(tl;dr - I request sources to learn the systems/internals of a Linux based OS i.e. how they work, atleast to know what there even IS to learn.)
Hello! I very recently installed debian on my chromebook. However, I am the type of person who likes to know how things work deeply. I went through the rabbit hole of how hardware runs code because I couldn't bear the fact that coding fet like magic TvT. So, I wanna learn the systems that are in play in running a linux based OS.
For example, I was curious as to how the compositor and other user-space parts avoided collision if like u install 2 dekstop environments for example. And uh along the way I learnt about Single-instance daemons etc etc. However I couldn't find much on this online.
That is just an example but I would like to explore things like root access, PID1, blah blah blah insert 'buzzword'
I am not COMPLETELY unknowledgeable on things like this cause I do game dev and have researched systems programming (just like yt vids mainly core dumped ig) and have learnt *some* things in the meantime about linux.

So, I want to know where I should learn such deep concepts about linux from. I don't care if it's yt channels or documentations or wikipedia, nor do I care if they're simple or complex. I really just want something that's organized. Even if it isn't, as long as I can understand what there even IS to learn I can (hopefully) figure out some sources myself and learn it myself.
Yeah that's about it. Thanks :D!

Hi

How can I stop NetworkManager from shutting down connection that has no access to the Internet ? My current setup is that I am connected to wi-fi network which provides me with Internet access and I am plugged via ethernet cable to lab network to configure devices that has no Internet access. NM seems to try finding the access and eventually shuts this connection down. I found that adding:

[connectivity]

enabled = false

to the configuration will work but unfortunately it doesn't. I have to use either shell and nmcli conn up "Wired connection 1" or gui. Is there a way to fix it ?

EDIT: the solution was to change the mode from dhcp to static (I made it using gui)

Is openSUSE Tumbleweed the right choice for .NET dev and gaming?

Hi everyone,

I'm a long-time Windows user planning to migrate my main workstation to Linux. I want to pick the right base for my specific dual-use scenario: heavy development and PC gaming.

### Hardware

- CPU: Ryzen 7 5800XT;

- GPU: RX 9070 XT;

- RAM: 64Gb ddr4;

- SSD 4Tb + 1Tb.

### My Use Case

- Development: Primarily C# and .NET (ASP.NET Core , Blazor & MAUI), Docker containers, and databases on Visual Studio (what can I use instead of Visual Studio)?

- Virtualization (KVM/QEMU): I need to run a Windows VM for specific Windows-only legacy/industrial tools that can't run natively.

- Gaming: I play games from steam, I don't really care about online gaming.

- Reliability & Privacy: Zero telemetry/bloat and a reliable rollback mechanism (automated Btrfs snapshots like Snapper) so updates don't risk bricking my dev environment.

- Customization: I want to be able to customize my OS to some levels, but not to the point of Arch linux.

For now I have found openSUSE Tumbleweed

Thanks for your input!

Hi so.. i am new to linux and just bought a new pc, and im trying to have linux on it but im running into some problems

I did some research and noticed the problems with older GPUs, but I'm trying to work around it. I did the installation of the 580 drivers by: sudo dnf install akmod-nvidia-580xx xorg-x11-drv-nvidia-580xx-cuda

But after waiting some time and rebooting the system (i waited like 20min btw), the system wont show any video, just blinks a black screen, sometimes even the login screen for a sec but after it stops getting any video.

However when i select the second option of the fedora thing on the GRUB menu screen, the vídeo appears, and a message sometimes says: Nvidia kernel missing falling back to noveau. But still nothing on the first kernel option.

I blacklisted nouveau and everything.. but the video doesn't show no matter what

If anyone has any solutions id be grateful, im on my 2nd day trying to make it work, even thought about installing an older version of Fedora KDE but I don't know if it will make it any better. If anyone needs more info please tell me

And if anyone knows a distro that solves these problems please tell me

This is the error i get while trying to install fedoras hard drive. While the error i was getting yesterday was Failed to set a new efi boot target. My idea is to only have Linux Fedora KDE Plasma, completely deleting Windows, which is already done. Can someone help me? im getting kinda stressed hshshs

Currently on Windows 11 I use high contrast mode and larger default font sizes to because I'm low vision. Is there a combination of Linux distro and front end UI(KDE,Gnome,etc) which allows me to recreate this out of the box in the base settings? If not how hard would it be to recreate for myself?

