So which one is actually official one? I can't describe what "official" mean here, maybe the one that actually came from reddit or the one with more subsscribers or one with more activity ?

Also Why there are multiple copies of same community in different instances? Isn't the whole point of lemmy is that it is federated?

It peaked at 4.05% in March. The last 2 months it went just below 4% as the Unknown category increased. For June the reverse happened, so 4.04% seems to be the real current share of Linux on Desktop as desktop clients were read properly/werent spoofed.

Hi ! I'm a little confuse between all immutable versions based on fedora. Is this correct : universal blue = tool to create image, based on fedora atomic desktop ?

With universal blue, they created :

• Bluefin = gnome
• Bluefin-DX = gnome + developper tools
• Aurora = kde
• Aurora-DX = kde + developper tools
• Bazzite = games

What the difference between silverble and bluefin for example, and which are you using ?

Can I delete previous backups, without affecting following backups, Since TimeShift (RSync) make increamental backups.

i'm picasso.

I have been using a company computer running Ubuntu 22.04. There are frequent and unexplained problems, like segmentation faults, stack errors, files disappearing, computer freezing or not booting, or turning off immediately after I turn it on. I don't know what to do. The IT staff came to my office to check the computer and said "it was all good." I am not allowed to boot from a USB stick or enter BIOS or open the case. I ran a command line memory check several times with no errors. There is an NVIDIA card, but it's running X.org and usually headless. I mostly set up tasks via SSH.

What would you do?

i recently switched to connman and i need a tui. so i searched for some and got:

• connman-ncurses
• cmtui

but i believe both are orphaned. so it there any tui for connman out there?

Hello! My disk space was out of space left, so I decided to remove some snapper snapshot. snapper list listed over 360 snapshots. I removed them, and freed 50Gb of space. One of these hasn't been deleted successfully:

Cannot delete snapshot 166 since it is the next to be mounted snapshot.

it's description is writable copy of #156. How can I remove it? should I do it using btrfs subvolume delete?

here's the output of sudo btrfs subvolume list -t /:

all those timeshift subvolumes are there because before snapper, I used to use timeshift. I tried to remove them:

sudo btrfs subvolume delete timeshift-btrfs/snapshots/2023-09-18_18-25-33/@/var/lib/machines

If I understand correctly, it means that I should give an actual "system" path instead of the path in the table, but I don't understand which path

thanks in advance to everyone!

First, before this rather large infodump, I want to thank anyone that takes the time to read through this to offer any information or advice on trying to resolve this issue.

Here’s the issue I’ve been struggling with.

I keep getting this error on my server:

INFO: task txg_sync:1615 blocked for more than 241 seconds.
Tainted: P           O      5.15.0-112-generic #122-Ubuntu

Background:

I’ve got a homeserver running Ubuntu server 22.04 (no DE) with an Intel Core i7-6700K CPU @ 4.00GHz, 32GB RAM, and two ZFS pools. The OS is installed on its own 128GB SSD, and the two ZFS pools consist of a 128GB SSD in its own pool for the server’s cache, and a 4x8TB HDD RAIDZ1 pool that is my main data/server storage (much more detailed system info below).

I have a bunch of services running in Docker containers, and overall everything is great, except for when that error rears up.

The error seems random, but occurs most reliably, but not consistently, when I’m trying to write larger media files to the RAIDZ1 pool. I am aware that this an IOPS issue, but so far I have not been able to diagnose it.

Back in February, I was carrying some boxes down to the basement where the server rack is, and I accidentally kicked a stool into the server which knocked the shit out of it (it’s a tower pc that I built back in 2016 or 2017 and repurposed in 2020ish to server use). When I turned on the monitor it was in total panic mode. The screen was gibberish colors and flickering madness.

I had to force shutdown with the power button. I waited a good couple of minutes, and on reboot, everything seemed fine. Until I noticed the new txg_sync error a week or so later when I went down to add some media to the server.

After a lot of searching and reading that didn’t turn up pertinent info, I ran across a comment that said this error is almost always hardware related. Like a loose connection or a failing disk or something. With me having knocked the shit out of the server, I realized I should have opened the case up and checked it all out. I shut it down, opened it up, and found a loose connector on the motherboard. I reseated it, checked everything else (though not thoroughly enough, which we’ll get to), and rebooted hoping I had found the problem.

It seemed fine for a bit, but no luck. The error returned.

More searching with no luck, and then about a month ago, a friend he suggested I check all the SATA connectors by disconnecting each one and reconnecting to insure a good, solid connection. I had previously checked if they were seated when I opened the case, but didn’t disconnect and reconnect. While doing this, I found a SATA cable with a busted clip and thought again I had found the problem. I replaced the cable, and went about a week before the error resurfaced.

It continues to occur, as I mentioned inconsistently. Most reliably, but not always, when writing data to the RAIDZ1 pool.

I have run a thorough memtest, and there were no errors or issue with the RAM, and as far as I can tell, there are no errors/failures with the HDDs.

Below is a lot of system info, and an example of what I find in dmesg for the error.

