Does Wayland perform better than X11?

Does Wayland perform better than X11?

If you are running production systems or systems that rely on legacy applications, then X11 will be the better choice for you. If you are looking to experiment and try out something new, then Wayland is a great way to do just that.

Does Wayland use less RAM than X11?

Over the course of all the benchmarks ran, using the GNOME Wayland session led to ~200MB higher RAM usage compared to the X.Org session.

Does Wayland use less RAM?

For example Wayland uses more RAM as full backing buffers for every window, and this actually makes moving windows around faster because it doesn’t have to ask the app to re-draw exposed areas. The only way X is using less RAM is if you run without compositing.

Is Wayland better?

Wayland is also superior when it comes to security. With X11, it’s possible to do something known as “keylogging” by allowing any program to exist in the background and read what’s happening with other windows open in the X11 area. With Wayland this simply won’t happen, as each program works independently.

Does KDE support Wayland?

With KDE Plasma 5.20, the KDE Plasma desktop environment has reached a point where nearly all commonly used features in the desktop and all major applications function in the Plasma Wayland environment on all major GPUs (including NVIDIA with the proprietary driver).

Is Wayland usable now?

>Wayland has existed since more than 10 years and it has still not been able to release a usable system. Fedora has has it on by default for about 4 years now and its perfectly usable.

Is Wayland ready yet?

tl;dr: Wayland is not ready as a 1:1 compatible Xorg replacement just yet, and maybe never will. Hence, if you are interested in existing applications to “just work” without the need for adjustments, then you may be better of not using Wayland at this point.

How does Wayland affect performance and power consumption?

The performance in those other workloads was obviously unchanged but it was the overall RAM usage and power consumption we were most curious about: Over the course of all the benchmarks ran, using the GNOME Wayland session led to ~200MB higher RAM usage compared to the X.Org session.

How much more RAM does Wayland use than X-Org?

Over the course of all the benchmarks ran, using the GNOME Wayland session led to ~200MB higher RAM usage compared to the X.Org session. The system thermal performance obviously had no meaningful difference between the X.Org and Wayland sessions.

How good is the Ubuntu desktop experience with Wayland?

The Ubuntu 21.04 desktop experience with Wayland has been quite good from testing on this system and numerous other test systems in recent weeks at Phoronix.

Is it possible to switch back to GNOME after installing Wayland?

However, via the log-in manager one can easily switch back to GNOME on X.Org if desired for testing/comparison purposes or if finding issue with the Wayland support.
