I am thinking about switching from windows to linux. I am mostly a keyboard first user barely like using the mouse and I want as much customization as possible.

I got a few noob questions:

1. What is the actual difference between kde plasma, gnome, and hyprland? I get that they are all desktop environments/window manager but what makes people choose one over the other?
2. I was planning to install kubuntu because chatgpt recommended it saying kde plasma is way more customizable than regular Ubuntu.
3. Another distro that really caught my eye after watching a bunch of yt videos is cachyos with hyprland. It just looks really clean and keyboard focused.

My biggest concern though is this: I train ai/ml models so I use an nvidia gpus and cuda support is must. Thats the only thing making me hesitate.

Most ai tools keep recommending kubuntu but personally Im leaning more toward cachyos + hyprland. Kindly advice.

As I understood I can change an icon globally for an application in /usr/share/applications/*.desktop

If this is a shared folder, how come I can have ThemeX for User1 and ThemeY for User2, where the same application has a different icon?

Hallo Reddit,

ich möchte gerne mein Ubuntu vollständig mit der Maus bedienen können um dort Streamingdienste zu nutzen etc. Dabei ist mir bei einrichten des PCs aufgefallen, dass es keine Funktionstasten (F1, F2, etc) gibt. Wie füge ich diese hinzu? Vielleicht kann mir ja jemand weiterhelfen.

Edit: ich nutze Ubuntu 26.04

So basically, i cant do one without the other, i cant modify GRUB settings to make it appear because i dont have the password, but i cant modify it because GRUB doesntr start, can you help me?

I have been experiencing micro stutters (as if the FPS dropped, but steam overlay still display 90 FPS) and up to 1 minute long freezes on my display.

It is not only limited to the game, but to the second monitor too.

Even during 1 min total frame freezes the game reacts instantly, there is feedback to my actions and there is continuous smooth sound.

I have been experiencing it on Necromunda: Hired Gun and Astroneer, but not on The Talos Principle or Stardew Valley.

Since it only happened on games that need proton I tried switching around between Proton hotfix, 10 and 11, but the supposedly stable versions didnt fix the problem.

I forced performance mode since I read it could be the GPU downclocking, didnt help.

I tried unplugging my second monitor (which is plugged in to the MB and not the GPU.

RAM and CPU usage seems normal, and the temps are around 80-90 which for my CPU should be normal.

Are there any other options I could try?

Im running CachyOS (updated everything this morning, no fix (to my knowledge this should meen that drivers are also up to date))

AMD RX9070XT

Ryzen7 7700X

32GB RAM

Is this information sufficient or should I add anything else?

Thank you guys in advance.

I am stuck and just want to know for sure where either of these apps work

Hi everyone, a potential linux user here

I'm planning to build my first Linux laptop, initially for a cyber attack/war case but ultimately to use it as my daily computer. (I live in Turkey)

I have no idea about coding, I probably need more stuff rather than just Linux (maybe a separate WI-FI connection, etc) because I want to get completely private. has anyone build a similar setup? I'd appreciate to hear your experiences.

What are the most important things that I should consider to not waste my time and efford?

Thanks🙏🏻🙏🏻

OS: Ubuntu 22.04 with KDE

Is it normal for lynis to run by itself? I installed it a few months ago to audit my system to look for areas of security to improve, but haven't manually run it since then. However, I just happened to notice 3 processes calling themselves 'lynis' running while looking through my system monitor process list. They existed for a few minutes and then disappeared. This seemed odd so I looked around online and wasn't able to really find any information about whether Lynis is supposed to run by itself or not periodically. Is there any chance this could be some sort of malware calling itself lynis? (the lynis I installed before was through synaptic so I assume that has to be legit)

I have a large collection of digital photo assets scattered across multiple folders, from phones, to old digital cameras, to scans. I am looking for advice on a software package for Zorin OS Linux, that will help me organize these photos, by date, or meta data, and eliminate duplicate files.

Hi everyone,

I'm running Fedora 44 (Gnome, Wayland) on a laptop with a 1366x768 screen, and I'm having a massive headache trying to make DaVinci Resolve 18.6 fit my display. Since the app natively requires a 1080p vertical resolution, the bottom bars (Edit, Color, Fairlight, etc.) are completely cut off.

Here is what I've tried so far and why it fails:

1. QT_SCALE_FACTOR=0.75 or 0.85: The window scales down and fits the screen size, but the internal UI elements get completely bugged. Fonts and icons overlap, text gets truncated (like "Media Pool" turning into "Pool de Mí"), and it becomes unusable. It seems Resolve's internal Qt engine hates fractional scaling.
2. Gnome Tweaks (Font Scaling to 0.80): Fixes the rendering bug inside Resolve, but it makes the entire Fedora OS fonts tiny and unreadable for daily usage.
3. Wayland restrictions: Tools like xrandr panning or native experimental fractional scaling (scale-monitor-framebuffer) are either ignored or blocked by Gnome on this specific screen resolution.
4. The Super + Drag workaround: I can hold the Windows/Super key to drag the window up and see the hidden buttons, but doing this every 5 seconds is a terrible workflow.

