth noting that the author of the original blog post had previously written another relatively recent post criticizing the way in which Wayland was developed, so it's not like they are refusing to see its problems.
One of the specific issues from those who've worked with Wayland and is echoed here in Nate's other post that you mentioned.
Wayland has not been without its problems, it’s true. Because it was invented by shell-shocked X developers, in my opinion it went too far in the other direction.
I tend to disagree. Had say the XDG stuff been specified in protocol, implementation of handlers for some of that XDG stuff would have been required in things that honestly wouldn't have needed them. I don't think infotainment systems need a concept of copy/paste but having to write:
Some_Sort_Of_Return handle_copy(wl_surface *srf, wl_buffer* buf) {
//Completely ignore this
return 0;
}
Some_Sort_Of_Return handle_paste(wl_surface *srf, wl_buffer* buf) {
//Completely ignore this
return 0;
}
Is really missing the point of starting fresh, is bytes in the binary that didn't need to be there, and while my example is pretty minimal for shits and giggles IRL would have been a great way to introduce "randomness" and "breakage" for those just wanting to ignore this entire aspect.
But one of those agree to disagree. I think the level of hands off Wayland went was the correct amount. And now that we have things like wlroots even better, because if want to start there you can now start there and add what you need. XDG is XDG and if that's what you want, you can have it. But if you want your own way (because eff working nicely with GNOME and KDE, if that's your cup of tea) you've got all the rope in the world you will ever need.
I get what Nate is saying, but things like XDG are just what happened with ICCCM. And when Wayland came in super lightweight, it allowed the inevitably of XDG to have lots of room to specify. ICCCM had to contort to fit around X. I don't know, but the way I like to think about it is like unsalted butter. Yes, my potato is likely going to need salt and butter. But I like unsalted butter because then if I want a pretty light salt potato, I'm not stuck with starting from salted butter's level of salt.
I don't know, maybe I'm just weird like that.
I don't think infotainment systems need a concept of copy/paste but having to write:
Having lived through the whole "phones don't need copy and paste debate", which fortunately got solved by now having it everywhere I'm in the camp "just stick that everywhere, just in case somebody might use it one day"
Wayland has fixed so many head-scratching issues I would get running 6 monitors on 2 GPUs under X11. I'd often end up with missing monitors, placed in wrong spots that I'd have to rearrange every reboot until an update would come through that would fix it again for a few months, then all over again.
Since I moved to wayland, everything just works. When it doesn't, it's not a display server issue, it's something physical. I just had a couple monitors fail to show up and thought "oh hell, it's back to this, eh". But I open the tower, seat the offending GPU better, and everything comes up like normal, and all the screens are in the right position, it just remembers.
Anyone that thinks X11 is still superior probably runs on a laptop with a single screen.
man it crazy I switched to Wayland on my laptop and docking to 3 monitors just worked on Wayland and it would remember all my monitors settings
I hand like 2 or 3 scripts setup to try and manage that on x11
Over on Nate's other blog entry he indicates this:
The fundamental X11 development model was to have a heavyweight window server–called Xorg–which would handle everything, and everyone would use it. Well, in theory there could be others, and at various points in time there were, but in practice writing a new one that isn’t a fork of an old one is nearly impossible
And I think this is something people tend to forget. X11 as a protocol is complex and writing an implementation of it is difficult to say the least. Because of this, we've all kind of relied on Xorg's implementation of it and things like KDE and GNOME piggyback on top of that. However, nothing (outside of the pure complexity) prevented KWin (just as an example) implementing it's own X server. KWin having it's own X server would give it specific things that would better handle the things KWin specifically needed.
Good parallel is how crazy insane the HTML5 spec has become and how now pretty much only Google can write a browser for that spec (with thankfully Firefox also keeping up) and everyone is just cloning that browser and putting their specific spin to it. But if a deep enough core change happens, that's likely to find its way into all of the spins. And that was some of the issue with X. Good example here, because of the specific way X works an "OK" button (as an example) is actually implemented by your toolkit as a child window. Menus those are windows too. In fact pretty much no toolkit uses primitives anymore. It's all windows with lots and lots of text attributes. And your toolkit Qt, Gtk, WINGs, EFL, etc handle all those attributes so that events like "clicking a mouse button" work like had you clicked a button and not a window that's drawn to look like a button.
