I Tried System76’s New Rust-based COSMIC Desktop!
|
||||
======
|
||||
|
||||
If you didn’t know already, System76 developers have been [working on a new Desktop Environment][1] (dubbed COSMIC) written in [Rust][2]: a memory-safe and superfast programming language.
|
||||
|
||||
Creating a desktop environment from scratch is no small feat. That involves creating everything from the compositor, panel, window manager to the APIs for your desktop environment and other back-end tasks.
|
||||
|
||||
It is not an easy task, and maintaining it is another story.
|
||||
|
||||
And, it looks like System76 has already started working on it!
|
||||
|
||||
On GitHub, you will notice there is already a repository called [cosmic][3], but it is mainly in JavaScript (the language used to create GNOME shell extensions). This is the cosmic shell extension repository, which is what Pop!_OS ships with now.
|
||||
|
||||
There are a couple of newer repositories on their GitHub profile, which happen to be the elements of their upcoming Rust-based COSMIC Desktop.
|
||||
|
||||
So, it is time to build, test, and get an early look!
|
||||
|
||||
**Note:** _To clarify, the current GNOME-based desktop environment on Pop!_OS is COSMIC. This article discusses the Rust-based COSMIC desktop environment, built from scratch_, _meant to replace the current offering._
|
||||
|
||||
### Rust-based COSMIC Desktop Experience
|
||||
|
||||
The three repositories intended to be a part of the COSMIC desktop environment as a whole are
|
||||
|
||||
* [Settings app][4]
|
||||
* [Top panel][5] (currently for X11 systems)
|
||||
* [Compositor][6] (appears to have support for native wayland, xwayland and X11 systems)
|
||||
|
||||
|
||||
|
||||
#### COSMIC Settings
|
||||
|
||||
![][7]
|
||||
|
||||
**Note:** This is a half-baked early preview to get an idea. The user interface can be fundamentally different as the development continues. So, hold your thoughts!
|
||||
|
||||
This is the settings app for Pop!_OS’s new COSMIC Desktop. It is currently WIP and not ready for use, although if you want to run it and play around with the GUI, feel free!
|
||||
|
||||
So, how does it look different from the current COSMIC experience?
|
||||
|
||||
![Rust-based COSMIC Settings vs. GNOME-based COSMIC][8]
|
||||
|
||||
When writing this, the GUI does not seem to be connected to any back-end APIs. Enabling and disabling “Enable top-left hot corner for Workspaces” toggle does not make a difference, nor does any other toggles, except for the information shown by the ‘About’ section of the Settings app.
|
||||
|
||||
Looking closer at the screenshot, the placements are messy but expected from an early preview (or prototype).
|
||||
|
||||
It looks like they are approaching everything with rounded corners and a cleaner look to it.
|
||||
|
||||
The toggle animation feels quick, smooth and snappy (even inside a virtual machine, cannot wait to try it on bare metal). Considering it’s not even functional, let’s forget about the performance.
|
||||
|
||||
![][9]
|
||||
|
||||
Personally, not a fan of the rounded corner look they are going with. GNOME’s implementation of rounded corners seems perfect to me. But, it should be interesting to see how it turns out.
|
||||
|
||||
#### Top Panel
|
||||
|
||||
As part of the COSMIC desktop environment, the top panel is also being implemented using Rust language.
|
||||
|
||||
As for the appearance of this top panel, I am not exactly sure how to test it without being unfair to it. Launching it from GNOME opens it behind the top bar that GNOME has. So I thought of opening it in a separate window manager (tried only with [bspwm][10] and [i3-wm][11] so far), but that resulted in some quirky behavior like the panel taking full vertical space like a normal GUI software.
|
||||
|
||||
#### COSMIC Compositor
|
||||
|
||||
The compositor for COSMIC desktop environment compiled successfully but would not launch when used with bspwm or i3-wm. I tried launching it in window managers because GNOME does not allow changing compositors.
|
||||
|
||||
This is due to the mess of video drivers in a virtual machine using VirtualBox and the fact that the COSMIC compositor is not ready.
|
||||
|
||||
But, there’s more!
|
||||
|
||||
Developer **Eduardo Flores** also tried the new COSMIC Desktop, sharing some screenshots of the app launcher and the dock in his [blog post][12].
|
||||
|
||||

|
||||
|
||||
The application launcher looks similar, but built using GTK. Similarly, you can also expect a similar-looking application library, introduced with [Pop!_OS 21.10][14], and the good-old dock.
|
||||

|
||||
|
||||
### Concluding Thoughts
|
||||
|
||||
Sure, it is too early to tell where the development is heading.
|
||||
|
||||
It should take a while to expect a beta release for a full-fledged Rust-based COSMIC Desktop experience.
|
||||
|
||||
But, from what we’ve seen here, I am excited!
