Because I'm using a lot of audio software and the Ardour DAW on my Lenovo T420, I want to use a RT kernel. However, if I install the stock Debian RT kernel, there seem to be modules missing which affect my ability to adjust my console fonts and resolution, and I'm also missing whatever modules are necessary to drive my built-in Intel sound device.

If I build a custom kernel with the source downloaded from kernel.org , I can build a kernel which does have those missing modules, but is only a dynamically preemptible kernel, not a full realtime kernel.

If I issue uname -a for my current kernel, I see ". . . 7.2.11 #1 SMP PREEMPT_DYNAMIC . . . " I'd like to create a 7.3 RT kernel which also builds all the modules I have in the 7.2.11 kernel, but is configured to be RT. I've tried using the RT patch available from kernel.org, and patching that against the downloaded 7.3 source, but then I no longer get the modules pulled in from 7.2.11, even if I use make localmodconfig.

When I use synaptic to view upgradable items many of th eitems have no change logs. Why is this occurring?

Hello

yet another post about wifi speed problems on Debian; I digged around but could't find a solution working for me.

So here it is, I am experiencing slow speed with my wifi (and only on my linux laptop). Sometimes it works then it stops working suddenly ; sometimes rebooting can fix the problem. But it seems I cannot get a consistent speed on my wifi.

What I tried :

- reinstalling / changing the firmware

- disabling power management

Any hints would be really appreciated.

Thanks !

Greetings. I have an old Macbook Unibody. It currently runs MacOS X (all it can do), and I was wondering if I could put Debian into it. I don't want it to be the only OS on it, though, so I would partition the disk in half. Is this feasible? If I do go the full-partition route, could running a Mac VM be more successful on it?

best,

me

edit: thank you all for your comments. i think i'm going to try the opencore legacy patcher suggested by u/Nymunariya ! if that fails, i will fall back on dual-booting. i'd like to keep the macOS because i need it for iTunes. this is because i don't like apple music.

I know that this is not necessary and interesting for everyone, but... how will things be on Debian? Will the anti-cheat work with Nvidia dkms driver from nvidia cuda?

My goal is to make a partition of my ssd in the Debian installation usb. I cannot do it in windows.

Usually, this would just be selecting “manual” as the format when setting up the disk, but when I do that, only the usb flash drive itself shows up, and not the ssd itself. I tried going into busybox and using fdisk but that didn’t work, and neither did cfdisk or part.

After I partition it, I will use the free partition to install Debian and dual boot windows

Containerized Debian package builds, artifact diffs, and automated maintenance, test running, new upstream imports and more. If you previously struggled with .deb work, this might make things a lot easier now.

So I'm a full time casual desktop Linux OS user since a little before Debian Squeeze (is that like 2008/09ish?). Not a developer.

I'm probably late to the party, but I extremely lightly skim Linux and open source news now and then and I recently noticed the Linux kernel allowing AI was a serious issue for some, it almost sounded like they had a moral issue even. Then I also saw Debian voted to be indifferent about AI and some contributors posted that they were going to abandon Debian due to that, but I have not been able to hear the actual argument against it yet.

As a non-developer spectator, this really surprised me. I took it for granted that in open source, where manpower always seems short, having boosts to productivity would be welcomed, even though there's bound to be growing pains with changes (like being swamped with submissions, I saw). But I discovered there's some that clearly don't see it that way and I'm interested in that.

Can someone try to fairly explain the argument against AI that these people had/have for Debian and open source? Or maybe someone against it can explain for me? Preferably in a neutral journalistic way if possible.

🚀 GassNative — Run a Debian Linux Desktop on Android (ARM64)

Hey everyone! 👋

I'm developing GassNative, an experimental Android application that brings a Debian GNU/Linux ARM64 environment and an XFCE desktop experience directly to Android devices — without requiring root access.

🐧 What GassNative offers:

- Debian GNU/Linux 13 (Trixie) ARM64 environment.

- XFCE4 Linux desktop.

- Integrated Android application interface.

- Linux terminal and compatible desktop applications.

- Environment profiles and settings.

- Automatic startup update checking.

💡 The goal: Turn an Android smartphone into a portable Linux environment for experimentation, learning, and working with compatible Linux software.

🛠️ Current status: GassNative is actively under development. Application compatibility, installation time, and graphics performance depend on the device and configuration. Hardware-accelerated desktop rendering and further desktop integration remain ongoing work.

🔗 Explore the project:

- 💻 GitHub repository and source code: https://github.com/Gass-OS/GassNative-

- 🌐 Official project website: https://gass-os.github.io/GassNative-/

I'm building this project under GASS-OS, and I'd love to hear from the Linux, Android, and open-source communities.

What features would you like to see next? Have you tried running a Linux desktop on your Android phone?

Feedback, suggestions, and bug reports are welcome! 🙌

GassNative — Your Linux world, in your pocket.

KDE and Debian on iPhone!

LinuxRunner brings Debian ARM64 to iOS, including desktop environments like KDE Plasma and apps like Blender.

