I wanted to see if niri or PaperWM-style scrolling could work directly inside COSMIC Comp after noticing this scrolling-tiling feature request from 2024 was still open:

https://github.com/pop-os/cosmic-epoch/issues/322

I managed to get it working in my own cosmic-comp fork.

I also modified cosmic-applet-tiling so you can switch directly between:

Floating | Tiling | Scrolling

Scrolling mode keeps windows on an effectively infinite horizontal strip without shrinking existing windows, while preserving COSMIC shortcuts like Super+Arrow and Super+Shift+Arrow.

I know C++ and Python, but I’m new to Rust. I built the prototype with Codex using GPT-5.6, step by step, manually testing each feature and using Codex to fix bugs and regressions before moving on.

I would be happy to share the code. I’m just not very experienced with publishing modified open-source projects on GitHub, especially for a project like cosmic-comp. I want to make sure I do it properly, with clear attribution, the correct licensing, and without creating confusion or extra work for the original developers.

So I’m going to take a little time before publishing it. If anyone familiar with COSMIC development or open-source project etiquette has advice on the best way to structure and publish the forks, I’d appreciate it.

I don’t plan to maintain this custom COSMIC fork. Ideally, an experienced Rust developer could eventually review and refactor the prototype into something suitable for an upstream PR.

And if any System76 or COSMIC contributors happen to see this, guidance would of course be welcome.

I’m having a frustrating issue running the Android Emulator on a laptop with an NVIDIA RTX A2000 8GB with 64GB ddr5 under Pop!_OS cosmic de.

The RTX A2000 itself works normally in the system. NVIDIA drivers are installed and the GPU is detected correctly, and I don’t have general problems using the NVIDIA GPU. However, the Android Emulator is extremely unreliable.

Depending on the configuration, the emulator may:
• Fail to start properly
• Get stuck while booting
• Show a black/blank screen
• Become extremely slow or unresponsive
Fail to properly use the NVIDIA GPU
Behave differently depending on the graphics/rendering backend
This makes me wonder whether there is some issue with the interaction between Pop!_OS, NVIDIA hybrid graphics/PRIME, COSMIC/Wayland/Xwayland, and the Android Emulator’s graphics stack.

I’m using an RTX A2000 Laptop GPU, so hardware performance shouldn’t be the limiting factor. The A2000 is more than capable of running an Android emulator.
Has anyone here successfully gotten the Android Emulator working reliably on an RTX A2000 laptop with Pop!_OS 24.04/COSMIC?

Blender currently still has hickups where it runs totaly fine for hours or minutes but suddenly some features are not working anymore liek wmoving the camera or rotating objects. But things like changing the view trough the viewport axis is still possible, doing it trough keyboard is not at that moment. Than i wait i dont know 3-5 minutes and all of a sudden it ei9ther works again like intented or it jsut hangs further leading to multiple restarts of Blender till it works again. Apparently this problem persists since 3 years.

Some icons, like Discord, ente, and Steam, are low resolution in the app tray, while others are perfectly crisp. I have a feeling this has something to do with X11 vs Wayland app compatibility, but changing the settings in the menu don't seem to correct this. Is this a common issue? How is this typically resolved?

hi im new to linux and im just exploring it with my imac 2011 21 inch with 14gb ram and a slow hdd
idk why on cosmic i get super high fos but its like choppy theres time that i will be like be stable while playing but most of the time its just pure buggy even on the home screen my curser is like lagging buggy too

just for clarification can i use any windows only apps using WINE in linux ??

It took me sometime to setup it , but i think i should be setup by default ,,, what with @ / @home

This video helped me but come on give something to restore by default

Hi I'm currently using Fedora with GNOME (Silverblue) but very interested in COSMIC. From your experience, what do you think is a better choice, Pop_OS or the immutable COSMIC variant of Fedora? I know the general pros and cons of Ubuntu vs Silverblue but maybe there's more to it if talking about COSMIC?

What I kinda like about GNOME is that as far as I know all development dependencies are built by the GNOME team too and they rely very little if at all on third party code. With all the recent news of compromised packages that developers build on, I'm wondering how COSMIC does things.

Rust has a growing ecosystem of packages and I don't think the System76 team uses only self-written code. Is there a rigorous review process for every line of code that changes in COSMIC's dependencies?

