r/COSMICDE

I'm running Cosmic on CachyOS, and I find it impressive. I'm using an older ASUS ROG laptop with 16 GB of RAM and SSD; everything works perfectly.

Fastfetch shows version 1.0, even though the terminal reports version 1.2. I believe they are on a version beyond 1.0, but nothing directly related to Cosmic shows up via pacman, and I don't want to force it—it's working too well as it is ☺️

I just want to express my appreciation for the work put into the Cosmic DE; after getting tired of KDE and GNOME, it feels really fresh.

Want to talk open source with top Linux developers?

Join System76 founder Carl Richell and his Pop!_OS and COSMIC DE dev team for COSMIC Convergence 2026 in Warsaw the evening of Aug. 1. Chat about open-source computing and be part of the future of the Linux desktop! (And yes, food will be served.)

When I move an application window from one workspace to another, it tiles it vertically (it was horizontal in previous gnome based version). This is really annoying me as when I want to move across multiple workspaces, it takes so many step (also I almost never use vertical tiled applications as it's less practical than having 2 windows side by side horizontally). Can this be somehow changed?

Another thing, is there any way to create a new workspace to the top/left (start), like in the previous version.

Hey everyone,

Earlier this year I made the jump, fully switched to Linux on my personal machine. Coming from macOS there are obviously some adjustments, but one thing that kept nagging at me was the app switcher. On macOS it pops up right in the centre of the screen, so your eyes never have to leave where you're already looking. The default Super+Tab on COSMIC shows your open apps at the top of the screen, and on a larger monitor constantly glancing up there just never felt natural to me.

So I built one.

cosmic-app-switcher is a macOS-style horizontal app switcher for COSMIC desktop. It shows your open windows centred on screen as a floating overlay, hold Super, tab through, release to switch. That's it.

I built this clearly with the help of Claude, which made it genuinely possible for me to tackle the Wayland protocol quickly.

It's fully open-source:

👉 https://github.com/j0rdiun/cosmic-app-switcher

One-line install (no Rust required):

curl -fsSL https://raw.githubusercontent.com/j0rdiun/cosmic-app-switcher/main/install.sh | bash

If anyone's wants to give it a go, I'd genuinely love the feedback. Bug reports, ideas, PRs all welcome.

So, for the first time, while using Cosmic on my laptop, I decided to fire up a Citrix Workspace session to get some real work done. With the Cosmic DE, the resolution of the session was off. All appeared very tiny, and sadly, I am unable to make adjustments to the remote session's display settings.

I switched to Gnome and the remote session has perfect resolution.

With Cosmic and Gnome being so close in usability for me, the one that delivers when I need to get some work done on it will win as my default. I'll keep COSMIC installed and have a look now and again.

I don't know what is the cause for the Citrix Workspace remote session resolution not adjusting to match my desktop. I've tried everything but think it's just Cosmic since I try nothing on Gnome. It simply works.

So it would seem that for straightforward activity in Cosmic, it's working great, but I know that running a Citrix Workspace remote desktop session is on the fringe.

Hello,

I'm wondering if there is a way to make it so that if there is only one window in tiling mode, the window is automatically maximized or the gaps are removed?

It would be so much nicer! ^^

I would love for there to be a paid app store for flatpak apps and for flathub to finalize the infrastructure to support this I know this is legally challenging but also I really want to support developers and allow them to work full time in Linux and on software, and therefore the entire quality will rise, also I like to support developers if they are happy to work full time in Linux development in a Way that supports them to develop full time on kde or cosmic or gnome

On Cosmic you can feel the sophistication with the modularity and sophisticated architecture and design and incredibly intuitive UI with libcosmic and context drawer design which looks. Beautiful. The only problem I have now is only the exception of a some bugs like os error in cosmic files and others that I can see are already being worked on in GitHub. To develop something this great and performant in such a short space of time is incredible, I would love to support them in someway I am not in USA so it's hard to buy their hardware which I really want to do. if they do cosmic sync as a service I will definitely purchase this and its a way i can support system76. It would also be great after epoch 3 to have a Cosmic browser based on servo that maybe also comes with cosmic account and syncs your cosmic browser with cosmic sync. I wish to support in anyway. and will be looking forward to getting all my tech stuff from now where is possible from system76.

Took a a little bit of work but got it built and installed on a Debian 13 VM, most everything is working. Hopefully it gets added to the Debian repos eventually, very nice DE, and would use it over Gnome or KDE any day.

Hello,

I am running Pop 24.04 with Cosmic DE, fully updated. Something that I have not yet been able to do is finding a color picker tool/app that works. Ive tried the gnome color picker, the cosmic color picker and many other options. Everytime it is the same, I cannot make the "droplet thing" appear to pick a color from what is displayed on my screen, and no matter what I click, I still cannot pick a color.

I have tried both system and flatpak versions of different apps.

Does anyone know why? Is there any app that works?

I am running a desktop with a core i7-6700 and a dedicatex AMD GPU.

Thanks!

Has anyone here successfully changed their cursor theme on COSMIC? I've seen some guides on the internet, but it never really turns out well.

Has anyone started having issues with one of their displays will randomly turn gray? When I move my mouse over parts of the GUI on the other monitor, the gray monitor will start flickering back normal and gray. Sometimes it also crashes forcing me to reboot. It didn't used to do this, but I'm not sure when it started or where to look for logs on what might be causing this bug?
