GNOME 43 in preview versions it has been available for a long time. right now you can test the beta, but it is not recommended to use it, nor is it an easy way, on equipment that we depend on. What the project recommends is that you install GNOME OS, a pseudo-operating system that receives all the new features as soon as they are ready, but you can also try it by installing a preview version of some operating systems.
One that GNOME 43 will use is Ubuntu 22.10, who this week has uploaded to his repositories the beta of GNOME 43. It is worth mentioning that in my case (GNOME Boxes in Manjaro KDE) it stopped working, it does not start and everything stays black, for things like these it is not necessary to use it in the main installation, but the Live Sessions in the same configuration, (and on new installations if the extra software is not installed).
GNOME 43 will arrive in September
Although there are more novelties, what is most striking are the quick settings of GNOME 43. In the header screenshot we see the current one on the left and the future one on the right. We can say little about the current one, it is what we have been seeing for a long time and it has a design that is normal on the desktop. However, the one on the right is very different. The one in GNOME 43 also allows us to access the Internet connection, the power profile, and the volume slider, but toggles for night color and light/dark mode have also been added. We can also access the configuration and session management, but the buttons have been moved to the top.
As for the design itself, the new one is more like what we see on mobile devices, and it was probably designed with them in mind. Although GNOME hasn't been on mobile for as long as other projects like KDE, it does work to improve things on this type of device, and as proof we have the new Nautilus which is now more responsive.
GNOME 43 will arrive in september, and there is still time for them to introduce more news before the final freeze. Ubuntu and Fedora will include it out of the box, and other distributions will follow. The Rolling Release could receive it the same week of the launch.
