Cosmic Desktop Anyone? Recent Alpha 6

Has anyone played with installing the Cosmic desktop recently? I have been experimenting with an ISO build with the Cosmic desktop and my initial impressions are very good. For an alpha status, it appears to be coming along nicely.

Yeah it could be interesting to check out in the future but I think I stick with KDE.

Hopefully Cosmic will be ready for Pop!_OS 26.04 release. Tbh, I don’t see it coming any sooner, but glad to see it gains shape with every alpha release.

I don’t think I’ll use it, I have no reason to move from Plasma but I’d rather see them take their time and get it right than release too early like Plasma 4.

I followed the Arch Wiki and installed cosmic-session alongside KDE, it nuked my entire desktop and displayed a black screen with tons of random errors.

You’re the one who posted this publicly, and now my desktop is broken.

Luckily I had a good Limine snapshot to quickly revert to, which got my desktop back to normal. That saved me time from having to fix all those crazy errors.

It’s not like it’s his fault and he forced you to try it out, OP is just excited for Cosmic and wanted to share his experience. Not sure why you are blaming OP?

You’re the one who chose to install alpha software, my dude.

He posted the link to the Arch Wiki, which never mentioned that this is an Alpha version.
It’s referred to as an Epoch release, which confused me. But this desktop is officially available in the Pacman repo instead AUR.

@eznix mentioned in his topic title “Cosmic Desktop Anyone? Recent Alpha 6”?

Also if you check the details of the “cosmic-session” package,
https://archlinux.org/packages/?name=cosmic-session, it has “1.0.0.alpha.6-2” in the version and so do the other cosmic group packages.

COSMIC-Epoch is meant to be differentiated with the current stable COSMIC, which is only the set of in-house GNOME extensions for Pop!_OS.
That’s basically it.

As well as mentioning it in the title

Plus I’ve been running Cosmic desktop (well installed and occasionally using it) with Plasma since pre-alpha, it’s never caused any problem with my Plasma session.

Hello,

I installed cosmic when in came to alpha status just to try out. It looks interesting to me - and I think about using it, when status is at least beta or better stable. It seems to be fast.

I observed that cosmic filemanager overwrote the default filemanager setting for my Gnome session (so, I de-installed that again).

@Phodox You can select in GDM which DE you want to start; I usually use Gnome (Wayland) ; sometimes I check out Cosmic or LabWC … or even Gnome (X11). Except from the file manager issue I observed no interference.

Ciao,
Photor

I am truly sorry that you had taken the leap and it caused damage to your installed system. That was not my intention. I was merely interested if anyone else tried this desktop environment. I have been playing with Cosmic in its own ISO (not alongside any other desktop environment).

I did not think it needed to be said, but installing multiple desktop environments is usually not a good practice. I would certainly do that type of thing inside a VM and see how it goes before trying it on metal, especially my daily driver machine.

Glad you got back to a working state. Btw, if you switched over to Limine bootloader, you must be pretty confident in your skills.

@Phodox, Installing 2 DEs on any distro is just asking for trouble. Sometimes things just don’t work as intended. And installing an ALPHA DE alongside Plasma is just a bad idea.

You have no reason to need to apologize, everyone is responsible for their own actions they do with their own system.

The conflict between DEs in mostly in how much they have in common/share. Cosmic doesn’t share anything with any other DE as far as I know, though it would have most in common with GNOME perhaps and I don’t see anything that loads unless you start cosmic_session.
I haven’t seen anything that I would consider a conflict between it and Plasma.

I have no possibility of alpha/beta testing and bug reporting to Cosmic developers.

I’ll install the final release though on Arch on metal and take it for a ride.

I doubt that it will replace my current GNOME setup that I am well-entrenched in using it and enjoying it a lot.

I do however dip my toe in KDE Plasma water and have it installed on its own as well and run it once in a while.

No, the ArchWiki article does not advise this.

What’s with the accusatory tone? Take some responsibility for yourself. You are not a baby.

@joekamprad put together some notes for installing COSMIC on EOS (using the installation customization tools):

There is also a COSMIC ISO available on Garuda Linux if anyone wants to check it out.

I agree the COSMIC alpha is pretty good for what it is! Certainly there is some bugginess, but it is very impressive how quickly they have gotten it into a usable state.
