Not ready to release yet

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.

Niri is also based on the smithay library we use for COSMIC, so there’s some collaborative work between COSMIC and Niri on Smithay.

applets live in their own process and communicate via Wayland protocols (behind a COSMIC API)

Even better. A COSMIC API was not necessary since Wayland protocols already exist for this (layer-shell and security-context).

It already is available. See the links on the COSMIC webpage: https://system76.com/cosmic

No, we won’t be spending any development time on porting all of the patches in 22.04 to 24.04. GNOME is done.

You should stop using Linux then. The Linux kernel, along with many open source software, is developed and sponsored by for-profit organizations. Either directly or indirectly. Without them, open source wouldn’t be able to thrive.

It is required to install system updates before using the alpha.

They’ll be available after COSMIC releases.

No

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?

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
