如何用Compton提升Linux桌面体验

Picom true 配置 opacity 202    来源:    2025-05-08

Compton(现分支为Picom)是一款轻量级X11合成窗口管理器,能显著提升Linux桌面视觉效果和性能。以下是详细配置指南:

一、安装与基本配置

  1. 安装最新版本
# Arch系
sudo pacman -S picom

# Debian/Ubuntu系
sudo apt install picom

# 手动编译最新版(推荐)
git clone https://github.com/yshui/picom
cd picom && meson setup --buildtype=release build
ninja -C build && sudo ninja -C build install
  1. 基础配置文件 (~/.config/picom/picom.conf):
# 启用VSync防撕裂
vsync = true;
use-damage = true;

# 阴影设置
shadow = true;
shadow-radius = 12;
shadow-opacity = 0.75;
shadow-offset-x = -15;
shadow-offset-y = -12;

# 透明度设置
inactive-opacity = 0.9;
active-opacity = 1.0;
frame-opacity = 0.7;
inactive-opacity-override = false;

二、高级优化技巧

  1. 性能优化组合(适用于Intel/NVIDIA显卡):
backend = "glx";
glx-no-stencil = true;
glx-no-rebind-pixmap = true;
xrender-sync-fence = true;
  1. 窗口规则定制(示例):
# 禁用终端透明
opacity-rule = [
    "90:class_g = 'Alacritty' && focused",
    "70:class_g = 'Alacritty' && !focused",
    "100:class_g = 'Firefox'"
];

# 无阴影窗口列表
shadow-exclude = [
    "class_g = 'Dmenu'",
    "name *= 'Notification'",
    "window_type = 'dropdown_menu'"
];

三、解决常见问题

  1. 屏幕撕裂处理
# NVIDIA用户专用设置
vsync = true;
backend = "glx";
glx-swap-method = "buffer-age";  # 或试 "exchange"
  1. 混合显卡笔记本优化
# 使用DRI_PRIME=1运行
DRI_PRIME=1 picom --config ~/.config/picom/picom.conf -b
  1. 内存泄漏预防
# 每2小时自动重启(cron定时任务)
[auto-restart]
enable = true;
interval = 7200;

四、视觉效果增强

  1. 模糊特效(需支持kawase blur):
blur: {
  method = "kawase";
  strength = 8;
  background = true;
  background-frame = true;
  background-fixed = true;
}
  1. 动态动画效果
# 窗口动画(需配合animations分支)
animations = true;
animation-window-mass = 0.5;
animation-stiffness = 200;

五、调试与监控

  1. 启动调试模式
picom --config ~/.config/picom/picom.conf -b --log-level=DEBUG
  1. 实时性能监控
watch -n 0.5 "cat /proc/$(pidof picom)/status | grep -i vm"

六、自动启动配置

  1. systemd用户服务 (~/.config/systemd/user/picom.service):
[Unit]
Description=Picom compositor

[Service]
ExecStart=/usr/bin/picom --experimental-backends -b
Restart=always

[Install]
WantedBy=default.target

启用服务:systemctl --user enable --now picom

提示:配置修改后需用pkill -USR1 picom重载配置。建议从官方示例配置开始,逐步添加自定义规则。
