I know I could duckduckgo it, but I think we’re at the stage at lemmy where there’s space to ask basic questions.
What is it? Why does it matter? Users at which lunix proficiency level should care about it? Is it just yet another competing standard or is x actually going to die?
I think this is the perfect post to bring up XWayland.
That being said, I haven't used it yet (so I can't comment on whether it works flawlessly)! Can anyone elaborate on their experiences with it? I'm curious on it and don't have my hands on a Linux machine at the moment
Wayland is the fancy new standard that never seems to stably work for me on any of my machines :( Thanks for letting me revert to X in the login screen, GNOME.
Great answers here. I’d just like to add that X and Wayland are not completing. In fact, most of the Xorg devs are the ones working on Wayland. You can find Wayland mentioned in the Xorg Foundation Website.
On top of what other said, the wayland project also maintains the wayland protocols repository which includes additional protocols that are approved by a “committee” that includes representatives from wayland protocol implementations (wlroots, kde , gnome , smithay etc). for example now they are working on color management.
There appears to be a consensus among people working on window manager implementations that X has to go and wayland is the future.
Wayland has technical benefits, if you want the nitty gritty details see this.
Basically X11 is bad IPC at this point.
Also be careful with what you read online, I see misinformation about it relatively often.
You’ve already gotten great answers on what Wayland is, but as far as who should care:
Mainly developers and users with niche workflows. People with NVIDIA cards should care a little as initially NVIDIA did not support Wayland, but NVIDIA drivers are catching up so this should continue to improve. Most users should just switch when their DE switches.
Explained by someone that doesn’t know the technical side super well.
1: It’s a new protocol for displaying. The main difference from X11, as I understand it, is a simplification of the stack. Eliminating the need for a display server, or merging the display server and compositor.
2: Some things impossible (or difficult) with X11 are much better supported in Wayland. Their not necessarily available, as the Wayland protocol is quite generic and needs additional protocols for further negotiation. Examples are fractional scaling & multiple displays with differing refresh rates.
Security is also improved. X11 did not make some security considerations (as it is quite old, maybe justifiably so). In X11 it’s possible for any application to “look” at the entire display. In Wayland they receive a specific section that they can draw into and use. (This has the side-effect of complicating stuff like redshifting the screen at night, but in my experience that has fully caught up).
3: If you’re interested, are in desktop application development (but I have no experience in that regard) or have a specific need for Wayland.
4: I think X won’t die for a long long time if “ever”. I’m not super familiar with desktop app development, but I don’t think it requires more work to keep supporting X.
On the other hand, most of the complaints about Wayland I’ve heard were ultimately about support. At some point, when you’re a normal user, the distro maintainer should be able to decide to move to Wayland without you noticing, apart from the blurriness being gone with fractional scaling.
I’m not super familiar with desktop app development, but I don’t think it requires more work to keep supporting X.
It doesn’t depend that much on desktop application developers, but on GUI toolkit developers. It does need more work for GTK and Qt devs to support both. But the outcome will likely depend not that much on ammount of work as on “political” decisions. RedHat are now somewhat actively forcing Wayland in their distros. They also have their impact on GNOME, so it’s not impossible that due RedHat’s decision GNOME and then GTK (that is now developed mostly by GNOME developers, despite being GIMP Toolkit initially) will ditch X “just because”.
End user Application developers usually don’t deal much with Wayland or X — they just use toolkits (GTK or Qt for the majority), and toolkits do all the under the hoof work for them.