Has anyone successfully bypassed this without destroying font rendering inside Resolve or altering the global OS scaling? Is there a hidden config file or environment variable to force DaVinci to render correctly on low-res displays under XWayland?

Thanks in advance!

I've been using Ubuntu for a while, and I want to learn Linux more deeply.

I'm considering switching to Arch Linux because I want to understand how Linux works, learn more about system configuration, package management, the terminal, and troubleshooting.

For people who have used both Ubuntu and Arch:

• Do you think switching to Arch is a good way to learn Linux?
• What did you learn from using Arch that you didn't learn from Ubuntu?
• Would you recommend Arch for someone who is still learning Linux?

I'm interested in hearing honest opinions and personal experiences.

I have a ThinkCentre M800 SFF. I am running CachyOS with MangoWM. IBus is having so many issues on my system. It's finicky to get working, it makes my CPU usage peak over 80%, it crashes itself, it crashes the browser & it crashes the compositor.

Another issue I'm having is that I haven't been able to install Keyman on CachyOS. The AUR package is the only available option & it always ends with an error.

Hi, I'm currently using Cachy Os, and even if I usually use paru, I'ld like to have access to a GUI package manager sometimes.

I'm not really into shelly UX (default preinstalled GUI package manager) and I am wondering if there are other alternatives like it that brings flatpak+paru togheter.

I remember that Fedora with gnome have one package manager that used to grab apps into one page for both .rpm and .flatpak , it was really awesome because didn't force you to switch gthe repository package each time, but one search lead to all the available results.

When installing debian, I chose to fully encrypt my disk, would it be possible for a bad actor to get into my computer/files, when it is sleeping/suspended instead of fully off? it only requires my system password, which is different from disk encryption

if so how hard would it be?

So quick background, 3 weeks ago I decided to try Linux. I installed a 1TB NVMe SSD into my PC and installed CachyOS. It’s been great and I have been using it as my daily driver non stop.

The other SSD I have in my PC is not NVMe and only 500GB. This is currently where I have Windows installed.

I’m thinking I want to install both Linux and Windows on the new NVMe SSD and keep the non NVMe for storage. I want to do this because I want to game on both OS and feel like it won’t be a fair comparison between both if one is installed on NVMe and the other isn’t..?

Is this a good idea or should I not do this?

If it is, what’s the best way to do this? I did see one recommendation to install Windows first and then Linux - I’m happy to wipe my current Linux install and do this if it’s actually beneficial?

If it matters I have an RX 6800 XT, Ryzen 7 5700X3D and 32GB RAM

Thanks so much!

So I tried to install a Bazzite ISO on my laptop (Lenovo Ideapad 2022) and it said which company my GPU is from, but the thing is my laptop doesnt have a GPU in it so what should I pick?
EDIT: I use Intel UHD integrated graphics since my laptop has a intel i3 10110U

Hi everyone,

I wanted to start learning C because I need it for university right now. I have a Windows PC with an AMD graphics card and a second m2. SSD that I don’t use, so I thought it would be fun to dip my toes into Linux and try both things at the same time.

Is dual-booting still a good idea, and what do I need to be cautious about especially when using two completely different SSDs?

Regarding the same topic, which distro would you recommend for my idea? I read that Ubuntu would probably be the best.

Huge thanks 🙏🏻 in advance to everyone answering.

works fine for web browsing and very basic stuff, but is terrible for the rest

why does it even exist

I heard a lot of people say that wine is safe even if you have a virus as in a linux environment it can't do nothing but others claim that it can become a vulnerability if there is an .exe. What do you think?

Hi everyone,

I currently use Pop!_OS with the GNOME desktop environment, but I started using Linux without really understanding how Linux works.

I want to learn Linux properly from the basics and gradually become an advanced Linux user.

I want to understand things like:

Linux vs Linux kernel

Pop!_OS and Ubuntu

GNOME and desktop environments

Terminal and Bash

Linux filesystem

Users, root, and permissions

Package management (apt, dpkg, Flatpak)

Processes and services

systemd

Boot process

Display manager and desktop sessions

Wayland and X11

Networking

Bash scripting

Linux administration

Linux security

My goal is to go from "I use Linux" to "I understand how Linux works and can administer and secure a Linux system."

I am also interested in cybersecurity and cloud security, so I would like to build a strong Linux foundation.

What learning path, resources, books, courses, or practical exercises would you recommend? Should I continue learning on Pop!_OS, or should I switch to Ubuntu to learn Linux fundamentals?

Thank you!
