I'm a System76 engineer / Pop!_OS maintainer. I've been a Linux user since 2007; and Rust since 2015. I'm currently working on COSMIC-related projects.

You have to type the key sym name into the input field. It is not a raw shortcut editor yet.

You are already on the LTS version if you've installed the COSMIC Alpha 6 ISO, or did a release upgrade.

rm'd a project that was months in the making a few days before launch... What to do if you kill the wrong file without a backup

It's really easy to configure a self-hosted forgejo instance. Even if you rm your local work, you can clone it from your server. Be that hosted on the same system over localhost, or on another system in your network.

COSMIC Alpha 6: Big Leaps Forward

3D acceleration is required with cosmic-comp right now. I'm not sure if software rendering will be ready or not for the first release, but it is on the issue board.

Cosmic Desktop - A Review of the Latest Alpha 6

See the Ubuntu Summit 2024 talk: https://www.youtube.com/watch?v=bwrBKccfYws

It’s not resources, in fact, this Alpha performs pretty poorly on its own vs Gnome

I haven't seen any benchmark where GNOME was more performant than COSMIC. Despite alpha status, it is already much more responsive than GNOME.

GNOME uses a single thread to render all displays in a multi-display configuration. This is often so slow that they need to rely on double or even triple buffering when the frame rate lags behind the display's refresh rate. Meanwhile in COSMIC, thanks to the thread safety features of Rust, it was easy to implement thread-per-display multi-threaded rendering. This means that each display is rendered and composited independently on their own respective threads.

GNOME's compositor also has an entire JavaScript runtime bundled inside of it, which it uses for drawing interfaces and handling application logic for those interfaces. All within the same process as the compositor, slowing down its event loop. COSMIC instead keeps the compositor process very lean, with all desktop interfaces running in their own isolated processes outside of the compositor via wayland's layer-shell protocol.

COSMIC Alpha 6: Big Leaps Forward

Doesn't matter. New compositor: cosmic-comp. Does not share any code with gnome-shell or mutter.

OpenGL is required, even if by software rendering.

COSMIC Alpha 6: Big Leaps Forward

Virtual machines have always been supported as long as you enable GPU acceleration. GNOME Boxes, virt-manager, and VirtualBox have been tested.

COSMIC Alpha 6: Big Leaps Forward

The alpha began in August of last year, and will continue to be classified as alpha until all features are finished.

System76 Releases COSMIC Alpha 6 Desktop Environment

Give it a try. We are close to being finished. I don't even know why anyone would think this isn't a thing.

Fedora with Rust based COSMIC DE proposed

Alpha 5 is actually releasing next week. I'd also disagree with "very alpha" as most of the beta milestone is finished now. Regardless, I don't understand where the disconnect is. A spin can release at any time. Doesn't matter when COSMIC Epoch 1 releases.

Fedora with Rust based COSMIC DE proposed

That would be completely wrong. See the Fedora Miracle Spin, for example. The project (miracle-wm) is still a work in progress, and yet Fedora already officially offers a Spin for it. What you're describing would only be true if Fedora was switching to COSMIC as the official desktop for Fedora.

Share specific examples of software built from source works better for you than packages or pre-built binaries

That just depends on your use case. I'd imagine you'd only get 5-15% performance difference. Choice of programming language and the quality of the code makes a bigger impact on performance. Case in point, Rust's png library is 1.8x faster than the C libpng system library. Of course, only Rust applications benefit from that, unless the C libpng maintainers decide to adopt Rust's png library as their implementation.

Fedora with Rust based COSMIC DE proposed

There would be no reason to delay anything regardless of it being beta or not. Fedora is always doing rolling release updates of software that lends well to that paradigm, and COSMIC is one of those. It's not like GNOME or KDE where you have to carefully and meticulously manage 100 system libraries used by the whole ecosystem. System dependencies in the COSMIC ecosystem are virtually non-existent. If they really wanted to, they could just wait a few weeks to release the spin. But I don't think there's any reason to.

Pop!_OS 24.04 and new COSMIC desktop hit alpha • The Register

Michael Murphy (S76) @lemmy.world 2y ago

Wayland compositors use IPC over a UNIX socket to communicate with Wayland clients. To increase security and enable sandboxed applet support, COSMIC applets use the security-context protocol for their IPC connection to the compositor. To be an applet, COSMIC applications use the layer-shell protocol to behave as an applet. Neither of which were made for COSMIC. Some other Wayland compositors support these protocols. You can see which compositors support the protocols at the bottom of the wayland.app protocol pages.
