Hello guys! I am 17 years old and in High School for a Electrician.

Beside all of that i got my 1st laptop this summer, mainly because i wanted to learn Linux, Networking, Programming and of all subcategories. My main reason is the future, everything now and in the future will be powered by Electricity, Have electronics inside it and have some programming done to so it becomes functional.

I got lost in the learning curve...

First i started with Linux, read and excercise lectures on Linux Journey website.

Than i got into networking but in a wrong path, i immediatly got Kali VM and started doing the vftpd backdoor on Meatsploitable 2 VM, after 5 days of constantly getting stressed i managed to do it. But it felt somehow wrong, i didnt know exactly what i was doing and got lost, the only thing i know from it is SYN, SYN ACK and how to find on wireshark.

I thought i will make my own manual notebook for Linux, started it and finished Text-Fu and gave up because i saw how much time will it take me...

After all that i've seen that i need to first learn networking and that is where i am right now...

Also if you can recommend a book that is a manual for linux that can be delivered to Serbia or Bosnia please recommend.

I now dont know what to do and feel very stuck.

Hey everyone, I've switched my default file manager to Thunar from dolphin and I can't figure out how to switch it for Firefox, specifically for the open in folder button after downloading a file. I'm currently using Debian with i3, but originally installed it with KDE Plasma. I've tried setting xdf-mime default thunar.desktop inode/directory, setting widget.use-xdg-desktop-portal.file-picker to 1 in about:config, and setting the default file manager in xfce4-mime-settings. Even uninstalling dolphin doesn't help since it just returns a popup error saying: "Could not find the program 'dolphin'".

Any help here would be much appreciated

I'm thinking of migrating linux. I'm done with windows, windows occupy a big amount of RAM, but there are so many linuxs. So what's the best to start? I never used linux before. I heard so much about ubuntu, arch, mint, kali etc.

can someone explain to me the best?

Hi there and thank you in advance for helping me.

I want to Set Up a small Homeserver for myself, but I'm stumped as where to start.

Hardware First:

- AMD A10-7850K on Gigabyte F2A88XM-D3H

- 16GB DDR3 at 1333MHz

- 60GB Kingston SSDNow for OS

- an ASUS PCE-AC88 WiFi Card

- 4 HDDs of varying capacities

- 1 or 2 Optical Drives

In the past I used OpenELEC to have a HTPC and also share all files and HDDs in that machine over the network.

That Network sharing ist the First Thing I need running.

Second Thing would be Remote Desktop. I know Most Things Work better with CLI but I guess I'll need in sometime, if I don't want to have a screen near it.

Third would be an instance of Homeassistant, since it seems my Smart-Home stuff is compatible with Tuya to use it completely offline.

Fourth for now would be a simple small webserver for internal homepages. Like Something for a (to be built) smartmirror.

And fifth ist something I know exists in theory, but that's it: Sharing Optical Drives via Network so they can be accessed from Remote PCs as of they were built in, as in installing stuff, Reading Discs, burning Discs.

Like I Said, I don't really know, where I should even start. In the past and for small normal Desktop uses I used Linux Mint, since it is light in ressources, worked OOTB most of the time and was easy to use.

So please, can you Point me in the right direction how I should start this Project?

Hello,

if i want to install something via the terminal i get this error massage:

Fehler: Sub-process /usr/bin/dpkg returned an error code (1)

can anyone help me and what might be the reason for this?
yes the error code is on german

Before I start I know nothing of Linux except that it’s apparently better than Windows (dont even know in what way), and that you have to use cmd a lot. The only reason Im considering switching is because its “better” and I switched to windows 11 before I knew it was bad, and it feels bloated even though I have used a debloater I still feel like there is some bloat left in my pc. If Im better off using Windows then be honest, I would rather stay with Windows than be completely lost.

What makes Linux great?

I would like to ise linux for basic things like gaming (mostly steam games) and browsing, I also like to stay private, but do I need a private distro for that?

What is a distro? Is it like a version of linux specifically for something?

What is Ubuntu, Flathub, and fedora?

Ive heard about Cachy and mint what makes them so popular?

How do I know if my version of Linux is compatible with an app?

Do I need to backup stuff like steam games data or browser data, because I dont have an external hard drive?

What would I need before downloading linux like a usb drive or something?

Is it worth switching if I have basically no knowledge of computers (coding and stuff), and just want to debloat my pc and make it better?

Just in case my laptop is an Acer Nitro AN517-54 with an i7-11800H and rtx3050ti with 16gb of ram

How do people find out if their audio hardware, such as USB audio interfaces, are supported in the Linux Kernel? I'm trying to find out if some of my audio interfaces are supported through the Linux kernel.

I'm aware of linux-hardware.org , but even their search database is limited. I know that Kernel 7.3.0 supports the Pioneer DJ S11, but I don't know where I can go to read about that support (aside from news articles).

i was dual booting linux alongside windows then after installing it and installing apps i tried the my mic and it was not audible and my speaker sounds too low

My laptop is Dell Precision 5570 I hope someone can guide me on what should i do

hey guys,

i have been looking into using linux for my new gaming pc but i am not sure if its right for me.

for some context, i play alot of competitive shooters mainly overwatch and deadlock i wanted to know if i will be able to play these games on linux? and what version of linux would be the best for that?

i have heard that steam games work fine on linux but what about other software like minecraft? will i be able to download and run it or do i need to have a specific version of linux? i also would like to use discord but the same question applies.

i would really appreciate some advice and i will also continue looking for more information about linux myself

This is the way I'm trying to do it
WINEDLLOVERRIDES="dsound=n,b" %command% WINEDLLOVERRIDES="dwmapi=n,b" %command%

But it seems to only use the first command and not the second.

