GNOME X.Org vs. Wayland Performance + Power Usage On Fedora 32 With AMD Renoir Laptop

[blacknova]

It works, but it does not work well and there is no way to fix it.
The only way this could actually be solved is to write a completely new implementation of the X11 Specification, but then we can just stick with Wayland, it already has 2 good implementations.

It does work well enough for now at least. Yes, in long run we all will switch to wayland probably since were are no alternatives around or in planning. But right now, it still have enough issues to now do that at least for workstations. It might be quite all right for home users though, well, unless you have nvidia. X11 specification is out of date by decades already and while actual idea is good one to described functionality is not up to the current tasks, after all it is why Wayland was born. The problem with Wayland is that instead of updated functionality to more recent and deciding on security measures, it was decided to completely ignore benefits of server side rendering and push all rendering to client, security was updated though.

On multiple implementations - I'm not happy about it at all, how long it would be until these implementations become incompatible enough that software writers would need to take these differences into account?

wayland is so much smoother, maybe thats the reason. can it be made to be as choppy as x and have tests then.

Wayland has 0 good implementations and by design can never have a good implementation

X11 has 0 good implementations and by design can never had a good implementation.

Wayland doesn't work today, X11 does. Both are crap but one works now. Hopefully Arcan can fix this mess since Mir is dead.

X11 Just Works.

Firefox Wayland has hardware video acceleration [ while X11 doesn't ], maybe you should test power usage of that?

Even Wayland contributors work on XWayland, and much to your chagrin, people still make contributions to XServer that have nothing to do with Wayland. Maybe you want to break the news to all these devs that they are "unpeople"? https://cgit.freedesktop.org/xorg/xserver/log/


Well-informed, fact-based opinion certainly matters. You should try having one some time. It will make you feel good.
Then again, if you're just after trolling lulz, it may not be effective. Hmmm. Nevermind, just stick with spouting BS.

Sure, it is important that Legacy X11 apps run well under wayland too and I guess I can say they do well after countless hours of playing games big and small under Xwayland.
But Native Wayland is simply faster, it is especially noticeable playing extremely fast rhythm games like osu!.

To all the A N A L people on each side, just dropping this here:

Gnome Wayland Session still launch Xwayland by default, so you have the wayland apps running an the X11 apps running as well.

If you want a fair X11 only and Wayland only benchmark, wait for 3.38 or 3.40 when you can have Xwayland ondemand only and gnome-shell finally can function only with wayland.

Also remember Firefox implementation is far from optimized on wayland and performance may vary wildly depending on your mesa version(i use fedora firefox on Arch from a while ago, for example LLVM git seems to be way more responsive than when using LLVM 10 among other issue i've been dealing between releases)

This is meaningless. Launching Xwayland on demand may save a few mb of ram, but it does not influence Wayland Clients at all.
All you need to care about is if Firefox is running in Xorg, wayland or wayland/drm mode.

Contributors matter. They all moved to Wayland.

Mistakes like what?

I put that in my post already, but here it is again: they changed too much at the same time and they did so with no regard to whether the rest of the world could/would keep up.
As a rule of thumb, when you change more than one thing at a time, you're looking for trouble. Wayland found it (and I hope it manages to get out of it, eventually).

To X11 fanboys: can you explain why 30 years later I still can't use alt+Tab with Quake live in Steam? Under Wayland it works just fine.

Since we're talking two almost completely different ways to go about desktop compositors, it would be really weird if we could replicate each and every feature 1:1. Still, Wayland being the new kid on the block, it bears the burden of having to prove it to be able to walk into Xorg's shoes and not the other way around.
