Pop!_OS (Linux)

The COSMIC Desktop recently dropped and whilst I did a first impressions stream I wanted to put together a more coherent review of the desktop so here it is, yes it's an alpha, yes it's buggy, but it has a lot going for it.

I've been waiting until the alpha release to try cosmic, so I haven't paid much attention to instructions for installing it alongside my current pop os 22.04. Now that the alpha is out, I see all instructions pointing to download and install the 24.04 alpha iso. But, that's a big hassle! Is there a way I can try the cosmic alpha along side my current install?

Hey everyone! I've been using the Cosmic DE Alpha since yesterday and have been enjoying it so far! What I've been wondering though - is there any place where I can see all the keyboard shortcuts that are used for the tiler and other features, and maybe even change them/set new ones? No matter if it's some piece of official documentation or a config file. Thanks for your help!

RUST Cosmic Desktop on Pop!_OS made by System 76 is available and ready for testing. The ALPHA release has officially dropped. Let's do an in depth review about the latest updates on this Cosmic Desktop for Linux environment. Open source dev is great!

COSMIC Desktop debuts with insane customization options with Pop!_OS 24.04 LTS!

As the first alpha version of COSMIC Epoch 1, it is incomplete. You’ll most certainly find bugs. Testing and bug reports are welcome and appreciated. New feature requests will be considered for Epoch 2, COSMIC’s second release.

COSMIC Epoch 1 (alpha 1) on the Pop!_OS 24.04 LTS alpha ISO files are available

Whenever I update a package or the system via the Pop! Shop, or downloading a game or updates from Steam, my desktop constantly freezes and hangs. It works perfectly fine otherwise.

I was wondering whether this was common behaviour. It's a bit frustrating because it means I have to pick my moments to update to be when I can go do something else for a while and come back.

If I'm on a Discord call and am doing an update or downloading a game on steam, the freezes mean that my friends can't hear me and I can't hear them.

I've tried Googling it but haven't found anyone with this specific issue yet.

I run a medium-power gaming desktop rig.

Any advice on how to fix or improve this?

Update:

Here are my hardware specs. Sorry for not including them earlier; I was at work when I posted this.

• Motherboard: Gigabyte Technology Co., Ltd. X570S GAMING X
• RAM: 32 GiB
• CPU: AMD® Ryzen 9 5900x 12-core processor × 24
• GPU: NVIDIA GeForce RTX 3070 Ti

Does anyone have experience developing with Unity 3D game engine on Pop!_OS?

I'm thinking of leaving Windows and Pop seems to be the most painless transition, but I want to get into developing for Unity so that's a must for me (I can't use Godot as the SDK I want to use is on Unity only).

Does it work without issues? The Unity site says it works on Ubuntu 18.04, 20.04, 22.04 so not sure if that translates over to Pop. Any advice would be appreciated :)

Worst case, is developing on Unity via Wine an option? I don't know much about Linux so hopefully that's not a dumb question 😅

Many devs dream of one day writing their own operating system. Ideally in their favorite language: Rust. For many of us, this dream remains just that: a dream.

Jeremy Soller from System76, however, didn't just contribute kernel code for Pop!_OS, but also started his own operating system, RedoxOS, which is completely written in Rust. One might get the impression that he likes to tinker with low-level code!

In this episode of Rust in Production, Jeremy talks about his journey. From getting hired as a kernel developer at Denver-based company System76 after looking at the job ad for 1 month and finally applying, to being the maintainer of not one but two operating systems, additional system tools, and the Rust-based Cosmic desktop. We'll talk about why it's hard to write correct C code even for exceptional developers like Jeremy and why Rust is so great for refactoring and sharing code across different levels of abstraction.

I've been able to run all of my other regular games since switching to Pop!_OS, but one is giving me a problem still, Space Engineers.

