Wayland. It comes up a lot: “Bug X fixed in the Plasma Wayland session.” “The Plasma Wayland session has now gained support for feature Y.” And it’s in the news quite a bit lately with the announcement that Fedora KDE is proposing to drop the Plasma X11 session for version 40 and only ship the Plasma Wayland session. I’ve read a lot of nervousness and fear about it lately. So today, let’s talk about it!
And all the arguments are like this. “It’s good to use it”, “it has features”, “it’s better code”. But it’s never “it has essential features that people need”. Because it doesn’t. If it did people would use it.
Wayland has the following features I need:
Multimonitor and other screen feature support:
mixed DPI scaling (can drag a window from a 1x screen to a 1.75x screen and have it look correct on both at the same time, even when halfway across each)
Mixed refresh rate (my center monitor is higher refresh rate than my side monitors, X11 just baselines all monitors to the lowest common denominator).
Mixed variable refresh rate (center monitor is VRR capable, side monitors are not).
HDR support soon (already exists in GameScope).
Mixed HDR/SDR output across monitors
Performance:
Lower resources
Smoother operation (can be felt in mouse cursor movements, window drags, composited animations, etc)
Better VR headset isolation compared to X11 (allows the headset to run separately and not interrupt regular monitor layout, and also lets it run freely at the correct refresh rate)
Other:
Better security between apps (yes I actually use this and count it as a feature)
App video isolation leads to pipe wire functionality, which is a bonus and makes OBS work better overall
I know for a fact I’m forgetting something because this list was longer the last time I wrote it out, but I think you get the point.
It does for me. For some reason my touchpad has really high scroll sensitivity with libinput. It’s borderline unusable. The only desktop environment that exposes the ability to change this sensitivity is plasma Wayland. AFAIK there’s technical reasons it can’t be done on xorg without hacky workarounds. This is the killer feature for me.
In addition both plasma and gnome only have 1:1 touchpad gestures on their Wayland sessions. Obviously I could use third party tools for trackpad gestures under x11 but those aren’t 1:1.
Also while I’m aware that fractional scaling on Wayland is a mess and hacky but I still find the fractional scaling implementation on KDE Wayland to be the best, followed by KDE on xorg. I need fractional scaling for things to be appropriate sizes on my laptop screen.
For my desktop I still use x11 because of nvidia but I would definitely benefit from the multi monitor improvements under Wayland since I have two monitors of differing refresh rates and it causes issues.
Congrats, you’re the 1%.
Nope, I also use it for many of these things. They’re not alone by a long shot.
If you want to continue to use X11, you are free to simply not update your machine any further. It’s unlikely you value security, so this shouldn’t be an issue for you.
You clearly don’t understand what 1% is. Do you think it means it just one person?
And you’re equally clueless about my entire argument here.
You have misunderstood me. I don’t use or promote Wayland, mainly for the very reasons you just listed. But I do recognize that it has the potential to solve real problems that are deeply embedded in X11. If/when it gets there, and fixes various deficiencies that it has today, I expect I will have a good reason to switch.
Actually, I believe it does have such features for people with certain hardware setups. I just don’t happen to have such a setup.
