Compton与KDE Plasma如何集成

Installing Compton
To integrate Compton with KDE Plasma, start by installing Compton on your system. Use your distribution’s package manager (e.g., apt for Debian/Ubuntu) to install the package:

sudo apt update && sudo apt install compton

This ensures you have the latest version of Compton available for configuration.

Configuring Compton for Compatibility
Compton’s behavior is controlled by a configuration file (typically ~/.config/compton.conf). Create or edit this file to optimize performance and compatibility with KDE Plasma. A basic configuration example includes:

# Disable desktop background to reduce resource usage
background none
# Enable window shadows for a polished look
shadow true
# Set shadow opacity (0.0-1.0) and radius (pixels)
shadow-opacity 0.5
shadow-radius 4
# Enable fading effects for window open/close/minimize
fade true
fade-delta 30
# Use OpenGL backend for better performance (if supported)
backend glx
# Exclude certain windows from shadows (e.g., docks, panels)
shadow-exclude = [".*Dock", ".*Panel"]

Adjust these settings based on your hardware (e.g., disable glx if you experience glitches) and preferences.

Setting Compton as the Window Compositor in KDE Plasma
KDE Plasma allows you to manually select a window compositor. To use Compton:

1. Open System Settings (e.g., via the application menu).
2. Navigate to Workspace Behavior > Window Management > Window Compositor.
3. In the “Window Compositor” dropdown, select Compton from the list.
4. Click Apply to save the changes.
   This tells KDE Plasma to use Compton for window animations, transparency, and effects.

Enabling Compton at Startup
To ensure Compton runs automatically when you log in to KDE Plasma, add it to your startup applications:

1. Open System Settings > Startup and Shutdown > Autostart.
2. Click Add Program (or Add Script).
3. Enter the command to start Compton with your custom configuration:

   compton --config ~/.config/compton.conf
   

4. Click OK to save the entry.
   This ensures Compton launches every time you start your session.

Troubleshooting Common Issues

• Performance Problems: If you experience lag, try reducing the frame rate (add frame-rate 30 to your config) or switch to the xrender backend (set backend xrender)—these changes can improve performance on older hardware.
• Window Glitches: Ensure your graphics drivers are up to date. For NVIDIA/AMD GPUs, install proprietary drivers to avoid compatibility issues.
• KDE Plasma Version Conflicts: Newer versions of KDE Plasma (e.g., 6.x) may prioritize Wayland over X11. Compton works best with X11—if you’re using Wayland, consider using a Wayland-compatible compositor like KWin (built into KDE Plasma) instead.
