One of the new arrivals what should I introduce Ubuntu LTS 22.04 it had to be that Wayland would be used with the NVIDIA driver. Until 21.10, when using NVIDIA's proprietary driver on Ubuntu it goes straight into X11, and on 22.04 it should do it on Wayland. In a last minute change, in fact it was made on the same day of April 21, NVIDIA decided that no, that it was not the time yet, so they backed down.
Computers with Intel and Radeon cards do go directly into Wayland, which is the default desktop in Ubuntu since 21.04/21.10. What is most striking is that the change details that «NVIDIA has requested that we return to Xorg by default on NVIDIA-only systems«, while the teams with other cards are already in Wayland. The last Daily Build and the beta had already made the change, which is a sign that things are going much better, but something had to happen so that in the end they didn't introduce the change in the final version.
Intal, Radeon and other machines with other graphics cards do use Wayland on Ubuntu 22.04
Although Canonical was already using Wayland on Ubuntu 22.04 in preview builds, it was NVIDIA itself that called for them to go back. Thus, the GDM (GNOME Display Manager) package was updated so that, when it detects that the proprietary driver of NVIDIA, only offer the option to enter X11. If you want to use Wayland even if you have an NVIDIA graphics card, all you have to do is use the open source driver, but this can be a problem if, for example, you want to output video through the HDMI port or get the best performance possible in some games.
Ubuntu 22.04 I arrive on April 21 with outstanding news, such as the jump to GNOME 42, greater customization or improved support for the Raspberry Pi.