That's all because these toolkits want to do things that X won't explicitly allow them to do. Now the various DEs can just write an X server that has their concept of what a button should do, how it should look, etc... And that would work except that, say you fire up GIMP that uses Gtk and Gtk has it's idea of how that widget should look and work and boom things break with the KDE X server. That's because of the way X11 is defined. There's this middle man that always sits there dictating how things work. Clients draw to you, not to the screen in X. And that's fundamentally how X and Wayland are different.
I think people think of Wayland in the same way of X11. That there's this Xorg that exists and we'll all be using it and configuring it. And that's not wholly true. In X we have the X server and in that department we had Xorg/XFree86 (and some other minor bit players). The analog for that in Wayland (roughly, because Wayland ≠ X) is the Compositor. Of which we have Mutter, Clayland, KWin, Weston, Enlightenment, and so on. Which that's more than just one that we're used to. That's because the Wayland protocol is simple enough for these multiple implementations.
The skinny is that a Compositor needs to at the very least provide these:
And that's about it. The specifics of how to interface with hardware and what not is mostly left to the kernel. In fact, pretty much compositors are just doing everything in EGL, that is KWin's wl_buffer (just random example here) is a eglCreatePbufferSurface with other stuff specific to what KWin needs and that's it. I would assume Mutter is pretty much the same case here. This gets a ton of the formality stuff that X11 required out of the way and allows Compositors more direct access to the underlying hardware. Which was pretty much the case for all of the Window Managers since 2010ish. All of them basically Window Manage in OpenGL because OpenGL allowed them to skip a lot of X, but of course there is GLX (that one bit where X and OpenGL cross) but that's so much better than dealing with Xlib and everything it requires that would routinely require "creative" workarounds.
This is what's great about Wayland, it allows KWin to focus on what KWin needs, mutter to focus on what mutter needs, but provides enough generic interface that Qt applications will show up on mutter just fine. Wayland goes out of its way to get out of the way. BUT that means things we've enjoyed previously aren't there, like clipboards, screen recording, etc. Because X dictated those things and for Wayland, that's outside of scope.
That's my problem with this. It tries to be a desktop display server protocol without unifying all desktop requirements. Sure, X11 is old and have unnecessary things that aren't relevant anymore, however, as someone who builds their own DE, (e.g.: tiling window managers) I see it as the end of this masterrace. Unless everybody moves to wlroots. Flameshot, for example, is already dealing with this, having at least 5 implementations only for linux, and only wlroots and x11 are standards.
Also, imo, having windows in windows is useful when you want to use your favourite terminal in your favourite IDE. But as you said DEs can implement it simply. Let's say wlroots will implement this but others can decide otherwise. And for those the app won't run.
Another example, that affects my app personally, is the ability to query which monitor is the pointer at. Wayland doesn't care having these so I doesn't care supporting wayland. And I"m being sad about this because X is slowly fading away so new apps will not run on my desktop.
Moreover with X11 I could write my own hotkey daemon in my lanuage of choice, now I would have to fork the compositor.
Do I see it wrong?
Every change will bring it's fair share of complainers, not much we can do about that. LILO to GRUB, SysV to systemd and now X11 to Wayland. No one is forcing your hand (unless you use a pre-packaged distro like Ubuntu/Fedora, in which case you go with whatever the distro provides), keep using X11 if you want stability, if you wanna dip your toes in bleeding-edge software and increase it's userbase to show hardware manufacturers that their drivers need to be updated (I'm looking at you, NVIDIA) then feel free to mess around.
Eventually the day will come when Wayland apps will simply not launch on X11 and you'll migrate too.
I'd say that's already becoming the case in a few places. Hyprland isn't just "Wayland good", it's "You should use Wayland good".
Yes, I know the devs behind it act like pissants. That's bad and I'm sorry for liking their software. I use Emacs too and RMS was kind of an asshole. Hell, I use Lemmy even though one of the devs has slighted me on more than one occasion.