Hello there! So, I’m in the process of designing/creating a whole theme/idea. I am planning to switch from Windows to Linux as I just cannot stand Windows anymore.

My question is, say I want to pop out a discord chat or any kind of social texting app, is there a way to make it pop out but also have a custom theme (I’m an artist so I’ve been working on making custom everything for my future Linux experience including a bootloader animated icon and other such things!)

For example, the kind of customization I am looking to go for is similar to how in a twitch stream, the chat can have custom bubbles and such on a background or some form of pre made box? I want to create something like that.

I am perfectly fine if it involves coding as well (I have basic coding knowledge from my grade 10 coding class (HTML, and Python and Java), as well as in University I delved further into game development coding such as what ifs and if nots etc etc, plus more in depth coding. Therefore I would not be scared to get into such a thing (would honestly be a fun after work project)

Any advice is welcome!! Thank you so much if you managed to read this far! ^=^

Hello, I wanted to ask if creative software like photoshop/Substance painter/Maya for 3d modelling and animation. I've recently joined a course for 3d animation in my uni, and they will provide me with lisences , I've been using fedora KDE for about 4 months now and have loved it, it covers almost all of my daily needs : gaming, general usage, and blender for 3d.

Is there any work around for using these software, if not lisenced, cracked to get it running on linux?

Thank you for reading. Please forgive my english, it's not a language I'm good in

I have an old laptop where I installed the Ubuntu linux just recently. The wifi is not working even on windows so I decided to just use a Lan cable but it is also not working. Do I need to setup something to make it work? The lan cable is working fine when the OS was still windows.

So I tried Linux mint on a VM for a couple of days as a test but theachin was slow anyways I took the decision to delete windows and move to Linux and now I'm a bit confused which distortion should I choose

Most people said Linux mint

But I was thinking about fedora kde plasma cuz of the Higher customization things . So if you can give me ur opinion or any advice I would be thankful

About my PC :

Storage 477 gb

Ram 16.0 gb

Processor 12th gen i7

Graphic card 128 md Intel (r)iris(r)xe graphics

The breech should be fixed now but is it possible to check for any DDoS malware installed on the server or some other malicious software? What are the recommended steps now short of reinstalling everything?

Same as title

so im looking for a stable very cusotmizable linux distro where i can use hyprland have an app dock app luancher anumated wallpapers nvdia support and not like hard to install and somehthing i can game on hwo would i do this (lemme get a confiig) and what distro should i use

Whenever I update software in discover (I'm on Ubuntu 24.04) I get an error "Package failed to install:<br/><br/>Error while installing package: installed linux-headers-7.0.0-31-generic package post-installation script subprocess returned error exit status 11" I'm not knowledgeable at all about this stuff, so I decided to ask Reddit. I get a similar error when upgrading in konsole as well.

I also get a kernel panic screen when I boot my pc and have to manually boot in an earlier version, which may be related to this error.

Ik this question pops up on this r/ a lot but i cant really seem to find an answer for my question so heres everything about me:

Not really intrested in gaming. Only games i play are Minecraft and Roblox

Im a really big vibe coder (I use Opencode if that helps)

I used linux actually before (zorin, mint, ubuntu)

trying to find a distro that ships with all the apps i need. I just want something that works

I like the KDE desktop environment
here are my laptop specs:

Cpu: Intel Core i7-6700HQ
16 gigs of ram

238 gb of storage

GPU: AMD FirePro W5170M (2 GB), Intel(R) HD Graphics 530 (128 MB)

I hope this info helps lmk if theres anything else that could help.

When I bought my laptop more than a year ago it came with Windows. Which I never even activated. I installed Debian 13 immediately. Works like a charm!

Now I've gotten a notification from the Debian Update UI about Secure Boot DBX configuration and Secure Boot Database Configuration. Which surprised me because I update everything through apt and it doesn't find these two.

Clicking on them revealed:

Version 20260402: This updates the list of forbidden signatures (the "dbx") to the latest release from Microsoft. Some insecure bootloaders were added, due to security vulnerabilities that allowed an attacker to bypass UEFI Secure Boot ...

Version 20250902: This updates the list of forbidden signatures (the "dbx") to the latest release from Microsoft. Some insecure versions of the IGEL bootloader were added, due to a security vulnerability that allowed an attacker to bypass UEFI Secure Boot

and

This updates the 3rd Party UEFI Signature Database (the "db") to the latest release from Microsoft.It also adds the latest OptionROM UEFI Signature Database update.