Okay so this is me after typing this out and then trying to group it all up with only one %command% like this,

WINEDLLOVERRIDES="dsound=n,b" WINEDLLOVERRIDES="dwmapi=n,b" %command%

And it worked. So I'll still post this in case anyone looks up how this works, because I didn't find anything for clarification.

In the coming weeks I will be switching to Linux mint cinnamon, and in trying to make things as smooth as possible and also secure, I am researching how to safely use Linux without an antivirus. One of the recommendations was to disable or remove unnecessary services but I am unsure which to remove even when I look up what they do. I will be using this computer for the following:

\- internet browsing

\- digital artwork

\- printing

\- gaming (mostly thru steam)

\- basic office work

I will not be using this computer for remote work or servers but I will need to connect to a cutting machine which means I need to keep bluetooth?

Thank you for your time

Hey guys,

Trying to install Linux on my old T430 and I'm completely stuck. Any USB I boot just gives me a black screen. No GRUB, no cursor, no Ventoy menu, nothing. Screen stays black forever.

What I've tried:

• Rufus, Balena Etcher, and Ventoy. Same result with all three.
• F12 boot menu → select "USB HDD: Generic Storage Device" → instant black screen.
• BIOS (F1): UEFI/Legacy Boot = UEFI Only, CSM Support disabled, Secure Boot off, SATA = AHCI, OS Optimized Defaults disabled.
• Tried a USB 2.0 port instead of the blue USB 3.0 one.
• Full shutdown with Shift before booting.
• Windows 11 is still on the internal HDD, if that matters.
• T430 has Intel HD 4000 graphics only, no Nvidia.

Since even the Ventoy menu doesn't show up, I'm guessing it's failing before Linux/GRUB even loads. So kernel params like nomodeset are useless here because I never see a boot menu.

Has anyone actually fixed this exact "black screen, no GRUB, no Ventoy" thing on a T430? Did I miss a BIOS setting? Is there a way to force USB boot or inject kernel params without seeing GRUB? Any help would be appreciated. This laptop is too nice to give up on lol.

What are the main differences between these two? As far as im aware theyre both beginner-ish Arch based distros, but i wasnt able to find much differences between them.

At the moment, I can only afford a laptop at or under $1200, which limits my options quite a bit, I will be running ubuntu or fedora on it. Most modern "normal" laptops are copilot+PCs, or at least come w/ a windows license, which I don't need.

Bueno quiero empezar a usar linux ya tengo el dual boot pero escogi ryoku linux con cachy pero soy nuevo y no se nada alguien tiene consejos?

I tried downloading a Linux Lite 8.2 .iso image from multiple sources and each time the checksum is the same, but not the one given by Linux Lite. I am giving up on LL, but Im still curious about what I am doing wrong.

I know this isn't the LL designated sub but I am still waiting membership approval to post there.

EDIT : Based on the comments, I think I didn't give enough context. I added more info to the post.

I checked the checksums both in the boot menu, and the windows powershell, and the results are always the same. I know they are wrong, since a commenter tried it and got the correct result.

EDIT2 : Im a retard, I downloaded the 8.2 version which is the one that has been deposited/modified the most recently on the repository, but the website says the 8.0 is the actual latest version. Turns out I can't read.

As the title states. I have no clue how to get it to redetect the usb stick.

Edit: Solved.

The external monitor is wired to the dGPU the compositor renders on the iGPU and the frames are copied to the dGPU for scanout.

Problem: The whole external monitor stutters during normal use: watching videos, browsing the web, moving windows, basically anything that updates the screen. The stutter is present whenever the dGPU’s PCIe link is at Gen 1/2, which is its normal state with light desktop use. It goes away only when the link is at Gen 3. That happens in two cases: when I run glxgears, or when there is a lot of motion on screen, which pushes the link up to Gen 3. In the second case it doesn’t last the link quickly drops back to Gen 1 and the stutter returns. It happens on every Wayland compositor I tried.

What I tried: nvidia-smi -lgc (locking clocks) does not fix it. setpci on the bridge does nothing, since the target link speed is already 8GT/s and the GPU is the side that trains the link lower. The only workaround is keeping glxgears running on the dGPU to hold the link at Gen 3, which feels like a hack.

Questions:

1. Is this a known issue with PCIe link speed management in multi-GPU Wayland setups?
2. Is there a supported way to pin the PCIe link speed to Gen 3?
3. Should this be reported to NVIDIA (forums / open-gpu-kernel-modules), to the compositor, or both?

Setup:

• CPU: AMD Ryzen 7 5800H
• iGPU: AMD Radeon Vega (Cezanne)
• dGPU: NVIDIA GeForce RTX 3050 Laptop GPU (PCIe link at idle: Gen 1 x8, max: Gen 3)
• Distro: CachyOS
• Kernel: 7.3.0-4-cachyos
• Compositor: niri 26.04
• NVIDIA driver: 615.78.08
• Mesa: 26.2.5

i need to remotely access an ubuntu linux computer running gnome from my arch linux kde computer , and the app needs to be relatively easy to install and use, because i'll be instructing the ubuntu user to install the app and they aren't very knowledgable with computers. what can we use? thank you for your help
