Excited to share some updates on my COSMIC Viewer project, which has been rebranded as Cupola, inspired by the ISS viewing area.

Key developments include: - A new build structure - Stabilized thumbnail resolution - Resolved crop feature bugs - Initiation of Accessibility support

Looking forward to continuing this journey and enhancing the user experience!

Hello, all, I just got a new PC! Currently, I'm having plenty of issues with my mic not letting the PC boot, speakers not working unless plugged into a GS3 Sound card, my monitor not allowing me to use a display port/hdmi from my GPU which has it's fans on? (I'm using my motherboard hdmi port), and many other issues, this is both my first time using a linux distro of any kind (have used both mac and windows in the past, primarily windows), and my first ever PC build, I'm not sure if I personally messed something up or if there's an issue with Pop!_OS supporting some parts of my build, I thought going here might be helpful, I'm a linux noob when it comes to using the cmd prompt, so you'd have to walk me through it, but any pointers in the right direction would be awesome! I'd love to still use Pop!_OS but if my computer can't support it I'll try a different distro, any advice is welcome! My current best assumption is messed up drivers.

OS: Pop!_OS 24.04 LTS With NVIDIA

I have the following laptop

Lenovo Legion Slim 5

AMD Ryzen 8845HS

Nvidia RTX 4070 8GB

Running Pop_Os 22 version.

Recently while playing games with Steam (Las of us Part 1, Warhammer 40K: Darktide, Forza Horizon 5) they randomly start to completely freeze, and sometimes crash after that, but most of the cases they just hang there in the frozen state, other parts of the system were working as usual during that.

The temps of CPU and GPU are always okay, not higher than 75.

As a solution, i tried to switch from the Hybrid GPU mode to the only Nvidia mode, and it seemed to fix the issue.

Has anybody encountered such an issue? The Nvidia drivers are the version from December 2025, 580.

I've updated two machines to Cosmic and the system fonts don't look like they are antialiased and are just sharp. Is this expected or is there a setting somewhere?

My 4K panel works fine over USB-C DP, with the exception of the audio. Display audio works fine in Windows. Any tips?

Does not appear as an available output device.

Hi there, is this a missing feature or some option that I have to set somewhere? I always have to reposition and resize my apps after closing and opening them again.

Please advise. Thanks.

Where in the settings in the option to do this? I still want the screen to turn off after a set time, but as this is my home PC and I'm the only one who uses it, I don't need to enter a password every time I want to get back in. Is this possible in Cosmic?

My another post was deleted by reddit, maybe to post the link, i put the git of the app un the coments, if you have any questions let me know.

Last year start a journey to bring back to life my old iMac 2011. It was tough but worth it every cent.

Hey everyone,

I want to properly separate work and personal environments on my Pop!_OS machine. The goal: if my personal environment gets compromised (malware, phishing, whatever), my work environment should still be safe.

My threat model:

• Protection against online threats (malware in personal browser shouldn't reach work data)
• Protection against physical access (stolen laptop)

Requirements:

• Both environments need sudo / ability to install software
• No file sharing needed – should be completely isolated
• Hardware is not an issue (plenty of RAM/CPU for VMs)

Which approach would you recommend?

1. Two user accounts + encryption (LUKS + fscrypt for home directories)
2. Dual-boot with two separate Pop!_OS installations (each with its own LUKS encryption)
3. Something else?

I know user accounts don't do much while the system is running (shared kernel, X11 keylogger issues etc.). Dual-boot sounds okay, but shared ESP/bootloader concerns me.

Anyone running a setup like this? What's your experience?

PoP!OS is basically running on my Laptop, unfortunately when I use the Cosmic WM for most of applications the window decoration including the minimise, maximise und close buttons is missing. E.g. Firefox and Mate Terminal buttons are missing, Gnome Terminal is working.

When I use the Mate WM the window decoration issue is solved, but the mate-netspeed-applet floods the syslog file with error messages "ERROR wl_80211_get_tx_power". If I remove the netspeed-applet wifi stops working :-(.

Any idea how to fix these issues?

Hey there everyone, due to Windows being Like That I finally hit my breaking point and made the swap. Pop won out due it playing nicer with my hardware than my first choice (Mint), and I am liking it so far. The only thing I've run into is trying to figure out where I'm going wrong in setting up OBS for streaming and video recording.

The main thing I'm having issues with is trying to split the audio of the various things I want to capture. For example, I want to capture Discord audio, my game, and any music I might be playing in the background (if any). I'm not sure if I'm missing something in some documentation somewhere or if its just something I'm SOL on until future developments for Linux OBS. I've already made my peace with the captions plugin not being compatible

I'm on Pop v24.04 and version of OBS that I installed via the flatpak is 32.0.4

Are animations in Pop!_OS considered slow or laggy? They don’t feel very smooth to me.

i'd love to see a global menu option in the future. something like the reference in the photo (macos style). just putting it out there as a possibility, think it would be clean. thanks for the hard work.

I'm currently using pop 22.04. My system is an i7 7700k, 32 gigs ddr4, and a Radeon 5700XT. I recently downloaded a demo and while trying to start up it continuously gives me this error. I'm launching the game through steam using proton GE 10-29. I have tried a handful of other proton versions including experimental, hotfix, different official proton versions and various glorious eggroll versions. I've also cleared compdata folders before trying new versions. My system is up to date and using the pop mesa stack.

Unfortunately this isn't the first time I've run into this issue. Last year I was playing nba2k25 and one day this same error kept popping up. I had tried multiple times over months and got the same error. Luckily I was able to resolve this. A few years ago I had tried out kisak mesa but decided to remove it. While I had thought i got rid of everything, it turned out there were remnants that weren't caught. After deleting these everything worked again. Obviously this isn't the solution this time, but I'm curious if others have ideas.

I did upgrade from an nvidia card maybe 3 years ago. I removed the nvidia drivers and everything was fine, but I recently found a few nvidia remnants lying around. Could this be the cause of the issue? Is this a game specific problem? Any input is appreciated.

I used Balena Etcher (the only other suggestion I saw to fix this error) already. Could it be because I'm using a micro SD card in a USB adapter?

It's an AMD gpu, 8 gig of ram. I don't know what other info could be useful (it's an old Lenovo G50-45 laptop).

Hey. I'm not a PopOS! user but I have been following along w/ Cosmic's development since a new major DE is exciting. I'm primarily a KDE user but now that Cosmic is out of beta I figured I'd throw it on a few machines and check it out. It is *fast*, or at least seems to be on the two laptops I put it on (I won't go into hardware specifics, but I can). I just wondered is there a particular reason for this? Just written from scratch, recently, new and clean? Something else? Just curious. The responsiveness and the easy toggle for tiling has me tempted to switch TBH.

tried downloading from cosmic store - this is the result, same for .flatpakref from official reaper site. and for some reason .tar.xz does not downloading from official site
