Linux Compton配置出错怎么办

当在Linux系统中配置Compton窗口合成器时遇到错误，可以按照以下步骤进行排查和解决：

确认Compton是否已安装及运行

首先，检查Compton是否已正确安装并运行：

ps -e | grep compton 

如果未运行，使用以下命令启动：

compton & 

检查配置文件路径及内容

配置文件路径因发行版而异，通常位于~/.config/compton.conf或/etc/xdg/compton.conf。使用文本编辑器（如nano）打开配置文件，检查以下常见配置项：

• backend：设置Compton的后端。常用的后端有xrender和glx。可以尝试更改后端以获得更好的性能或兼容性。
• vsync：控制垂直同步。可以设置为true（开启）或false（关闭）。
• shadow：控制窗口阴影。可以设置为true（开启）或false（关闭）。
• opacity和alpha：控制窗口透明度。这些选项允许你设置窗口的透明度级别。
• ignore_root：设置为true以忽略根窗口的透明度。这在某些桌面环境中可能会导致问题。

处理配置文件中的警告信息

在配置文件中可能会遇到一些警告信息，例如：

• Option no-dock-shadow is deprecated, and will be removed. Please use the wintype option shadow of dock instead.
• Option menu-opacity is deprecated, and will be removed. Please use the wintype option opacity of popup_menu and dropdown_menu instead.
• vsync option will take a boolean from now on. "none" is interpreted as "false" for compatibility, but this will stop working soon
• glx-swap-method has been deprecated since v6, your setting "undefined" should be removed.
• clear-shadow is removed as an option, and is always enabled now. Consider removing it from your config file
• paint-on-overlay is removed as an option, and is enabled whenever possible

这些警告信息表明某些配置选项已被弃用或移除，需要根据最新的Compton配置规范进行相应的调整。

重新启动Compton服务

保存并关闭配置文件后，重新启动Compton服务以应用更改：

killall compton compton & 

参考配置示例

以下是一个参考配置示例，可以根据需要进行调整：

# Shadow shadow true # no -dnd-shadow true # no -dock-shadow true # clear -shadow true detect -rounded-corners true shadow -radius 5 shadow -offset-x 1 shadow -offset-y 1 shadow -opacity 0.3 shadow -ignore-shaped false shadow -exclude [ "name 'Notification'", "class_g ? 'Dmenu'", "class_g ? 'Dunst'", "_NET_WM_STATE@:32a * '_NET_WM_STATE_HIDDEN'", "_GTK_FRAME_EXTENTS@:c", "_NET_WM_STATE@:32a * '_NET_WM_STATE_STICKY'", "class_g ? 'i3-frame'" ]; shadow -exclude-reg "x1000" # xinerama -shadow-crop true # Menu opacity menu -opacity 0.95 # Inactive opacity inactive -opacity 0.93 # Active opacity active -opacity 1 # Alpha step alpha -step 0.01 # Inactive dim inactive -dim 0.0 # Blur background blur -background false # Blur kernel blur -kern "3x3box" # Fading fading false fade -delta 1 fade -in -step 0.03 fade -out -step 0.03 fade -exclude [ ]; # Backend backend "xrender" mark -wmwin-focused true mark -ovredir-focused true detect -client-opacity true unredir -if -possible true refresh -rate 0 vsync false dbe false # paint-on-overlay true focus -exclude [ "class_g 'Cairo-clock'" ]; detect -transient true detect -client-leader true invert -color-include [ ]; glx -copy-from-front false # glx -swap-method "undefined" # opacity -rule # "99:name *?

'Im"  通过以上步骤，您应该能够解决Compton配置出错的问题。如果问题仍然存在，请检查系统日志以获取更多详细信息，并根据具体情况调整配置。
