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.

ERROR winit::platform_impl::platform] X11 error: XError { description: "BadMatch (invalid parameter attributes)", error_code: 8, request_code: 149, minor_code: 4 ) os info: ```sh kernel: 6.9.3-76060903-generic

distro: DISTRIB_ID=Pop DISTRIB_RELEASE=22.04 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="Pop!_OS 22.04 LTS" ```

There are no updates available via sudo apt update && apt upgrade as of time of this post, and this is from an xorg session. ```sh ~$ ps -e | grep -E '(Xorg|wayland)'

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?

I've been trying to create a new cpuset to run some programs with a reduced set of cpu cores, but I seem to be fighting with something my system is already doing because the instructions from the kernel manual don't work. I find cpuset is already mounted, but when I create a directory in /sys/fs/cgroup/cpuset it does not end up with cpuset.cpus in it. It seems cpusets are aleady being used by something else, so not sure how I'd go about this?

The only thing that is stopping me from daily driving the pre-alpha is the fact that I can't get my VPN to connect.

Troubleshooting steps so far:

• Everything suggested on the notification in the screenshot, including restarting, signing out, and trying other servers.
• Using the Advanced Network Configuration app as suggested by @mmstick in a Reddit post. Tried importing a Proton VPN configuration and entering the OpenVPN info manually.

It connects just fine in the current Gnome DE, and I don't have enough know-how to understand what's not working in COSMIC.

back in March, I saw someone posted about this.. now that few weeks had passed, what was the announcement? Did I miss something?

there was no updates in last week. I'm sure the team is working hard on the cosmic de and other refinements.

👍

Hi, I recently installed pop!_os on my shiny new gaming desktop and I'm loving it so far. But I'm now trying to get some games to work (mostly Helldivers 2 right now, which does work after a fresh install, but then freezes on a blackscreen with all subsequent launches. I'm assuming this is due to that awful kernel level anti cheat somehow)

Long story short, according to the fine folks over at protonDB, gamescope can help. But I can't find it on the pop shop or with apt-get. If anyone can point me to some trusted PPA I can use, or the dependencies I need to build it from source, that would be very appreciated (or even, just how to find out what dependencies I am missing. I lost my linux-fu after a long period of using Windows exclusively but I'm not a complete noob)

Additional infos : I used the Nvidia installer, 550 drivers (I have the RTX 3080 Ti), have the Nvidia drm modeset enabled, and I'm using the pop_os Steam package. I also enabled "force full composition pipeline" in Nvidia settings actually I just disabled it because it was causing issues with some other games that were running fine without it

My laptop is running modern hardware with NVME drive and has 64GB of RAM. Running Pop!_OS 22.04 with Gnome/Wayland.

When I launch the cosmic-store or cosmic-edit (for example) via command line or launcher, each takes about 25 seconds for its app window to load. Loading the Pop Shop in the same fashion takes less than 1 second.

I saw a few lines indicating files couldn't be opened, and thought at first maybe my ulimit was set incorrectly, but there is plenty of headroom on my user (soft limit: 4096, hard limit: 1048576).

I do see a handful of logs that look questionable:

May 04 07:50:59 rosie systemd[2109]: app-gnome-com.system76.CosmicEdit-17126.scope: Couldn't move process 17126 to requested cgroup '/user.slice/user-1000.slice/[email protected]/app.slice/app-gnome-com.system76.CosmicEdit-17126.scope': No such process May 04 07:50:59 rosie systemd[2109]: app-gnome-com.system76.CosmicEdit-17126.scope: Failed to add PIDs to scope's control group: No such process May 04 07:50:59 rosie systemd[2109]: app-gnome-com.system76.CosmicEdit-17126.scope: Failed with result 'resources'. ░░ Subject: Unit failed ░░ Defined-By: systemd ░░ Support: http://www.ubuntu.com/support ░░ ░░ The unit UNIT has entered the 'failed' state with result 'resources'. May 04 07:50:59 rosie systemd[2109]: Failed to start Application launched by gnome-shell.

What could be causing the cosmic apps to load so slowly?

COSMIC Tweaks gives you granular control over everything you can do in COSMIC.

This app aims to help you tweak settings that are not currently available in COSMIC Settings.

Here's what the app can do so far:

• ✨ Color schemes: Save your current theme and import other themes to use anytime you want.

• ⚙️ Panels: Fine-tune your panel padding and spacing.

COSMIC Tweaks is just getting started, and more features are on the way!

Hey,

Lately there was a post on reddit about request for WebApp Manager for Cosmic desktop.

Few months ago I was working on WAM Rust so "web app manager" written in Rust and Iced-rs. Yesterday I decided to rewrite it to libcosmic so it will looks nicer and integrate with Cosmic desktop better.

The result is awesome. I'm happy how it looks.

This is very first working version of this app, so it's working with mainly mainstream browser and maybe there will be some fuckups. However I will try to do my best to finish it so it will work better and just like Linux Mint's "WAM".

If you are interested in this app, you can follow my progress on github: https://github.com/elevenhsoft/cosmic-wam

Have a nice day and wait patiently for Cosmic desktop :)

p.s.

Sorry for copy paste from reddit. It just faster to do than uploading again and again :)

I'm trying to print some documents in grayscale / black & white but it keeps printing my documents in colour instead, even if I select grayscale in one of the drop down menus in the settings (under Color > Color Model).

