Compton与Wayland怎样搭配

Installing ComptonCompton can be installed using your distribution’s package manager. For Debian/Ubuntu-based systems, run:

sudo apt update && sudo apt install compton

For Arch-based systems (e.g., Manjaro), use:

sudo pacman -S compton

This installs the latest version of Compton compatible with your system.

Configuring Compton for WaylandCompton’s configuration file is typically located at ~/.config/compton.conf (create it if it doesn’t exist). To enable Wayland support, add or modify the following key:

backend = "wayland";

Additional optimizations (optional but recommended) include enabling shadows (with exclusions for performance) and transparency:

shadow = true;shadow-exclude = ["WINDOW_CLASS=.*Firefox", "WINDOW_CLASS=.*Chrome"];# Exclude resource-heavy appsglx-no-stencil = true;# Improves performancealpha-threshold = 0.05;# Sets transparency threshold

Save the file after editing.

Switching to a Wayland SessionMost Linux distributions allow you to choose between X11 and Wayland at login. On the login screen, click the gear icon (or equivalent) next to your username and select a Wayland session (e.g., “GNOME on Wayland” or “KDE Plasma on Wayland”). This ensures Compton runs under the Wayland display server.

Starting Compton AutomaticallyTo start Compton when your system boots, create a Systemd service file:

sudo nano /etc/systemd/system/compton.service

Add the following content (replace your_username with your actual username):

[Unit]Description=Compton Window CompositorAfter=display-manager.service[Service]ExecStart=/usr/bin/compton --config ~/.config/compton.confRestart=alwaysUser=your_username[Install]WantedBy=multi-user.target

Save the file, then enable and start the service:

sudo systemctl daemon-reloadsudo systemctl enable comptonsudo systemctl start compton

You can verify Compton is running with:

systemctl status compton

Alternatively, add Compton to your desktop environment’s autostart (e.g., GNOME: ~/.config/autostart/compton.desktop).

Troubleshooting Compatibility IssuesSome Wayland applications (notably input method frameworks like Fcitx5) may not work seamlessly with Compton. To resolve this:

• Exclude Input Method Windows: Add their window class to shadow-exclude in compton.conf (e.g., WINDOW_CLASS=.*Fcitx).
• Use XWayland Fallback: If an app fails to render, launch it with GTK_USE_PORTAL=1 (e.g., GTK_USE_PORTAL=1 firefox) to force it into XWayland mode, which Compton handles better.
