I don’t think anyone has done this yet.

You can either return cosmic::Element<Message>, impl Into<cosmic::Element<Message>>, or cosmic::widget::Button<Message> with your functions.

Every widget can .into() or .apply(Element::from) into a cosmic::Element.

I’d recommend using the Grid widget so that your buttons can scale with the window.

cosmic::widget::grid()
    .push(widget1())
    .push(widget2())
    .push(widget3())
    .insert_row()
    .push(widget4())
    .push(widget5())
    .push(widget6())
    .row_spacing(12)
    .column_spacing(12)
    .justify_content(JustifyContent::Stretch)
    .width(Length::Fill)
    .height(Length::Fill)
    .into()

This may be fixed now, but at the same time, I’d wait a day before updating cosmic-comp because xwayland’s currently broken while we need to update xwayland to the latest version for explicit sync support.

That’s very strange. Did you update today?

You can send an email to info@system76.com

The design is finished for Alpha 1, but there is likely to be future design work once designs are revisited for alpha 2 or the beta.

That’s up to you. If you need it, you can always reinstall it.

I’d recommend everyone to try out cosmic-store (with cosmic-icons) when they get a chance. Whether you use COSMIC or not, it’s fully functional with any desktop environment. It’s packaged by default in Pop!_OS 22.04, available in Fedora 40 via ryanabx/cosmic-epoch, and the AUR.

Every application launches within 0.2 seconds for me. Maybe you need to play around with env WGPU_POWER_PREF=high

There will be configuration options eventually

This video is very outdated by 3 months. Although I’m not sure if COSMIC has been on The Linux Experiment since then.

Not yet, but PRs welcome if anyone has experience with theming Qt.

24.04 releases somewhere near end of summer. Super + 1-9 is already bound to workspaces in COSMIC.

Pop!_OS 22.04 uses GNOME with a lot of custom extensions and patches. Pop!_OS 24.04 will switch to COSMIC.

GNOME Shell extensions are JavaScript monkey patches that get injected directly into the gnome-shell process, which is running inside a JavaScript runtime. So they have no effect outside of GNOME Shell.

COSMIC panels are already configurable, so there’s no need for a third party panel applet to have dock applets embedded in the panel. You can configure the panel and dock to any layout. Be that a GNOME layout, Unity layout, Mac OS layout, Windows layout, etc.

It would be redundant to rebrand Pop!_OS to COSMIC OS. The cosmos was created by a Pop!

It is a desktop environment, which is the entire graphical user interface of the OS, and all of its bundled applications. It is also a platform which developers can build COSMIC applets and applications with. Applications being desktop applications, and applets being the shell components. Shell components are small interface elements such as the panel, dock, panel buttons, on-screen displays, launcher, etc.

It will take its place alongside the two giants in this space: KDE and GNOME. KDE being a desktop environment whose applets and applications are written in C++/JavaScript using Qt/QML as its GUI library. GNOME being and desktop environment whose applets are written in JavaScript with the GNOME Shell Toolkit; and its applications are written primarily in C with GTK as its GUI library.

COSMIC is instead built from the ground up entirely in Rust from top to bottom. Every applet and application is written in Rust, and the same libcosmic GUI library is used for developing both of them. Rust is a statically typed programming language which has dethroned C/C++ in recent years, and has been the most loved programming language on StackOverflow for the last eight years. We aim to make COSMIC the preferred platform for developing applications in Rust, with a GUI toolkit that’s easier to develop than the alternatives.

It is possible. This is the beginning of our theme integration support.

1. Desktop and Panel > Dock > Position on screen > Left
2. Dock > Configure dock applets. > Drag Cosmic Dock App List to Start Segment
3. Dock > Extend dock to screen edges

If the dock takes dominance of the left side, move it back to the bottom to give the panel dominance, and then move the dock back to the left.

Yes, Ubuntu.

I’m referring to the COSMIC App Store. Not the Pop Shop.

It’s not possible to measure yet. Too many moving parts and a lot of optimizations aren’t finished yet.