Tried all of the Protons (and Proton-GE), tried various launch options, read all of the feedback left on protondb website for the game, looking for any other ideas. :)

Hey all, noob here. In the system settings of Pop OS I chose dark mode. At first everything was fine. But something happened. This issue is only happening in the Show Applications area. It is dark mode, but the text is all black instead of switching over to a lighter color like it did before. Makes it tough to read as you can see in the screenshot. I've tried flipping to light mode and then back to dark mode several times of varying length with no success. Any tips to get it back to normal?

Bonus issue: I have uninstalled OpenRGB, but it is still showing up in the app list as you can see in the screenshot. Any way to remove it? If I reinstall OpenRGB, I get a second icon.

I switched to Pop!_OS earlier this year from Manjaro KDE. One feature that KDE had is that you could write a comment on any file by clicking Properties and going to the metadata. I assumed that this wrote the comment into the metadata of every file and that this would translate over to other distributions, but it doesn't appear to be the case.

I found this old thread from 2012 which said that KDE stores it's comments in ~/.kde/share/apps/nepomuk/. If that's still true today, I'm really worried now that all of that comment data I spent hours writing has been deleted along with Manjaro, because I had no idea that the data wasn't store inside the file itself, since it was always listed with the rest of the metadata for every file in it's properties. Is there no hope of me getting these comments back, or is there some way?

Update: Despite what that old thread seemed to imply, it turns out the comments do in fact get stored in metadata. After getting help in the comments, I found the easiest solution was to simply install Dolphin (KDE's file manager) into Pop!_OS, which allowed me to view the comments just as they were when I used KDE. For future readers, some other options that I didn't try that probably also work are:

• Load a Linux distro using KDE into a virtual machine on top of Pop!_OS and view comments that way
• Flash a distro like KDE Neon onto a live USB and view the comments that way
• Use the command getfattr FILENAME -n user.xdg.comment to view the comment data within the Pop! terminal (I didn't get this working, but this was suggested to me)

So just got my computer switched over to Pop! OS.

When I open the Pop Shop, the installers don't give me an option to change the location of the app installs. I have 4 disks, 2 nvmes, 2 hard disks. I would prefer to install some of my apps to the 2nd nvme, which I have mounted to /Apps. Mainly the games I will play, along with Stream and Lutris.

Would I need to install from the terminal with apt or nala? I installed nala because it looks cleaner, but we'll see.

Hi all, I've been running the latest Pop_OS 22.04 LTS, and recently discovered all the new cosmic apps from the upcoming Cosmic DE. They are seriously impressive in both UI/UX and performance, but I got updates to all of the cosmic apps yesterday, and now when i try and launch any of them, they simply hard lock my computer, forcing a hard reboot to recover.

I noticed a few recent reports of similar behavior over on Reddit, but Reddit 'tis a silly place, so I'm posting to Lemmy instead.

Since I cannot copy/paste any errors, i took a picture and hand typed out what happens when i launch cosmic-store from a terminal. It appears to be a json-ish error.

I wanted to build and use cosmic epoch on my void linux system with seatd, but i could not find build and install instructions on the project's README.md. Although it did have installation instructions for PopOs, fedora and arch based distros. If someone has already installed it, can you please tell me if it is possible to install it on void with seatd and how do I install it...

Worth watching

I have written a calculator in Rust and libcosmic, the design is copied from gnome-calculator; I discovered 2 things:

1. I don't like working on UIs.
2. I have no idea how to transform

cosmic::widget::button::Builder

to

cosmic::widget::Button;

this code would be so much cleaner if I could return a button::standard() from a function.

The source code.

I’m not super familiar with the differences between x11 and Wayland, but I’ve been experiencing some screen tearing in games with x11 that I don’t remember experiencing in the past. I’ve heard Wayland is more performant, but does that mean anything when gaming?

I am using an AMD gpu with just out-of-the-box settings. No additional drivers or tinkering.

After updating system76-power yesterday, today charge thresholds aren't working. Running system76-power charge-thresholds gives this:

org.freedesktop.DBus.Error.Failed: Not running System76 firmware with charge threshold support

Anything I can do besides wait for a fix?