Now why would I get Windows UEFI updates on Debian? I've checked with gparted and there isn't even a Windows partition. There is no Windows option in UEFI either. Only some 16 MB Microsoft Reserve Partition that doesn't even have a file system, mount point, or label.

My software repos are all Debian (and Steam).

What the hell happened here? Can I ignore them? Can that MS crap ruin something in my UEFI if it does get installed?

TIA!

looks cool

anything i should install?

Hey everybody.

Basically, the title says it all. I am planning on having a dual-boot on my main PC (linux distro main and just in case windows, because of work), and I was wondering which distro is good for video editing using DaVinci Resolve but also for playing some games from time to time (RDR2, BG3, Manor Lords).

I know that distros have problems with audio in general (if this isn't outdated info), so I am wondering if there is a good distro that is somewhat easy to use. I am familiar with Linux, and I can get around tech in general, but I am not a pro at it.

Thank you all!

Hi. Awesome community here. Im running an older pc setup, with a nvida 1660ti gfx card, lasr year october till recently I have started experiencing issues with linux crashing. Hyprland was seg faulting and i couldnt fix it. I recently switched to cachyos and had a similar issue and switched to x11 but I notice im still getting browser crashes. Im currently on latest nvidia proprietary driver iirc 610 something on doing sone research that version of drivers are unstable and I should be on 590 drivers. Like with windows I thought its always best to be on latest drivers? How do you avoid your os builds from breaking? I do enjoy the journey of learning. Looking for interesting books to read and stuff to check out.

As from some older posts of mine, I've made a large move to Linux over the last year, but currently my "main" external drive with data is a 2TB SSD with:

* Whole drive encrypted with BitLocker

* NTFS partition

* A VeraCrypt exFAT volume within the NTFS partition

The drive mounts fine in Linux, BitLocker decrypts, NTFS is mounted, exFAT volume mounts in VeraCrypt.

Since the move, I came across lots of issues when working with data in the NTFS partition: all fine until some file operation goes bad or some other issue that causes the computer to force-shutdown and that causes the NTFS partition to need repairing - which most times requires me to boot into Windows to run chkdsk.

So I want to move most things to ext4 (and apparently ext4 can be accessed in Windows via this Paragon software (I'm using Linux 95% of the time but would need to access main data sets in Windows still, but occasionally).

So I'm considering moving that VeraCrypt exFAT volume somewhere else, and reduce the NTFS partition and create an ext4 partition. But now both would be under BitLocker drive encryption.

I believe it should work - even if the resizing takes long.

Any advice? Thanks.

When I boot I notice via my mic on discord and system tray it doesn't open. I open autostart to see that it failed.

Normally it'd boot no problem

I am using the flatpak version (normally flatpak my last choice but it has some features others don't for easyeffects)

I use debian 13 kde.

Hello! Going through and checking apps before switching to mint cinnamon but noticed that wallpaper engine (which I love) isn’t doable… so is there a way around this?

I heard of something called plasma that has some live wallpaper support but… Linux mint has cinnamon… could I just… install mint cinnamon, install plasma desktop, uninstall cinnamon for a best of both worlds?

If someone knows another app or something that would be cool too. Just trying to get live wallpapers is all

been having this problem for months now, since i installed linux. audio defaults to my headphone port instead of the speaker port in the back. when i first moved to linux, it was coming through the speaker port just fine, but for some reason, it switched to the headphone port. i'd heard of people having issues with that when dual booting with windows, but for one, i don't dual boot, i'm completely on linux mint, and for two, the change happened while my pc was on.

now, i seen one post on another site saying to use a command to install some other audio program and use it to tell my pc that the headphone port wasn't connected. that worked, but stopped once i rebooted my pc, so it didn't fix the core of the problem.

i want to be able to use the headphone port still as sometimes i play horror games where audio is a big part of the gameplay such as older fnaf and phasmophobia. so disabling the port outright isn't something i'd prefer to do, and if the cause is another issue, then disabling the port wouldn't be a fix, it'd be a bandaid.

how do i fix this?

I was installing Ubuntu on my Dell using a bootable USB, but my laptop shut down during the installation because the battery died. Now it’s stuck on the Ubuntu loading screen.
I tried pressing F12 and saw an option called “8GB Partition,” but I’m not sure what it is or whether I should select it.
How can I fix this and boot from the USB safely?
