42 inconsistent GNOME themes affect Although themes can still be installed, all GNOME wallpapers support dark style preference

The new look for GNOME 42 isn’t just an easy-to-change theme. Like many modern desktop computers, GNOME uses a lot of web technologies. GNOME 42 will be the default desktop for Fedora 36, ​​although Fedora does not have LTS versions. A new version is released twice a year, so Fedora 37 will almost certainly get GNOME 43. If Red Hat community members who use GNOME don’t like the 42 look, they won’t have long to support it, but Ubuntu users will have to, or Moving to a short-term support channel, which may not be applicable to everyone.

GNOME, short for GNU Network Object Model Environment, is a free, easy-to-use desktop environment that aims to make the use of the GNU operating system accessible to as many people as possible; This interface is currently common on GNU/Linux systems and also works on most UNIX-like systems. GNOME with KDE is the main free and generic alternative to the interfaces of the most popular operating systems (ie Windows and Mac OS X).

GNOME is developed by the GNOME Project in which volunteers participate or are paid by companies outside the project. Most of the work was provided by professional contributors, especially those who work for Red Hat. GNOME is the desktop environment used by default in many Linux distributions, such as Ubuntu and Fedora. Its software is usually released under the GNU GPL and its libraries are released under the GNU LGPL.

The team responsible for its development announced On March 24th, version 42 . is available. However, her new appearance is already causing cries of displeasure. This release is significant because it will soon be the default desktop for the next Ubuntu Long Term Support (LTS) release. This means that many people will see GNOME 42 every day until 2024.

GNOME themes were described using CSS. Since GNOME 3, the default GNOME theme was Adwaita, it was easy to install new themes, and there were plenty of options. Today, that has changed. A component of GNOME 40 and later is version 4 of the Gtk Toolkit. With Gtk 4 came a new library called libadwaita. It integrates the separate Adwaita theme once and effectively enforces it on all apps using Gtk 4. The goal is to help developers comply with the new GNOME interface guidelines.

A new global dark UI style preference has arrived in GNOME for version 42. This can be used to instruct apps to use a dark UI style instead of light. The new setting is found in the new Appearance panel of the Settings app and is followed by most GNOME apps.

The screenshot above shows the difference. At the top left is a new text editing app, with sharply rounded window corners and flat, borderless control buttons. In the upper right, we find the old GEdit, and below, the Files window. The design is a mix: the top corners of GEdit are less rounded and the bottom corners are square. Files have the slightly rounded corners of GEdit, but the CSD pseudo-title bar controls have limitations, unlike the more modern text editor.

All GNOME wallpapers support dark style preference, so switching to dark style also switches to a darker background style. Under the hood, a new dark style allows apps to provide their own style settings independent of system style preferences. This allows you to switch individual apps to dark or light, if you prefer to use them that way.

However, it is important to clarify that dark mode is not new for Ubuntu users since the Yaru theme for the distribution has already introduced one.

With Gnome 42, themes are still possible to install. But it will only affect applications that use Gtk 3. The small problem with version 42 is that some components of the GNOME desktop itself still use Gtk 3, notably the file program (it’s still called Nautilus internally). This means that the file manager does not match the new file look and feeland if the user tries to customize it, the delay will only get worse.