Thank you again to anyone who takes the time to offer any info or advice on resolving this.

I'm working on my transition plan away from Windows and testing out various things in VMs as I do so, and one big hurdle is making sure the VPN client my work requires can connect. Bazzite is my target distro (primarily gaming, work less frequently), though other more traditionally structured ones like Pop!_OS and Garuda are possibilities.

I'm currently trying and failing to get the VPN client working in a distrobox (throws an error during connection saying PPP isn't installed or supported by the kernel). However, I can successfully get the VPN connected if I overlay the client and its dependencies via rpm-ostree install, but I read somewhere that Bazzite's philosophy is to use rpm-ostree as sparingly as possible for installing software to preserve as much containerization as possible.

Since I can get it working outside of a container, am I overthinking it? Should I just accept that this might be one of the "sparing" cases? Is Bazzite perhaps a poor fit for my use case? I've been trying to make sense of this guide, but I'm having trouble understanding how to apply it to my situation, since I'm not that familiar with Docker or Podman.

After recently Firefox update I noticed that audios are cluncky. I mean, if my Firefox isn't playing any sound, if I start a video or any sound start playing (whatsapp notification, for example) it doesn't work at first. For example in videos, I have to pause and unpause the video to the audio start playing properly.

Is anyone experiencing something similar?

Is there anything I can do to solve this issue?

I tried another browsers and another sounds in OS and it doesn't happen, what makes me think it's not an OS bug, but a Firefox bug.

According to this issue, it looks like there are no plans, understandably, for making a version/fork of nsxiv but with native Wayland support.

Any recommendations for a simple image viewer in Hyprland?

Hipoople,

I have trying sway in Manjaro and the icon for evolution mail in the try par is nto showed. Any idea?

I currently have an AMD video card (6700 XT) and Wayland support is excellent. Also, multi-monitor support in Wayland works perfectly.

So what's your experience with Nvidia's 555 driver in Wayland? Those using it in conjunction with KDE 6.1, what's your experience with multi-monitor VRR? I ask about VRR because I heard that multi-monitor VRR in Wayland is still problematic.

This is for my own curiosity if an Nvidia video card could be considered as an upgrade option.

Are we Wayland yet? Are we JPEGXL yet? Are we Rust yet?

I’ve gathered a meta-tracker for the adoption state of futuristic technologies.

I have a desktop and a steam deck. I would like to setup some old games I have on disc on the desktop. Then compress them and decompress on my Steam Deck without doing the full install again. I understand that with wine/proton prefixes they should be installed to a "fake c:/ windows hierarchy" can I just compress that and copy to a different Linux machine? Does it save which proton version was used? If I use something like Lutris or bottles can I import into them?

Hi everyone,

I am very new to Linux/GNU amd I have moved from windows to Fedora workstation 40 with GNOME a few moths ago.

I have been blown away how easy everything have been to migrate but there is one thing I can't migrate which is proton drive as they don't support Linux 😡.

I decided to follow some advice online and set up a windows VM in GNOME boxes and install proton Drive then I can copy/mount my files leaving the VM to sync my proton drive.

I have insralles spice on both the Host and the Guest OS and can copy filed to the VM but I can't for the life of me work out how to get from the VM.

I am probably being stupif but please be gentle I have only been using Linux for 2 months.

Thanks in advance.

Yesterday, I made this post about getting my old Xbox 360 controller working wirelessly on Manjaro. The comments suggested using xpadneo- more specifically xpadneo-dkms. xpadneo-dkms only works Xbox One and Series X controllers. Doing a little more research, I came across xboxdrv. I installed the AUR package but gave me an error message saying that I was missing two dependencies: scons and glib2-devel. scons installed with but glib2-devel has been a bit tricky. If I used yay -S glib2-devel it returns this error: -> No AUR package found for glib2-devel there is nothing to do. If I use sudo pacman -S glib2-devel it returns this error: error: target not found: glib2-devel. I could go on but we would be here all day. Any help? Thanks in advance.

I'm 43 and not really starting using Linux. I've dabbled with distros on and off over the years, but I never made the full switch because work always had some program or policy that just wouldn't play nice with Linux. With all the crappy Microsoft decisions, bloatware, and ads I decided to try and use Linux exclusively on a personal device, and I'm absolutely loving it!

I've been working with Ubuntu as my main distro, and I've also been playing around with distros on a Raspberry Pi. To really challenge myself, I installed Linux on an old Surface Pro 3, and guess what? It just works! I was pleasantly surprised by how smooth the setup was and how well it performs.

I missing any key steps or tips to make the experience even better on a Surface? Any insights would be greatly appreciated. I was planning to buy a new tablet that runs Linux but this is working better than expected. I'm really enjoying the flexibility and control Linux offers and want to keep this momentum going.

I have read up and tried plenty, just looking for some perspectives out there specific to your tablet experiences.

EDIT Thank you for all the suggestions and insights! I'm going to continue using the Ubuntu build for the next few months. Still lots more to learn, but I'm excited to see how this goes. I have everything setup I need to function as a Linux only tablet experience. no more dependency on Windoze.
