Linux

Hey all,

Anyone familiar with the state of Raptor Lake performance + efficiency cores in Linux? I'm specifically curious about how the kernel balances things when running multiple containers (without pinned CPUs)

Thanks!

It's fixed now.

Before it worked.

I have a server running Debian that has been connected to WiFi for a long time, but I have since moved it and given it a wired connection. It still seems to be using WiFi though, and in my router settings it shows up as connected through WiFi and not through ethernet.

Now I want to make sure that I can switch over from WiFi to ethernet directly from an ssh-connection so I won't have to connect a screen to get direct access.

What is my best bet here? A lot of the tools I find used for different network operations are not pre-installed, and I don't want to be installing just everything being suggested. Can I solve this by installing network-manager and using nmcli?

EDIT: I also want to disable the wireless card.

EDIT2: No eth-interface shows up when running ip link show, EDIT3: but r8169 0000:02:00.0 enp2s0: renamed from eth0 shows up in dmesg and enp2s0 shows up in ip link show, so I guess it is recongized then.

[SOLVED] EDIT4: I made the modifications manually in etc/network/interfaces, and now it seems to work. I entered the following lines:

auto enp2s0
iface enp2s0 inet dhcp

And then it showed up in my router. I then continued to comment out the lines enabling the wireless interface, and after reboot it works fine still.

Ok, getting Linux setup as Windows enshitiffication continues...I installed Arc Menu and it's almost perfect, but the app categories have mostly themed icons, just a few of them don't. Any way to change these last 5 icons on the far-left side?

EDIT: Solved. Took me longer to figure out than I want to admit, but in my case, those category icons were coming from Zorin OS's built in menu settings. So I launched the "Main Menu" from Arc Menu, which brings up Zorin's menu editor.

Then clicking on "Applications" shows the categories, at which point I could right-click on a category, then "properties" and click on the icon

The system icons are stored at /usr/share/icons -- browse to the right icon, select it and restart gnome (or log out and log back in)...everything is fixed. Hope this helps someone else save a bit of time down the road 🤷

KDE, Gnome, Gamescope and now Wlroots already have a working implementation of the protocol.

2025 Year of the Linux Desktop.

I've seen this video of Timothy Roscoe at USENIX ATC '21 recently and was very interested in multikernel OSes.

While Barrelfish is abandoned, it seems that Kirsch is his successor.

However, since I've seen this video I wonder what changed since the keynote, why it doesn't seem to be a thing for mainstream kernels and if there was any roadmap/will to expand mainstream kernels like linux to embrace the whole hardware.

Do you have any pointers/ideas or resources to share on this?

I have a server running Debian 12. It seems to hang up and freeze sometime between 12 hours and like 2-3 days. I really want to see what's happening, but I can't access my containers with the web UIs, can SSH, and adding a monitor shows the DE completely frozen. Rebooting fixes it for a while, but it locks up again after some time.

I had the same issue with 10 year old hardware so I threw together a "new" machine with some spare parts and it still happens I also tried rocky Linux and the same thing happened on both machines.

Any help and direction would be greatly appreciated!

I'm trying to use Android Studio, but the virtual android doesn't start because of KVM error. Tinkering around with another VM application I understood that it's a location/permission issue (flatpak Gnome Boxes had the same issue, couldn't load KVM, but Boxes installed via terminal worked and I could start a VM).

On the official Android Studio website they suggest extracting the tar.zip in /usr/local but the system doesn't allow me to, so I extacted it on the desktop and the app runs, but I get a "/dev/kvm is not found" error, which should be because of the location I'm running Android Studio from.

So, should I just sudo force move the folder of Android Studio from desktop to /usr/local or is there a better way to do it?

PoP_OS just in case it can be useful to know.

Thanks in advance!

edit: fixed it by updating BIOS to latest Beta. Can't believe it was a bug in the version I was running and no one else catched it, since Beta changelog didn't mention it.

I created a simple alias for xargs, with the intend to pipe it when needed. It will simply run a command for each line of it. My question to you is, is this useful or are there better ways of doing this? This is just a little bit of brainstorming basically. Maybe I have a knot in my head.

# Pipe each line and execute a command. The "{}" will be replaced by the line.
# Example:
#   find . -maxdepth 2 -type f -name 'M*' | foreach grep "USB" {}
alias foreach='xargs -d "\n" -I{}'

For commands that already operate on every line from stdin, this won't be much useful. But in other cases, it might be. A more simplified usage example (and a useless one) would be:

find . -maxdepth 1 | foreach echo "File" {}

It's important to use the {} as a placeholder for the "current line" that is processed. What do you think about the usefulness? Have you any idea how to use it?

so if you have some reason to want such a thing, well I guess it exists. github.com/chep/copilot-chat.e…

I'm proud to share a major development status update of XPipe, a new connection hub that allows you to access your entire server infrastructure from your local desktop. XPipe 14 is the biggest rework so far and provides an improved user experience, better team features, performance and memory improvements, and fixes to many existing bugs and limitations.