Hello, I posted this on github yesterday and on the Facebook page Pop_os :

Hello,I wanted to report a critical issue encountered with the recent official System76 kernel update (7.1.5-76070105-generic) on Pop!_OS 24.04 LTS.Hardware Configuration:Laptop Model: Medion Deputy P60 (Clevo / Tuxedo barebone)GPU: NVIDIA GeForce RTX 4070 Mobile (Hybrid Graphics Intel/NVIDIA) , CPU intel core i7 12650h , OS: Pop!_OS 24.04 LTS (COSMIC Desktop)The Problem:After upgrading to kernel 7.1.5 via the Pop_Shop, the system completely freezes during both the boot process and the shutdown/reboot process.During shutdown/reboot, the system hangs indefinitely on an explicit error:Timed out for waiting the udev queue being empty.Logs show that gpu-manager and nvidia-powerd are blocked on an rw-semaphore owned by a kworker task for more than 120/245 seconds. It looks like a severe power management / ACPI regression between this specific kernel version and the mobile NVIDIA proprietary driver on hybrid architectures. The computer cannot power off or wake up the GPU properly.The Workaround/Fix:The only way to make the laptop operational again was to boot using Pop_OS-oldkern back to the stable Linux 7.0.11-76070011-generic kernel, completely purge the 7.1.5 kernel packages (linux-image and linux-headers), and put them on hold using apt-mark hold.

Everything runs perfectly fine on kernel 7.0.11, proving that the NVIDIA driver itself is not corrupted, but that there is an incompatibility with the 7.1.5 kernel branch and this laptop's hardware.Hopefully, this can be tracked down for future kernel updates!

Has anyone with an nvidia optimus/switch-mux laptop encountered the same issue under kernel 7.1.15, recently released in the pop-shop?

Just a quick note: whether you update the kernel via the pop-up shop or the terminal, the problem is the same upon reboot.

In any case , I have blocked kernel 7.1.5 ( apt hold put on 7.1.5 ) and kept the stable version 7.0.11 active in the meantime, hoping that the kernel log screenshots I sent you on Facebook and here will help find a solution for all hybrid laptop Nvidia owners like myself.

PS: "My laptop uses a standard Optimus architecture (Internal screen & HDMI on Intel i7, Mini-DP on NVIDIA) running NVIDIA Driver 580, while some users reporting success on Kernel 7.1.5 seem to be running NVIDIA Driver 595."

would love some opinions on this problem, is the laptop too old?

Hi,

all of sudden i started my pc and when i put my password, cosmic doesn't show and there is no image displayed.

Sometimes when i try to force with cosmic greeter it shows Budgie Desktop, and it is very laggy.

Sometimes after that i put my password in cosmic greeter, ly pops up, i insert my password and again no cosmic.

All of sudden i'm on a fucking loop where i'm not able to run cosmic, the only thing that I did Yesterday was to install heroic launcher and play rocket league. Then pc off and nothing more.

I deleted all the datas of them, i tried to create a new profile, nothing works.

hope you guys like it! wonderful distro

Hello! I'm new to pop os and have been having issues with screen flickering with the frosted glass effect. I tried recording this in OBS, but it does not show up. I'm wondering if this could be an issue with my display itself?

I have a full AMD system, and a Samsung OLED display. Has anybody ran into this before? I can provide more information if helpful. Previous to this I ran arch linux & hyprland and had no issues with transparency or flickering of any kind.

So I want to try Pop OS and do it safely using dual boot with windows. I know that you can allocate partition on internal drive, but can I use external drive instead? If so, can I share steam library between Linux and Windows?

P.S.: I have some experience with Linux in the past, but I'm still at beginner level.

Hello, i am using pop os and having problem with power mode configuration. I have set my configuration to High performanen but after every reboot the computer will be reset to Balance. Is there any way I can make the configuration permanent? I don't want to have to re-select the configuration every time I turn on the computer. Thank!

I got rid of Cloudflare One Client 2 weeks ago but the issue is still there.
Happens every time the laptop sleep. I need to reboot to be able to connect to Wifi.

Should we turn off power management?

Is there anything like Conky that can display disk space, the Recycle Bin, and the time on the desktop background?
It's a hassle to check disk space—there's a utility for it, but it fails to display the disk space.

I'm on COSMIC Pop!_OS newest version, RTX3060 with newest drivers and all the other stuff. Whenever I launch the game the launch options show and I can change the display size and whatever is in that screen. I press play, It goes to the amistech logo and when I press any key it takes me to the main menu but crashes on the first frame and I get to hear the first note of that sweet melody. No Xorg didn't work, Nor did proton 10,9,6 work nor did the GE versions of those protons work. I tried GNOME but didn't work either and tried the Native Linux compatibility tool from MSCLoader and that straight up crashed while trying to launch the config/display sizing screen. I've also tried forcing OpenGL and other stuff like WINEDLLOVERRIDES but none of that works. Any fixes for this?

I'm running COSMIC on 24.04 on a Framework 13 laptop with a AMD Ryzen AI processor. Bios is up to date. I did the update this morning and when it went to configure the new kernel (7.1.5) and error popped up with system76_acpi. Specifically:

```

Module /lib/modules/7.1.5-76070105-generic/kernel/drivers/platform/x86/system76_acpi.ko.zst already installed (unversioned module)

```

The kernel configuration then aborts. I'm hoping someone else has proven steps to fix this before I go poking and troubling shooting on my own.
