My short answer:

Should I switch to Wayland?

Yes.

Applications that don't cope with wayland still work via Xwayland. Go ahead.

I've fully switched to Wayland some time ago (it could be already a year) after I learned about how insecure X really is and I honestly do not experience any issues that I sometimes see on the internet. I've been using Gnome for few months, but now I switched to KDE. I think a lot of apps are working natively on Wayland, but for other cases you have XWayland that also works flawlessy in my opinion.

One of things that was issue for me was that I couldn't use Auto-Type feature in KeePassXC, because Wayland doesn't let apps pretend to be a keyboard or capture windows as easily as X does. Funnily enough, I've managed to get it working by running keepassxc --platform xcb, but it stopped working some time ago and I'm not entirely sure why. Other thing that is a problem for me is screen sharing. Wayland doesn't allow apps to capture screen as I mentioned earlier so it heavily relies on PipeWire for this and PipeWire has its own sets of problems. It seems working correctly for the most part, but I couldn't really figure out how to share screen with sound. Not a dealbreaker for me, and a workaround would be to route audio as a microphone input for example, but it is an issue nonetheless. This is only a problem on Discord, in OBS you can easily select video and audio sources.

If you're using KDE already, you could just select Plasma (Wayland) in your display manager and play with it a bit to see if you like it and experience any issues.

You should, I think. You don't have Nvidia GPU, so you can avoid almost bugs and get better performance.

Advantages:

1. Better performance. e.g. for Firefox, @lilydjwg got double performance in wayland.
2. Better multi-screen with multi-DPI support.
3. Better maintaince. Many DE has put more and more to wayland. And many new features will only be implemented in wayland. (That's because implementing many new features will be difficult or even impossible in X11 old software architecture, as KWin developers said.)

Disadvantages:

1. Some missing feature, such as remote desktop.
2. Many bugs when you use Nvidia GPU.
3. None of the compositors except KWin and Hyprland can use input methods with electron.

I don't know which DE/WM you use. If you use Plasma/GNOME, migration is simple, just switch in SDDM/GDM. If you use i3, you can try sway, it's compatible with i3 config. If you use others, you can try hyprland or wayfire. Wayfire has fantastic animations.

I switch to wayland because I buy a new screen with different DPI... But when I switched, I found I got better performance and video hardware acceleration in Firefox (this feature was introduced to Firefox Wayland first).

If you're not having performance issues, then I don't see much reason to change. Sure, Xorg is basically in maintenance mode, but so what? Your setup works for you, so do your thing.

That said, Sway is a window manager intended to be a drop in replacement for i3 on Wayland, and is pretty close from what I hear: https://swaywm.org/

Plasma is very good with Wayland, although you might want to wait for Plasma 6, since they're apparently making several improvements, and it's due out soon anyway: https://www.phoronix.com/news/Plasma-6-Wayland-Great

You can install Wayland and switch sessions during login too, so you can check it for yourself and see if your i3 dotfiles work with Sway.

Debian (a very conservative distro) switched to Wayland by default in debian 10 if I'm not mistaken (we're now on 12).

I didn't notice the change until I tried to run a niche program that really needs X11. Unless you're doing this kind of thing, then you can probably just use Wayland. At least in Debian it's really easy to switch between Wayland and X11 by selecting the session type when you log in.

The biggest Sin by far of Wayland is making users think about the graphics stack. Does this feature or this app support Wayland or X? Does this Compositor support this GPU? Does this particular environment support this mixture of displays with this DPI? Do I need to set a particular env variable or change a setting to force this app to start in Wayland mode because under X11 its scaled funky. What works in each environment? What doesn't work between environments?

Well before you reach the end of this flow chart you have lost virtually all of your users. This transition has single-handedly set the Linux desktop back by 20 years in terms of supporting more users whose level of interest in configuration is limited to clicking a control next to their monitor and making things bigger or smaller.

A saner design would have handled scaling correctly from the start and would have had a permissive mode which just made everything from the users perspective work while progressively adding a correct UI to provide features like global hotkeys, screen sharing, only to those apps users had authorized like android. If it wasn't a such a clusterfuck to use it would have had orders of magnitude more users much earlier in the development phase and perhaps attracted more development interest as well.

No, you shouldn't.

If you need Wayland you will know, if X worked for you well and you didn't search for how to sandbox it or maybe for some other functions that Wayland has then don't switch and don't break what works for you.

You should, and you will :) X11 is legacy, and is going to die. The only question is whether you're going to try and hold on to a broken system riddled with security vulnerabilities for as long as possible until you're forced to switch, or whether you're just going to enable what is mostly already the default stack on most desktop Linux systems anyway.