No jailbreak, JIT, or virtualization needed. It runs Linux binaries through an ARM64 interpreter.

Still early in development, but pretty interesting to experiment with. Feel free to try it out!

They both used to point to the Canadian mirror, but when the first one refused to update PHP, I changed the first one to the main repository source but that didn't help.

This is driving me absolutely crazy, the machines are on the same network, same switch, same router. the only difference between them is one has 48GB of memory the other has 16GB memory, and the first one runs docker the second one doesn't, but that shouldn't matter...should it?

TIA...your very thankfully the insane ;-)

I've been trying to setup unattended-upgrades to update tailscale along with the rest of the system. However whenever I try doing a dry run it doesn't seem to catch it even though I checked and made sure an upgrade is needed at the moment.

Here's my current config for sources.

Unattended-Upgrade::Origins-Pattern {

// Codename based matching:

// This will follow the migration of a release through different

// archives (e.g. from testing to stable and later oldstable).

// Software will be the latest available for the named release,

// but the Debian release itself will not be automatically upgraded.

"origin=Debian,codename=${distro_codename}-updates";

// "origin=Debian,codename=${distro_codename}-proposed-updates";

"origin=Debian,codename=${distro_codename},label=Debian";

"origin=Debian,codename=${distro_codename},label=Debian-Security";

"origin=Debian,codename=${distro_codename}-security,label=Debian-Security";

// "o=Debian Backports,n=${distro_codename}-backports,l=Debian Backports";

"origin=https://pkgs.tailscale.com/stable/debian ,codename=${distro_codename},label=tailscale"

Any help is appreciated.

Hi All,
Version: Bullseye
Im maybe missing something.... But today I go to update and and get all sorts of errors.

Included the pics I have of sources list and the update result.
Is something up with that IP address.

Im happy to update it all the the newest version but this has me lost.
Apologies Debian isnt my main language.

Can anyone help ?

Edit: Sorry for my crap spelling but was rushing... "Debian"

Thanks.

If anyone still (like me) neeed old Debian systems running I made backports for a number os combinations
Best regards to all Debian users

Hey everyone,

I’ve been hopping around various distros for side projects over the last few years—testing rolling releases, heavily immutabled setups, and shiny new tech. But time and time again, I find myself coming back to Debian for anything that actually matters.

In an era where operating systems are becoming increasingly bloated with forced telemetry, unrequested AI integrations, and snap/container layers forced down our throats, Debian stands out like a beacon of sanity. It just works, respects user sovereignty, and sticks to its Social Contract.

What’s interesting to me is that "Debian Stable being outdated" feels like a myth of the past now. Between Flatpak/AppImage for user apps, Backports for modern kernels/drivers, and Podman/Docker for dev work, Debian Stable is arguably the most modern, rock-solid base anyone could ask for without the fragility of rolling releases.

My question to the community:

As Linux continues to gain desktop market share (especially with Linux gaming booming), do you think Debian should maintain its conservative, "quiet giant" approach, or is there room for the project to actively market its stability and ethics to refugees from Windows/Ubuntu?

Would love to hear your thoughts on how Debian can keep its core identity while welcoming the new wave of Linux users.

Cheers to all the maintainers and contributors who keep the universal OS rockin'!

Mint must have been the one eating all my battery because I been on Debian now for a few days and my battery lasts sooooooo much longer! Its the little things that make me so happy. I'm done hopping around I found the one for me and its Debian, but I do hear Fedora is really good too. LOL. Maybe both for me.

Im just making myself a little app to add/remove the repo for the Nvidia drivers and then enable you to select the right nvidia driver in the gui, as i currently dont use them myself (yet) do you guys add the nvidia repo directly or do you use the repo setting in extrepo from within Debian? So far i was adding the external nvidia repo directly

Hey everyone, does anyone else experience a bug on Debian 13 Stable where characters keep repeating/getting stuck as if the key is still pressed?

This happens with both the laptop's built-in keyboard and Bluetooth keyboards. I've noticed this issue specifically on Debian, while other distributions with the exact same hardware don't have it. The bug is intermittent and only happens sometimes.

System Specs:

OS: Debian GNU/Linux 13 (trixie) x86_64

Host: Dell Latitude 3420 (Intel i7-1165G7)

DE/WM: GNOME / Mutter (Wayland)

Kernel: Linux 6.12

Has anyone run into this or know how to fix it?

Just moved my mum who's 79 from her Windows laptop onto Debian with GNOME de and she loves it, just gave her one of my old Lenovo, i7 6th gen with 16gb laptops. Tbf she only really uses Firefox on it but she was happy that it came with Firefox, she signed into her Mozilla account and away she went, prints first time to her wireless printer too which is all good :)

dell xps 15 7590 - Kernel Linux 6.12.113+deb13-amd64 - FW. 1.9.1 - gome48 - wayland

i don't know since when it's the case but i just saw that and didn't know why it was like that.

someone else has the same problem? is it debian or gnome and what can i do to fix it if it is even fixable for non os dev?
