Setup 42 Fedora KDE Plasma

This guide is mainly written for Linux newcomers, but if you're already experienced with Linux distros, feel free to skim through and pick what you need. I've tried to make this as comprehensive as possible while keeping things beginner-friendly.

Getting Started

Download & Verification

First things first - let's get Fedora 42 KDE downloaded safely:

Download Options:

• Direct download: Official Fedora KDE Site
• Torrent (usually faster): Fedora Torrent Site

Verification (Don't skip this!): Look, I know verification seems tedious, but trust me - one corrupted download and you'll be scratching your head for hours wondering why things aren't working right.

1. Download the checksum file the same folder as your ISO

2. Import Fedora's GPG key:

   curl -O https://fedoraproject.org/fedora.gpg

   (You can verify key details here)

3. Verify the checksum file:

   gpgv --keyring ./fedora.gpg Fedora-KDE-42-1.1-x86_64-CHECKSUM

4. Check if your ISO matches:

   sha256sum --ignore-missing -c Fedora-KDE-42-1.1-x86_64-CHECKSUM

If everything checks out as "OK" or "valid", you're good to go!

Creating Bootable Media

Grab a USB drive with at least 4GB space and use the official Fedora Media Writer. It's reliable and handles everything automatically.

Post-Install Setup

Firmware Updates

⚠️ Important Note

If your laptop can update firmware without needing Windows, definitely look into this. It's one of those small things that makes your life easier down the road.

Before updating to new firmware, check the discussion forums or blogs related to your specific laptop model.
If other users report that the firmware update works without issues, it’s generally safe to proceed.
BIOS updates are especially critical, so exercise extra caution.
Make sure to research thoroughly online before installing any firmware updates.

sudo dnf install fwupd
sudo fwupdmgr refresh
fwupdmgr get-devices
fwupdmgr get-updates
sudo fwupdmgr update

Be careful with that last command! Use the other commands first to see what's available, cross-check with your vendor's official site, and check forums for any reported issues.

Network Configuration

I set up a static IP for my laptop on my home router using its MAC address. Fedora randomizes MAC addresses by default (good for privacy), but I needed consistency since my Nextcloud server only accepts connections from specific IPs.

Here's how to use your real MAC address:

1. Click on your WiFi network, then Configure
2. Go to Wi-Fi tab, find Restrict to device section
3. Click the dropdown - you'll see your system's hardware MAC address
4. Copy that MAC address
5. Paste it in the Cloned MAC Address field
6. Hit Apply and reconnect to WiFi

Custom DNS Setup: While you're there, might as well set up custom DNS:

1. Go to IPv4 and IPv6 tabs
2. Under Method, choose Only addresses
3. In the DNS servers section, add your preferred DNS

I use Google's DNS, but test a few options (Google, Cloudflare, your ISP) and see which works best for your location:

Google DNS:
8.8.8.8, 8.8.4.4 (IPv4)
2001:4860:4860::8888, 2001:4860:4860::8844 (IPv6)

Cloudflare DNS:
1.1.1.1, 1.0.0.1 (IPv4)
2606:4700:4700::1111, 2606:4700:4700::1001 (IPv6)

DNF Package Manager Tweaks

Let's speed up package downloads:

sudo nano /etc/dnf/dnf.conf

Add these lines under [main]:

max_parallel_downloads=10
fastestmirror=1

Press Ctrl + X, then Y, then Enter to save.

Initial System Setup

If you didn't set a hostname during installation, do it now:

sudo hostnamectl set-hostname <your-hostname>

First System Update: For your very first update, I actually recommend using the Discover software center. Yeah, it's slower, but it's more stable and handles any hiccups better than the command line for that crucial first update.

You can always use the faster command later:

sudo dnf upgrade

Note: Don't enable third-party repositories yet - wait until after your first update and reboot.

Adding Repositories

After your first update and reboot, let's add the good stuff:

Enable Third-Party Repos via GUI: Open Discover Software Center → Settings and check:

• RPM Fusion for Fedora 42 - NonFree - NVIDIA Driver
• NonFree - Steam

Command Line Method:

sudo dnf config-manager setopt fedora-cisco-openh264.enabled=1

sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \
https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

sudo dnf install rpmfusion-*-appstream-data

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

Caution: If you're having graphics driver issues with RPM Fusion, stick to Fedora's repositories for now. You can add Flatpak support separately.

Graphics & Hardware

Kernel & Build Tools

Install the essentials for building drivers and modules:

sudo dnf install kernel-headers kernel-devel-matched
sudo dnf install kernel-headers kernel-devel tar bzip2 make automake gcc gcc-c++ pciutils elfutils-libelf-devel libglvnd-opengl libglvnd-glx libglvnd-devel acpid pkgconfig dkms

AMD Graphics Setup

Good news for AMD users - the open-source drivers are excellent and included by default!

