As its first alpha release is closing in, we have another monthly update about COSMIC, System76’s new Linux desktop environment written in Rust. This month, they’ve further polished and shored up their application store, imaginatively named COSMIC App Store, and it’s supposedly incredibly fast – something I can’t say for its GNOME and KDE counterparts, which tend to be so slow I’ve always just defaulted to updating through the command line, mostly.

The file manager now has support for GVfs (GNOME Virtual file system) for making external storage like USB drives work properly, and Greeter login screen, Edit text editor, drag and drop, and copy/paste have been improved in various ways as well. Theming has seen a lot of work this month, with support for icon themes added to the App Library, fixed applet sizes, and more tweaks, while light themes have been disabled for now to fix a number of issues with colour selection being too dark.

There’s also display mirroring now, which even works when the individual displays have different resolutions, orientations, and refresh rates. Pop!_OS is now also being built for ARM64, which makes sense because System76 is now also selling ARM servers. There’s also a bunch of work being done by the community as the alpha release nears.

COSMIC Desktop Environment (DE) is a new project by System76, the company behind the popular Linux distribution Pop!_OS. In this tutorial, we will give you an overview about COSMIC DE and its features, and then we will walk you through the steps to install COSMIC Desktop Environment in the latest Fedora 40 Linux system.

A very easy way to try out the current pre-alpha state of COSMIC. I’ll definitely be waiting on a more official release later this year, but man, does COSMIC ever seem way more polished and complete than it has any right to be at this point in time.

COSMIC, System76’s Rust-based desktop that’s going to replace GNOME in Pop!_OS, is nearing its alpha release, and the Linux OEM has published another blog post detailing the latest progress it’s made. First and foremost, theming support has been further refined by adding support for theming GTK applications (both GTK3 and 4) and flatpak applications. If the user has enabled global themes, these themes will be applied automatically whenever selecting a theme to apply. Support for custom icon packs has also been added.

COSMIC now also has an application store, much like GNOME Software and KDE’s Discover, which also takes care of updating installed applications. You can now also drag windows from anywhere inside the window by holding down the super key, which is both a nice addition in general as well as a usability feature. The Settings application has also seen work, and gets a new keyboard settings panel, as well as various other smaller additions. COSMIC also now implements on-screen display toasts for things like changing volume and brightness, and plugging in power.

System76 isn’t the only one working on COSMIC – community members have implemented things like window snapping, touchpad gestures, thumbnail previews in the dock, and more. The community is also working on things like an emoi picker, and a fan control graphical user interface.

There’s a lot more in the blog post, so be sure to give it a read. I’m genuinely excited for COSMIC to hit the shelves, because I’m dying to try it out.

LXQt, the lightweight Qt desktop environment, has released a major new version, which brings with it a whole slew of very important changes and upgrades, with two main focal point.

First and foremost, the desktop environment is now using Qt 6 across the board, meaning the transition from Qt 5 to Qt 6 is now complete. To support themes and the LXQt File Dialog for Qt5-based apps you can install libqtxdg-3.12.0, lxqt-qtplugin-1.4.1, and libfm-qt-1.4.0 alongside the new Qt 6 variants for backwards compatibility. One exception here is QTerminal, whose Qt 6 port ran into some issues, so a separate Qt 6 release will come later.

The second major upgrade that’s still in progress is support for Wayland. LXQt 2.0.0 brings Wayland support for PCManFM-Qt, LXQt Runner, and LXQt Desktop Notifications, and for LXQt 2.1.0 they plan to make everything else available under Wayland as well. This means that more popular desktop environment like Cinnamon and Xfce are starting to feel a little out of step when it comes to Wayland.

One of the major user-facing new features is a new default menu for the panel which supports favourites, a new and improved search feature, and more.