If you haven't seen it before, XPipe works on top of your installed command-line programs and does not require any setup on your remote systems. It integrates with your tools such as your favourite text/code editors, terminals, shells, command-line tools and more. Here is what it looks like:

Reusable identities + Team vaults

You can now create reusable identities for connections instead of having to enter authentication information for each connection separately. This will also make it easier to handle any authentication changes later on, as only one config has to be changed.

Furthermore, there is a new encryption mechanism for git vaults, allowing multiple users to have their own private identities in a shared git vault by encrypting them with the personal key of your user.

Incus support

• There is now full support for incus
• The newly added features for incus have also been ported to the LXD integration

Webtop

For users who also want to have access to XPipe when not on their desktop, there exists the XPipe Webtop docker image, which is a web-based desktop environment that can be run in a container and accessed from a browser.

This docker image has seen numerous improvements. It is considered stable now. There is now support for ARM systems to host the container as well. If you use Kasm Workspaces, you can now integrate the webtop into your workspace environment via the XPipe Kasm Registry.

Terminals

• Add support for the new Ghostty terminal on Linux
• There is now support for Wave terminal on all platforms

Performance updates

• Many improvements have been made for the RAM usage and memory efficiency, making it much less demanding on available main memory
• Various performance improvements have also been implemented for local shells, making almost any task in XPipe faster

Services

• There is now the option to specify a URL path for services that will be appended when opened in the browser
• You can now specify the service type instead of always having to choose between http and https when opening it
• There is now a new service type to run commands on a tunneled connection after it is established
• Services now show better when they are active or inactive

File transfers

• You can now abort an active file transfer. You can find the button for that on the bottom right of the browser status bar
• File transfers where the target write fails due to permissions issues or missing disk space are now better cancelled

Miscellaneous

• There are now translations for Swedish, Polish, Indonesian
• There is now the option to censor all displayed contents, allowing for a more simple screensharing workflow for XPipe
• The Yubikey PIV and PKCS#11 SSH auth option have been made more resilient for any PATH issues
• XPipe will now commit a dummy private key to your git sync repository to make your git provider potentially detect any leaks of your repository contents
• Fix password manager requests not being cached and requiring an unlock every time
• Fix Yubikey PIV and other PKCS#11 SSH libraries not asking for pin on macOS
• Fix some container shells not working do to some issues with /tmp
• Fix fish shells launching as sh in the file browser terminal
• Fix zsh terminal not launching in the current working directory in file browser
• Fix permission denied errors for script files in some containers
• Fix some file names that required escapes not being displayed in file browser

A note on the open-source model

Since it has come up a few times, in addition to the note in the git repository, I would like to clarify that XPipe is not fully FOSS software. The core that you can find on GitHub is Apache 2.0 licensed, but the distribution you download ships with closed-source extensions. There's also a licensing system in place as I am trying to make a living out of this. I understand that this is a deal-breaker for some, so I wanted to give a heads-up.

Outlook

If this project sounds interesting to you, you can check it out on GitHub or visit the Website for more information.

Enjoy!

I installed LXDM and LightDM, I couldn't login from the DM in either cases, so I decided to run LXQt using startx which worked, except I couldn't sudo from the terminal emulator inside LXQt, while I was able to sudo normally in tty, I've tried enabling elogind, nothing changed, my user is in the wheel group and my system is up to date

Hello everybody! here's the problem: In my EndeavourOS laptop I had a /swapfile, but couldn't take snapshots with snapper because of it (if I understood correctly). So, I created a 16Gb swap partition using GParted from a live USB. Then, I edited /etc/fstab to remove the line about the swapfile and to add the newly created swap partition:

UUID=506d48e6-1cc0-4136-ba55-6f2f187bcdb1   swap           swap    defaults   0 0
# /swapfile                                   none           swap    sw         0 0

I took the UUID from

$ sudo blkid  
/dev/nvme0n1p3: LABEL="swap" UUID="506d48e6-1cc0-4136-ba55-6f2f187bcdb1" TYPE="swap" PARTLABEL="SWAP" PARTUUID="b4543e4e-4623-4317-99aa-086b0e62836e"
...

if I run sudo swapon -a it gets enabled correctly and it all works fine. The problem however is that when I reboot the machine, it gets stuck in the systemd screen saying "a job is running for /dev/disk/etc..." forever, and the only way I have to log in is to boot from a live USB, modify /efi/loader/entries/somethingverylong.conf to add these kernel options:

systemd.swap=0 noresume

and then reboot, and manually enable the swap.

I'm not understanding very well what's happening here. why is the system stuck if I don't add these parameters? how can I solve it?

thanks in advance!

What are the best ways to run a game on sandboxed mode with only game HDD shared to it. There should not be network access for the game and there should be GPU (intel integrated) pass-through.

I have tried Gnome boxes, but GPU pass through is not working and checked distrobox, but that too shares HOME folder.

Update: I have installed Bubblejail and sandboxed Alacritty. Shared a Directory in with it on Home and disabled network. Since my game is launched using a shell script, I use this setup for it.
