专注于“鼠标”或“马虎”在 gnome-shell 上做同样的事情

Question

我的问题其实很烦人。我对鼠标焦点非常熟悉，但现在它不起作用。

在gnome-tweak-tool最后一个选项“windows”中有“windows focus mode”开关。我已将其设置为“鼠标”，但它不起作用。它的作用就像“草率”选项。我希望另一个 gnome 用户理解我的问题。

在标准的 gnome-shell 设置中，mousefocus 和sloppyfocus 的行为相同。原因很简单：没有DESKTOP。该mouse对焦方法，尤其是，需要DESKTOP以正常工作，但在GNOME壳没有这样的事情，在其标准的化身。不幸的是，这仅记录在 mutter 文档中。dconf-editor仍然有来自 Gnome2 metacity 时代的旧键/值描述，gnome-tweak-tool甚至不提供描述，更不用说DESKTOP在切换到mouse焦点时打开。
以下是 mutter-3.**/doc/how-to-get-focus-right.txt 的摘录：

Focus method  Behavior
    click     When a user clicks on a window, focus it
   sloppy     When an EnterNotify is received, focus the window
    mouse     Same as sloppy, but also defocus when mouse enters DESKTOP window

Note that these choices (along with the choice that clicking on a window raises it for the click focus method) introduces the following invariants for focus from mouse activity:

Focus method  Invariant
    click     The window on top is focused
   sloppy     If the mouse is in a window, then it is focused; if the mouse is not in a window, then the most recently used window is focused.
    mouse     If the mouse is in a non-DESKTOP window, then it is focused; otherwise, the designated "no_focus_window" is focused

However, there are a number of cases where the current focus window becomes invalid and another should be chosen.  Some examples are when a focused window is closed or minimized, or when the user changes workspaces.  In these cases, there needs to be a rule consistent with the above about the new window to choose.

Focus method  Behavior
    click     Focus the window on top
   sloppy     Focus the window containing the pointer if there is such a window, otherwise focus the most recently used window.
    mouse     Focus the non-DESKTOP window containing the pointer if there is one, otherwise focus the designated "no_focus_window".

现在，回到你的问题。您必须“启用”桌面才能使mouse焦点正常工作。这可以做到：

• 使用gnome-tweak-tool> Desktop> Have file manager handle the desktop>ON
• 使用dconf-editor>> org.gnome.desktop.background>> show-desktop-icons> 检查
• 在终端中，运行： gsettings set org.gnome.desktop.background show-desktop-icons true

应用所有设置后重新启动 gnome-shell。
