如何将 Fluxbox 任务栏从 Compton（阴影）中排除？

我使用 Fluxbox 作为窗口管理器，并希望使用 Compton 作为合成器。但我无法将 Fluxbox 的任务栏从 Compton 的（阴影）效果中排除。

我如何让 Compton 忽略 Fluxbox 任务栏，尤其是它的阴影效果？现在，任务栏始终具有与非活动窗口相同的视觉外观。

这是我在 compton.conf 中获得的内容：

# Shadow
shadow = true; # Enabled client-side shadows on windows.
no-dock-shadow = true; # Avoid drawing shadows on dock/panel windows.
no-dnd-shadow = true; # Don't draw shadows on DND windows.
clear-shadow = true; # Zero the part of the shadow's mask behind the window (experimental).
shadow-radius = 10; # The blur radius for shadows. (default 12)
shadow-offset-x = 5; # The left offset for shadows. (default -15)
shadow-offset-y = 5; # The top offset for shadows. (default -15)
shadow-exclude = [
    "! name~=''",
    "name = 'Notification'",
    "name = 'Plank'",
    "name = 'Docky'",
    "name = 'Kupfer'",
    "name = 'xfce4-notifyd'",
    "name *= 'VLC'",
    "name *= 'compton'",
    "name *= 'Chromium'",
    "name *= 'Chrome'",
    "class_g = 'Conky'",
    "class_g = 'Kupfer'",
    "class_g = 'Synapse'",
    "class_g ?= 'Notify-osd'",
    "class_g ?= 'Do'",
    "class_g ?= 'Cairo-dock'",
    "class_g ?= 'Xfce4-notifyd'",
    "class_g ?= 'Xfce4-power-manager'",
    "_GTK_FRAME_EXTENTS@:c"
];

# Fading
#fading = true; # Fade windows during opacity changes.
#fade-delta = 5; # The time between steps in a fade in milliseconds. (default 10).
#fade-in-step = 0.03; # Opacity change between steps while fading in. (default 0.028).
#fade-out-step = 0.03; # Opacity change between steps while fading out. (default 0.03).
# no-fading-openclose = true; # Fade windows in/out when opening/closing

#detect-rounded-corners = true;
### highlighted top window rest dimmed
inactive-dim = 0.2;
inactive-dim-fixed = true;

# Window type settings
wintypes:
{
  tooltip = { fade = true; shadow = true; };
};

发射康普顿的命令是：

compton -C -G --config ~/.config/compton.conf

答案1

你可以使用“角色”规则。
看看我的是怎样的：

shadow-exclude = 
[
  "name = 'Notification'",
  "class_g = 'Conky'",
  "class_g ?= 'Notify-osd'",
  "class_g = 'Cairo-clock'",
  "role = 'fluxbox-toolbar'",
  "_GTK_FRAME_EXTENTS@:c"
];

总结

在您的 中~/.fluxbox/init设置：

session.screen0.toolbar.alpha:  255

细节

我遇到了同样的问题。Compton 的设置no-dock-shadow（即参数-C）似乎不影响 Fluxbox 的工具栏。man compton提示了几次，窗口属性_NET_WM_WINDOW_OPACITY可以设置透明度。

开始compton后，我做了以下操作来验证它是否正常工作。xprop并且compton-trans有一个交互式函数通过单击来指定一个窗口。

$ xprop
(select toolbar)
_NET_WM_WINDOW_OPACITY(CARDINAL) = 2139062143
WM_WINDOW_ROLE(STRING) = "fluxbox-toolbar"

$ compton-trans 100
(select toolbar)

$ xprop
(select toolbar)
_NET_WM_WINDOW_OPACITY(CARDINAL) = 4294967295
WM_WINDOW_ROLE(STRING) = "fluxbox-toolbar"

注意数值的变化。由于compton-trans可以设置工具栏透明度，因此更改 Fluxbox 配置中的不透明度（稍后 Compton 会采用该配置）似乎可行。