Does anyone know if there is a specific setting I need to change for it to print in grayscale correctly? If it helps, I have a Canon MX420 printer.

Thanks so much for your help!

My Bluetooth isn't working. It's not even detected by the rfkill list command. Since installing various Linux distributions, I've had persistent Wi-Fi issues. To fix those, I used this repository: repo: https://github.com/lwfinger/rtw88.

Important: This rtw88 repository is for Wi-Fi only. The kernel drivers btusb and btrtl (located in the drivers/bluetooth directory) are used for Realtek Bluetooth devices.

While Bluetooth works after manually loading btusb, it doesn't load automatically. Here's my question:

• How can I configure btusb to load automatically at boot?
• Alternatively, what might be causing btusb not to load automatically?

Hello, I'm making this post because I'm having some issues with NVIDIA driver and I want to revert back to an older version.

Since version 535 I've been having troubles with the driver on XWayland, specifically while playing games (black horizontal bars flickering on the screen, tearing, stuttering). The last version of the driver that was working well was version 525.

Is there any way I can install nvidia version 525? Executing $ ubuntu-drivers devices the last version I can find is 535.

Thanks to anyone willing to help

Update: I tried to add the ppa from here "https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa/+packages" and manually install the desired nvidia driver version, alongside all the dependencies needed, but the linux kernel it was targeting was version 6.2. I don't know if the problem was generated because of this, but after I finished the installation, only one monitor was working, animations were choppy and nvidia-smi was not working. Basically something was wrong and the driver was not working.

Update 2: Posted solution in the comments.

I only have one monitor plugged into my desktop PopOS 22.04 LTS install. Recently my display settings shows two displays with one being the correct Samsung one and another just as "Unknown Display".

I am running NVIDIA Graphics and the About reads: NVIDIA Corporation TU106 [GeForce RTX 2060 Rev. A]

With nvidia-driver-550 installed. Any help would be appreciated!

Hi, I brought this up to support and they haven't been able to figure it out, so i figured I'd put some more lines in the water.

Specs: Oryx Pro 11 (2024, i think its 11) Nvidia RTX 4060 Laptop, 545 firmware 24-core Intel i9 CPU 16” 1200p display (165Hz)

I have display issues, I'm running two monitors. One monitor through the HDMI port and the other through usb-c. The HDMI port typically always works. The usb-c port generally doesn't. The computer also usually resets my monitor positions and then changes my resolution.

I have looked through journalctl, and did Nvidia logs and that yielded nothing of use (at least from what I can tell). Looked at dmesg and didn't find anything wrong (at least from what i can tell). Couldn't pinpoint one specific thing. I made system76 logs (gave it to them) and they say the monitor is indeed being seen as connected and there is nothing out of the ordinary.

Most of the time i have to try and restart a few times for the usb-c monitor to catch in the right resolution, but most of the time it is either in the wrong really low resolution, or a black screen. When it does work, it works as long as i have the computer on (granted i don't have it go to sleep or suspend).

I have tried multiple Linux flavors, but generally I will get the same type of issues. I did Ubuntu and rolled back to the 535 Nvidia Driver, and that didn't seem to fix the issue. I've bought multiple cables and tried multiple monitors.

At this point I'm not sure where I should look and support hasn't been able to really help me fix this issue. Anyone have any ideas?

Thanks

I just noticed two finger scrolling with my touchpad now has momentum... I haven't noticed this in other distros and I forgot how much I missed it since moving from macOS. Hell yeah, amazing work folks!

When I'm trying to pick a file say when I click Browse on the Image section of making a Lemmy post the file manager doesnt have a button to change the View to Grid so I can see what the image I'm selecting is. I can't tell what image is what by the tiny preview

Ever since I switched to Pop OS whenever I google certain stuff I get this message where google thinks I own crowdsupply

I noticed the newest kernel package is named "linux-image-6.8.0-76060800daily20240311-generic".

Why is it named daily? Does it mean we will be getting more frequent kernel updates? Or just some daily build that someone forgot to change its name?

github says it is done but i donnot see it in pop store when is it available?

I started using linux a couple of years ago and it was pop os that im still using today. When i started, apps many was across all screen, it was big and strange to me that on desktop computer its all so big and apps icons are to big.. But luckly that was changed after some time and now we have much smaller widow with apps and thats much better, but i think that its still to big and that it should be smaller. Im i the only one that think this way..? Is there a chance that it could be updated with new cosmic “Rust” release?

The application is still being actively developed but I wanted to share my experience working on it.

While working with libcosmic, a pre-alpha library, I was pleasantly surprised by the available resources. Unlike many early-stage projects, libcosmic has well-written documentation that clearly explains core concepts and functionalities. Beyond the documentation, the project provides practical examples showcasing common use cases and real applications being actively developed.

But libcosmic's true strength lies in its community, the team at S67 has been incredibly supportive, not only did they answer questions promptly but also actively contribute to the project's growth. This kind of collaborative spirit fosters a welcoming environment for developers of all levels.

I've had the opportunity to contribute back to the project and my contributions were well received, the willingness of the S67 team to collaborate and integrate contributions ensures that libcosmic will continue to evolve and empower developers to create next-generation desktop applications.

Join the community, delve into the code, and be part of shaping the future of COSMIC.
