Silent KLockscreen Port (Plasma 6)

This project is a manual visual port of the beautiful SilentSDDM theme by @uiriansan, specifically modified to work with the native KDE Plasma 6 Lockscreen (kscreenlocker).

Caution

USE AT YOUR OWN RISK. This project modifies critical system files in /usr/share/plasma/. I am not responsible for any broken systems, black screens, or if you get locked out of your desktop. Always ensure you have a terminal (TTY) or SSH access before proceeding. Read the "How to Test" section carefully!

Visual Proof-of-Concept

Original Plasma 6	Ported Silent Look

---

Features & Limitations

• Aesthetic: Ported components (Input, Avatar, Spinner) and typography (RedHatDisplay).
• API Mapping: Adapted SDDM login logic to work with Plasma's Authenticator API.
• Static Layout: Currently supports only the Center Layout. Dynamic positioning (Left/Right) via .conf files is not yet implemented due to Plasma's rigid shell constraints.
• Visual Skin: This is primarily a component-level "skin" over the existing kscreenlocker behavior.

Wallpaper Configuration

Since this is a port for the native Plasma lockscreen, the wallpaper is managed by KDE Plasma's system settings, not the theme's .conf file.

1. Go to System Settings -> Screen Locking.
2. Click Appearance (Configure...).
3. Select your preferred wallpaper.

Using Video Wallpapers (Recommended)

To achieve the animated background look (MP4/WebM) as seen in some SilentSDDM previews:

• I use the "Smart Video Wallpaper Reborn" plugin.
• You can install it via the "Get New Plugins" button in the Wallpaper configuration window.
• It works perfectly with this ported layout!

Installation

1. Clone this repository:

   git clone https://github.com/Khip01/Silent-KLockscreen.git
   cd Silent-KLockscreen

2. Run the installer: The script will automatically create a backup of your original lockscreen files at /usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen.bak.

   chmod +x install.sh
   ./install.sh

---

How to Test Safely (DO THIS FIRST!)

DO NOT press Meta+L immediately after installation. Run the following command to see a preview of the lockscreen in a window:

/usr/lib64/libexec/kscreenlocker_greet --testing

Note

The path might vary by distribution. If not found, try searching for the kscreenlocker_greet binary.

If the window opens and looks correct, you are safe to lock your screen (Press Meta+L). If it crashes or shows a "broken QML" message, run the recovery script immediately.

---

Recovery

If something goes wrong or you want to go back to the default Plasma look:

chmod +x uninstall.sh
./uninstall.sh

Credits

• Original Artwork & Design: All credit goes to uiriansan, the creator of SilentSDDM.
• Porting: Ported to Plasma 6 by Khip01/me to bridge the visual gap between SDDM and the KDE Lockscreen.
• License: Distributed under the same license as the original project (GPL-3.0).

---

Technical Details (For Developers)

• Target Path: /usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen
• Logic: Replaced sddm.login() with authenticator.respond(password).
• Styling: Uses a SilentConfig.qml singleton to manage theme variables without a native SDDM theme engine.