• Wayland has several new features like, say, removing screen tearing, but it's not necessarily "advantages" that are the reason to use Wayland. It's sort of a redo of how graphics should work in the Linux world, and it will be the standard going forward. X11 development has more or less ceased with those developers moving to Wayland (in fact, Wayland was created by X11 developers to address issues they had with the architecture of X11). It's not a matter of should you switch to Wayland; it's a matter of when should you switch to Wayland. The answer is, as soon as you can.
• Gaming varies drastically. Some games are fine. Some games make me launch Steam via Lutris to start (not sure why it works, but it does) but run fine after. Some games can't reach higher framerates. That said, no screen tearing is a plus. When it works, Wayland is very smooth, but it doesn't always work yet. An example off the top of my head, no matter what I do, Street Fighter 6 doesn't get above 45 fps on Wayland. It's a good idea to have an X11 option as a backup still imo
• The best way to migrate is just to install a Wayland compatible DE/WM. I've used both GNOME Wayland and Hyprland extensively and they both work great. If you're used to i3 (that's what I used to use and is still my X11 backup), Hyprland is great. KDE like you have on your Desktop already works good on Wayland from what I've heard.
• I have made the switch because most of my apps can run on Wayland, and it's the future. I still have a backup in case there's a game or something that doesn't quite work for me. For instance, I can't share screen on discord. It won't even recognize the pipewire route. Thus, I've gotta switch to X if I want to do that.

You're not using any NVIDIA hardware...? Hmm, nope, that's all hardware that runs under Mesa. Give it a shot, if it doesn't work, you can always switch back.

The big advantage is improved support for new features, like adaptive sync, multi monitor support, display scaling, etc. You'll notice, new features (mostly gaming related features) will just work better on Wayland. There will be a performance hit though.

I made the switch because it's just plain better, adaptive sync works (it never worked for me on X11), oh yeah and the night color actually works. Night color on KDE just does not work on X11, AMD or NVIDIA, least for me.

Plasma is slick as butter on Wayland.

What are the advantages of Wayland?

More modern and in some cases better performance (as if Xorg performance were bad ... but hey)

What are the disadvantages?

Basically none of your current software works out of the box (you'll need a special Xorg implementation that works with your Wayland implementation in order to run non-Wayland applications). Most applications are specific to your Wayland implementation instead of a general application that runs in all environments.

why have/haven’t you made the switch?

I did not find one single floating WM that is as good as Openbox for Xorg. Also: Screen recording with OBS is problematic in some constellations.

The only advantage for the end user is better support for multi monitor systems with different refresh rates. If you don't have problems with that there's no real advantage in upgrading. Also avoid using Wayland on systems with an Nvidia GPU.

I think, it needs to be said that it doesn't have to be a hard switch. With KDE, you can just install the Wayland session and then when logging in for the first time after booting, you can select whether to start X11 or Wayland. To switch back and forth, you just need to log out and log back in.

With i3, that isn't as simple, since i3 doesn't support Wayland. You'd need to install a WM which supports Wayland + customize it, to be able to switch back and forth.

Yes switch

Wayland is not ready for gaming/streaming since it lacks a few features on obs (mainly the docks) and there is forced "vsync" on the games and you can't have tearing unless the game is wayland native and you have a recent desktop environment version on your distro thag supports it. Also some other apps may be buggy but for general usage is pretty much ready i'd say.

What are the advantages of Wayland?

The big one is proper support for diffrent refresh rate monitors and VRR. Also some security improvment and long term support (X11 probably has only a few years before development stops).

What are the disadvantages?

Its still a little buggy in some cases (especialy when using Nvidia hardware) but with an AMD or Intel GPU its more then usable. Some apps don't play nice with Xwayland but its pretty rare.

How's gaming?

I haven't encontered any major issues with games. Some games might need launch parameters but usualy you can just google it and find the answer very quickly. Performance its exactly the same as on X (maybe even slightly better)

What would be the best way to switch?

On your desktop with KDE you can just select "KDE (Wayland)" in your display manager and KDE should just run like normal but with Wayland. On you laptop you'd need to switch to a diffrent WM since i3 dosen't support Wayland. Your best bet would probably be Sway since its compatible with i3 configurations.

Why have you made the switch?

I wanted to check out how well Wayland works and found that it works fine for me, and so i decided to move. Also X was giving me issues with screen tearing and multiple monitors.

You have the hardware ideal to switch to Wayland without any headaches.

Just make sure you're running the latest stable release of Plasma.

You can also install Swaywm on your laptop and bring over your i3 dotfiles to it. Should be fully compatible.

I'd consider asking in a Linux audio or music production community (I'm not aware of any on Lemmy that are big enough to have a likely answer though). If music production is a primary use case and audio latency matters to you, almost no general users are going to be able to comment on the difference between X and Wayland from a latency perspective. There may not be a difference, but there might and you won't be likely to learn about it outside of an audio-focused discussion.

