В стандартной установке оболочки gnome mouseфокус и sloppyфокус ведут себя одинаково. Причина проста: нет DESKTOP. Метод mouseфокусировки, в частности, нуждается DESKTOPдля правильной работы, но в стандартном воплощении такого нет в gnome-shell. К сожалению, это задокументировано только в документах. dconf-editorвсе еще имеет старое описание ключа / значений из времен метасити Gnome2 и gnome-tweak-toolдаже не предоставляет описание, не говоря уже о включении, DESKTOPкогда вы переключаетесь на mouseфокус.
Вот выдержка из mutter-3. ** / doc / how-to-get-focus-right.txt:
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".
Теперь вернемся к вашей проблеме. Вы должны «включить» DESKTOP, чтобы mouseфокус работал правильно. Это можно сделать:
- используя
gnome-tweak-tool> Desktop> Have file manager handle the desktop>ON
- используя
dconf-editor>> org.gnome.desktop.background>>> show-desktop-iconsпроверено
- в терминале работает:
gsettings set org.gnome.desktop.background show-desktop-icons true
Перезапустите gnome-shell после применения всех ваших настроек.
