Linux Compton配置出错怎么办 - 问答

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 *? 'Call'",
# "99:class_g  'Chromium'",
# "99:name *? 'Conky'",
# "50:class_g  'Dmenu'",
# "99:name *? 'Event'",
# "99:class_g  'Firefox'",
# "99:class_g  'GIMP'",
# "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。
