ubuntu 21.04 will use wayland by default - ubuntu 21.04 will use wayland instead of x.org by default

In This Video We Are Discussing About Ubuntu developers made Wayland the default session in Ubuntu 17.10 (which was, notably, the first version of the system to use the GNOME Shell desktop). However, things weren’t perfect at the time so developers chose to switch back to Xorg for the subsequent release.

Ubuntu is going to be trying to switch over to using Wayland by default for the current Ubuntu 21.04 cycle to allow sufficient time for widespread testing and evaluation ahead of next year's Ubuntu 22.04 LTS release.

Canonical engineer Sebastien Bacher announced today they will be trying again for Ubuntu 21.04 to enable Wayland by default, four years after they originally tried but reverted back to using GNOME on X.Org for Ubuntu 18.04 LTS and since that point. Ubuntu with GNOME Shell on Wayland has been available as a non-default choice but the hope is now in 2021 they are ready to comfortably switch to Wayland.

In recent years GNOME on Wayland has improved with its Pipewire desktop sharing support among other improvements. For Ubuntu 21.04, users of the NVIDIA proprietary driver will still see the X.Org session by default but they hope in time for Ubuntu 22.04 LTS will be better NVIDIA Wayland support.

Details were relayed a few minutes ago on Ubuntu Discourse.

Ubuntu 21.04 is sticking to GNOME 3.38 rather than moving to GNOME 40 as the default desktop environment this cycle. It will be interesting to see if they stick with Wayland by default (for non-NVIDIA setups) for this spring release. Given the shift, I'll also be working on some new X.Org vs. Wayland benchmarks shortly.

Other distributions like Fedora Workstation have already been defaulting to Wayland for years with the GNOME on Wayland code being incredibly fit at this stage. The KDE Plasma code is also becoming in very good shape with Wayland and by Plasma 5.21 will hopefully be production hardened. Paired with NVIDIA DMA-BUF improvements and the new Vulkan extension work coming around enhancing compositor support, perhaps 2021 will finally be the year of the Wayland Linux desktop?

Explaining the situation, Bacher said:

“In the Ubuntu 17.10 cycle we tried Wayland as the default session but we didn’t feel confident at the time it was ready yet for an LTS. Things improved since, some of the blockers we found back then got resolved (desktop sharing), and that’s where the upstream focus is going. We believe now is the right time to try again, it should give us enough time before the next LTS to get proper feedback and sort out issues.”

By shipping Wayland with Ubuntu 21.04, the company has a whole year and another Ubuntu release in October to find any major issues and get them fixed. This additional time, compared to when it was attempted before, should be long enough to ensure a stable Wayland release with Ubuntu 22.04 LTS.

Know?

Ubuntu tried to use Wayland as the default display server in Ubuntu 17.10 and burned its hands. It looks like, Ubuntu is willing to try Wayland as default once more with Ubuntu 21.04 Hirsute Hippo.

For those who are unware, a display server is an underlying utility that enables your operating system to have graphical capability.

Linux distributions have been using the legacy Xorg display server for decades. There are a couple of new, next generation display servers and Wayland is one of them.