Can’t say anything about x11 but I use Nobara KDE with Wayland and it works pretty flawlessly. I found an article that’s a good jumping off point.

Why Use Wayland versus X11?

If it ain't broken don't fix it.

The only system I have where X11 is still better is a Raspberry Pi. The whole Broadcom software stack there is horrible and should diaf anyway.

Your laptop is old enough that it's probably not worth teaching the old dog new tricks. I have an 8th gen L480 that Lenovo already doesn't want to sell a new battery for.

The desktop would definitely benefit from a windowing system that understands "multi-headed" beyond being one weirdly large framebuffer. Wayland is architectured to deal with multiple screens with multiple DPIs and different refresh times.

For gaming, Wine/Proton currently targets X (with magical Xwayland protocols to bypass the worst of it), but it's going to be Wayland-native before you know it. Valve has a lot riding on making Linux/Wayland gaming better, and they're going to keep on plowing development into that. Intel and AMD are 100% on the train, and even Nvidia is being less bad about it.

I've been on sway since 2019 and I've had fewer issues than I did on i3. The performance was an immediate improvement. Feels silky smooth like x never did. Stable as a rock.

Why don't you just install it alongside X?

in my experience wayland is faster to log in and less input lag, problems are things like discord that don't implement screen record, but it work on the browser, and sometimes i need to find replacement for some apps that work on wayland(like xdotool to simulate mouse etc) i use fedora so wayland is default

Try it and pipewire to see how it works

I dove headfirst recently and switched from KDE Plasma to Hyprland. I ended up using someone else's config as a base, and I'm still tweaking, but so far, I have no regrets.

You probably won't notice a difference in day-to-day use, especially since you use Plasma. I can't vouch for performance, but you don't have a Nvidia GPU so you should be fine. The easiest way to migrate for you on your desktop is to install plasma-wayland-session, and for your Laptop to install sway and put in your i3 config.

On voidlinux with recent Plasma, I switched to Wayland a couple weeks ago. (Always change a running system, imho 😄)
I am not recording anything besides a couple screenshots here and there using spectacle (plasma native app?) so I can't say anything about this topic.
But I am using Steam and Lutris without problems with an older amd gfx card without tuning anything special.
Minor quirks here and there. Nothing fancy.

I switched recently and it's still just a tiny bit rough around the edges. People have been saying to switch for years and that can't have actually been a good idea until like half a year ago. KDE fills in some of the missing functionality with e.g. its screen sharing portal and global hotkeys emulator, so if you use something with less Wayland support/shims it might be rougher. The upside to me is FreeSync/VRR and security improvements.

Staying on X.org is fine for now if you don't need any Wayland features - Wayland is very close to being completely polished so if you really can't deal with one of its rough edges I'd check back in like a year and it will probably be seamless.

Performance is the same. Nothing has broken for me for gaming yet, and I've thrown some obscure games at it. Xwayland seems sufficient to fix any Wayland quirks that programs aren't expecting.

I switched from Arch + DWM into Artix + DWL and my Thinkpad with Ryzen 5700U doubled the battery life from 3-3,5 hrs to 6-7 hrs. Also if I close the lid, the battery won't run out as fast it was actually used. I don't know what explains all this so I don't make claims either.

I've switched to wayland full time, on amd GPU so I didn't get any nvidia problems.

Used sway and hyprland as my compositors, and a large pro was incredibly smooth desktop experience, especially when browsing when compared to Xorg. No screen tearing, just smooth as butter scrolling. Also when gaming, I found the fullscreen/borderless experience to be way less of a hassle than on xorg.

That's where the pros off the top of my head end. The cons are that it's new, so it's lacking in some software like autoclickers (can use scripts as workaround), and the security feature of applications not being able to read each others inputs, which does help against potential keyloggers but disrupts any push to use/talk applications. If you want to create an autoclicker script or use discord's push to talk, you'll likely have to bind it through a compositor with varying results, or be pretty much limited to using them in xwayland windows. And recently, it seems that my loading times of games on steam went up, though not sure how much of that is wayland's fault.

Apart from that, yeah. It's a shiny new thing that is perfectly usable, and if you want to - go for it. For your use case specifically, the cons probably won't matter unless you don't want to use a window manager, because then I'd probably stay away if I were you. The only desktop environment that supports wayland is KDE and last I've heard the experience is still rather experimental. But overall, is it worth switching for practical reasons when compared to xorg? In my opinion, no.

I can`t give you any technical details, but real-world ones -- it (drastically) decreased my cpu temps and cpu usage, while providing a slightly better performance overall.

t. Tested this on a rpi 4 while running Doom 3 (the closest of a "Crysis for rpi 4") a couple years ago. Pretty sure its even better right now.