Install hardware acceleration:

sudo dnf install mesa-va-drivers mesa-vdpau-drivers libva-utils vdpauinfo

Verify everything's working:

vainfo
vdpauinfo

AMD GPU monitoring (like nvidia-smi for AMD):

sudo dnf install amdsmi

For full hardware video decoding, swap to the "freeworld" versions from RPM Fusion:

sudo dnf swap mesa-va-drivers mesa-va-drivers-freeworld 
sudo dnf swap mesa-vdpau-drivers mesa-vdpau-drivers-freeworld

These freeworld packages unlock additional codecs and acceleration features that are crucial for AMD hardware.

Important: Don't mix standard and freeworld versions - it'll cause conflicts during updates. If you're having issues with AMD graphics, stick with the standard Fedora repository versions.

Check RPM Fusion's documentation for more details.

Reboot after installing AMD drivers.

NVIDIA Graphics Setup

NVIDIA is trickier. You have two main options:

Option 1: RPM Fusion (Recommended for most users)

⚠️ Pro Tip: Don't just blindly upgrade drivers. Check versions first - only install if it's actually newer than what you have.

sudo dnf install akmod-nvidia

Don't reboot yet! Wait for the drivers to compile:

modinfo -F version nvidia

If you don't see a version number, wait up to 5 minutes and try again. Only reboot once you see the NVIDIA driver version.

Option 2: Official NVIDIA Repository

If RPM Fusion drivers give you trouble, try the official repo. As of writing, there's no Fedora 42 repo yet, but Fedora 41's works fine:

wget https://developer.download.nvidia.com/compute/cuda/repos/fedora41/x86_64/cuda-fedora41.repo
sudo dnf config-manager addrepo --from-repofile=./cuda-fedora41.repo
sudo dnf install kmod-nvidia-latest-dkms nvidia-driver nvidia-driver-cuda nvidia-driver-libs nvidia-driver-cuda-libs nvidia-settings --allowerasing

Same deal - verify the driver loaded before rebooting:

modinfo -F version nvidia

After reboot, install hardware acceleration:

sudo dnf install nvidia-vaapi-driver libva-utils vdpauinfo xorg-x11-nvidia

User Permissions

Add yourself to the right groups for GPU access:

sudo usermod -aG render,video $USER

Log out and back in (or reboot) for this to take effect.

Hybrid Graphics & PRIME

Got a laptop with both integrated and discrete graphics? Let's set that up properly.

BIOS Settings:

• Disable Secure Boot
• Enable Switchable Graphics

Check your setup:

/sbin/lspci | grep -e VGA
/sbin/lspci | grep -e 3D

If your NVIDIA card shows up in the second command, you're in hybrid mode.

Verify with:

switcherooctl

You should see something like:

Device: 0
  Name:        AMD Cezanne [Radeon Vega Series]
  Default:     yes
  Environment: DRI_PRIME=pci-0000_05_00_0

Device: 1
  Name:        NVIDIA Corporation TU117M [GeForce GTX 1650]
  Default:     no
  Environment: __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only

That Default: no confirms hybrid mode is working.

Install EnvyControl for easy switching:

sudo dnf copr enable sunwire/envycontrol
sudo dnf install python3-envycontrol

KDE Widget:

Add the "Optimus GPU Switcher" widget to your panel for easy GPU switching.

GPU Application Offload

Command line method (NVIDIA):

env __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only <your_application>

# Or the simpler way:
switcherooctl launch -g 1 <your_application>

KDE GUI method:

1. Find the app's .desktop file in /usr/share/applications/ or ~/.local/share/applications/
2. Right-click the application → Properties → Application tab
3. Advanced Options → Check "Run using dedicated graphics card"

This creates a local .desktop file in ~/local/share/applications/ that always runs the app on your discrete GPU.