Every change will bring it’s fair share of complainers
sometimes the complainers are right and sometimes they aren't
And when they're right, it's usually addressed. I say usually because GNOME exists.
AFAIK, Fedora is the only distro that's getting rid of X11 support, the other distros are still packaging it AFAIK.
after more than 25 years using linux I could not care less about those dramas, when my distro will drop xorg I'll switch and that's it. I've got way too much stuff to implement myself already, there is no time for that. I mean, I've even embraced systemd...
Most distros use Wayland now and you probably won't notice a difference.
I wish that was my experience, but Nvidia drivers on KDE Wayland have had a lot of oddities and issues that have caused me to go back to Xorg every time I've tried (12 times and counting). Wayland is a good move in the right direction, and I look forward to it, but it's still being implemented.
That's less about Wayland than it is about shortfalls in nVidia driver development. Exactly like Nate's example in the blog post.
Oh boy, 102 comments. Knowing Phoronix, I bet those are a treat to read.
Reading angry boomer Linux comments is one of my most favorite hobbies
Anecdote, I know, but for my use cases, Wayland just isn't there yet- I wind up with far more random bugs and less battery life. I don't pretend to know why, I'm a pleb non-developer, but until that's resolved I'm still stuck on X. I'd love to use the new shiny thing of The Future™, but not at the cost of stability and usability.
I think that given how frequently this argument is brought up (and it is of course true about it not being completely there yet) so this is just my opinion on the situation (and I am not a dev so I am fine with being wrong and corrected). It is kind of needed for more projects/distros to start actively using it. As a lot of the stuff kind of needs the band-aid ripped off to start forcing it to get there faster at this point. Otherwise it just keeps being held back as people on the coding end of things will keep focusing on X11 issues instead of getting things ready for Wayland.
Kind of like the conundrum of mobile OSes that aren't Android or iOS. It is hard to get people/companies to even try the new OS because the lack of apps (specifically the most common ones used by the most people). But app devs don't want to spend time re-building or starting new apps for an OS that isn't being used (or on devices people are buying). So at a certain point it needs both sides to interact and make progress. The OS needs the apps more at this point, and getting feedback and data from those devs makes it known where things are and aren't working. But it is also true the devs for the apps might end up finding out the OS is actually easier to work with compared to what they have been doing/dealing with on Android/iOS.
Getting a replacement for X11 has been needed for a long time as the OSes and features keep needing something new to better work for how computers have advanced. And it isn't something that many devs would want to take on given how easy it is to just use what is already known. Since Wayland has finally gotten to the point it is now, it is time for more devs to start learning/moving to the new thing to get attention to the stuff that they need. The hardest part is this in between period for users as it can and will cause random issues (like the ones you have seen). Stability is important, but Linux is great because there will always be distros and projects that keeping the old thing running well is the main objective. So we are in some great times for the new to be pushed hard so it can become the stable future needed.
I don't see why we need convincing that Wayland's better. Most Linux users either use it currently or are possibly looking to switch in the future. The other people who are not are likely going to use X for eternity
I think real X11 fanboys are almost non-existent. Wayland wouldn't be so rejected if it wasn't that it still has a lot of compatibility issues, I think most people just want everything to work and don't care whose fault it is.
Yeah I don't get why some people would think sticking to X is fanboyism. Nobody likes X, let alone love it. Most people's relation to X is pragmatic, it's "it works and does everything I need".
If anything, fanboyism is telling people they have to use Wayland when it doesn't yet work for what they need it to do.
Just keep improving the damn thing and people will switch when it's ready. There's no convincing needed.
It's super impressive to see Wayland having its big breakthrough moment. I remember reading about Wayland 10 years ago and worrying it was going to end up as a dead project.
Until my distro forces wayland on me I'll stick with xorg+XFCE. I've played with sway and hyprland but I need my application choices to actually work well. (no I'm not going to list them).
As for the cube desktop in the image: We had this with compiz and learnt then that this is pointless.
Why are we back there?
I love Wayland until I don't. I honestly don't think about it, it gets out of my way and my system is stable, until I go to use something like scrcpy that just doesn't work at all. Luckily, the amount of things that straight up don't work is shrinking.
