Some of us are noobs

[authenticastrology]

Some of us...well okay... at least myself are not fully adept with flakes and it is like rocket science to us. But, we want to install Cosmic anyway. Would love a step-by-step guide. Know you may not have the time. But if anyone else does, it would be excellent. Or a video. But knowing whether to add this to the default flake, and how...Or whether to create a new one...would be excellent.

Sorry if this is the wrong spot for this. But nowhere else to comment.

@authenticastrology The README generally demonstrates what you'd need to add to your flake to add nixos-cosmic as an input to your flake, as well as how to utilize it into your system configuration.

For example:

to the default flake, and how...Or whether to create a new one...

is a bit confusing, or leads me to wonder if you have some confusion?

For example, I have a single flake that encompasses:

• my laptop nixos config (which utilizes the nixos-cosmic nixos module)
• my server nixos config
• devshells for various "things"
• various packages that I have pinned to tip versions

That singular flake is where I added nixos-cosmic as an input, and then in one of my system configurations, I pull in the nixos module, from that flake input.

@authenticastrology, were you able to get sorted to get up and running?

[authenticastrology]

No, not yet. But, thank you.

Can you tell where you're stuck? Or provide your dotfiles?

What always helped me a lot in the beginning is to see how other people have implemented it, so here are my dotfiles if you want to take a look at them.

i just got it working yesterday. I recommend you spend some time reading the the wiki on flakes + get help from claude.ai and phind.com or whatever LLM you like for troubleshooting.

one thing missing in the readme (I think?) is that you should do sudo nixos-rebuild test --flake . and not just nixos rebuild test before adding the cosmic enable in your configuration.nix.
Then rebuid with sudo nixos-rebuild switch --flake .

Also make sure you did not add any nixpkgs input in your flakes inputs beside the cosmic one to benefit from cachix.
I’m quite clueless about nixos this took me a couple of hours. My config had some cleanup to do. If you start from a vanilla install, it should be easier.

[authenticastrology]

I am almost embarrassed to ask. I am still just barely grasping flakes. I would be really grateful if someone has a pre-made template just for Cosmic with nothing else on it and if they would tell me step for step how to set it up, where to put it no wise cracks huh...lol), which command lines to run. It's going to take me months to grasp flakes due to timeload. I switched to Cosmic as my main driver directly from Pop. But would really love to use it with NixOS. Need some help. Thanks to everyone so much.

I got it all figured out! Yea!!!!!!!.

Question though....I know it's in Alpha. But is anyone else having issues with lag when things open?

I have used the Pop OS version too and it seems a bit snappier.. Not sure if it is a NixOS issue or not.

If my dGPU is not active, launching windows takes longer than it feels it should. It fires up the dGPU for animations, then animates opening the new window. For me, it's quite noticeably slow, but I'm also behind on updates, so hoping it improves...

[tilupe]

Hey I just started with NixOS and wanted to install cosmic too. When running a nixos-rebuild, it always gets stuck at this phase

It just compiles there for a long time and at some point it the terminal crashes or after a while I get logged out and everything is cleared. Anybody an idea what I can do to change that?

[hanckmann]

@tilupe I guess you are being bitten by this issue as well: #495

Unfortunattly it produces the following error for me:

Ok, it seems the problem was that flake was initialized in my home directory and not in /etc/nixos, but everything is compiled locally for me, still some progress I guess :)

[Elias-Graf]

@artsiomkaltovich no, the issue isn't where the flake flake was initialized, but that you forgot to move a file, in this case "configuration.nix" into the repository. OR, something I've run into a couple of times myself, flakes only consider files, that have been added to the git index. That's why my rebuild command is this:

nix fmt && git add . && sudo nixos-rebuild switch --flake .#<NAME_OF_HOST>

and I just reverse search my history for rebuild.