Customization & Extras

KDE Customization

Time to make KDE look awesome! First, install build dependencies:

sudo dnf install git cmake extra-cmake-modules gcc-g++ \
kf6-kwindowsystem-devel plasma-workspace-devel libplasma-devel \
qt6-qtbase-private-devel qt6-qtbase-devel kwin-devel \
kf6-knotifications-devel kf6-kio-devel kf6-kcrash-devel \
kf6-ki18n-devel kf6-kguiaddons-devel libepoxy-devel \
kf6-kglobalaccel-devel kf6-kcmutils-devel kf6-kconfigwidgets-devel \
kf6-kdeclarative-devel kdecoration-devel wayland-devel \
libX11-devel libXext-devel qt6-qttools-devel qt6-qtsvg-devel

Better Blur Effect:

git clone https://github.com/taj-ny/kwin-effects-forceblur.git
cd kwin-effects-forceblur
mkdir build && cd build
cmake ../ -DCMAKE_INSTALL_PREFIX=/usr
make -j
sudo make install

Kvantum Theme Engine:

Method 1 (latest version):

# Download latest tar.xz from https://github.com/tsujan/Kvantum/releases
# Example for version 1.1.5:
tar -xf Kvantum-1.1.5.tar.xz
cd Kvantum-1.1.5
cd Kvantum
mkdir build
cd build
cmake ..
sudo make install

Method 2 (easier but older):

sudo dnf install kvantum

System Utilities & CPU Control

Auto CPU Frequency Management:

git clone https://github.com/AdnanHodzic/auto-cpufreq.git
cd auto-cpufreq
sudo ./auto-cpufreq-installer
sudo auto-cpufreq --install

This tool dynamically manages your CPU frequency based on usage - great for laptop battery life! I’ve included a config file — tweak it however you like.

Multimedia & System Settings

KDE System Settings modules:

sudo dnf install plymouth-kcm kcm_systemd flatpak-kcm sddm-kcm
sudo dnf install cronie cronie-anacron kcron 

Multimedia codecs:

sudo dnf group install multimedia

Font rendering tip: Go to System Settings → Appearance → Fonts, enable Sub-pixel rendering (RGB) and set Hinting to Medium (or adjust to your preference).

Plymouth Boot Splash

Speed up boot by disabling a slow service:

sudo systemctl disable NetworkManager-wait-online.service

Change boot splash theme:

# List available themes
plymouth-set-default-theme --list

# Set your preferred theme
sudo plymouth-set-default-theme -R <theme-name>
sudo dracut -f

Disabling Unwanted Services

Calender Notification and Discover autostart at boot and use additional RAM. To disable them:

1. Find the .desktop file in /etc/xdg/autostart/ or ~/.config/autostart/
2. Open it with a text editor
3. Add Hidden=true after the [Desktop Entry] line and comment out the lines related to autostart phase.
4. Save the file

This prevents the application from autostarting without completely removing it.

Adding Custom Gestures on Fedora

Setting up custom touchpad gestures on Fedora is actually pretty straightforward — thanks to libinput, which Fedora uses by default.

🛠️ First, install the necessary tools:

If you're using Wayland, run:

sudo dnf install xdotool wmctrl ydotool

If you're on X11, then you only need:

sudo dnf install xdotool wmctrl

👤 Add yourself to the input group:

sudo gpasswd -a $USER input

📦 Install libinput-gestures

You can check out the official GitHub page, but here's the quick and easy version:

git clone https://github.com/bulletmark/libinput-gestures.git
cd libinput-gestures
sudo ./libinput-gestures-setup install

Once that's done, go ahead and reboot your system — just to make sure everything loads cleanly.

---

✨ Now for the fun part — custom gestures!

If you want to see live gesture input for debugging or experimenting, run:

sudo libinput debug-events

To create your own gestures, you’ll mostly be using xdotool (and ydotool if xdotool does not work on Wayland, and that's a big if, as it works using xwayland). You can explore their documentation if you want more complex setups:

• xdotool reference or just run man xdotool

• man ydotool for that one too

---

📸 Let's make a gesture that takes a screenshot

Normally, pressing the PrtSc key takes a screenshot. You can do the same through the terminal like this:

xdotool key Print

⚠️ On Wayland, a permission popup might appear. Sadly, it won’t remember your choice after a reboot — known issue. But X11 handles this fine and remembers.

Once that works in your terminal, we can turn it into a gesture.

---

📝 Create your gesture config file:

nvim ~/.config/libinput-gestures.conf

Add this simple line:

gesture hold on 3 xdotool key Print

This means: hold three fingers on the touchpad and it’ll trigger the PrintScreen key.

---

🚀 Make it start on login:

libinput-gestures-setup autostart
libinput-gestures-setup stop desktop autostart start

If it says libinput failed to start, just reboot your system, then run that command again.

---

✅ Time to test!

Place three fingers on the touchpad, hold for 2 seconds, then lift. You should see a screenshot happen — just like magic ✨

---

🛑 To stop the gestures:

libinput-gestures-setup stop

❌ And to stop it from auto-starting:

libinput-gestures-setup autostop

---

Happy tweaking! Make it yours. You can keep adding more gestures — sky’s the limit 🌟
