有时，Window 键（用作超级键）会停止触发通常的桌面操作。
通常它运行良好，但每天有一两次它似乎会停止工作。
如果我打开 Gnome Tweaks->键盘和鼠标->其他布局选项并勾选和取消勾选任何复选框，则 Window 键会再次开始工作。该解决方法在Gnome shell：按超级键不起作用
但这个错误每天都会再次出现，这很烦人。有什么建议可以解释一下这是什么原因造成的吗？
Ubuntu 20.04，Gnome3 桌面。使用 dconf 重新映射了 ESC 和 CapsLock，但没有进行其他键盘映射调整。
我安装了终端仿真器 kitty昨天，每次我启动 kitty 时，Window 键似乎都会停止工作。所以这是一种可靠地触发故障的方法，但它甚至在我安装 kitty 之前就发生了。
当我启动 kitty 时，我在 journalctl 中看到这些消息：

无论我在 Windows 键有效时还是无效时运行该命令，此命令都是相同的。
$ gsettings get org.gnome.desktop.input-sources xkb-options
['caps:swapescape']
当 Windows 键不起作用时，我运行 xev 并按下该键，得到以下输出：
$ xev

从一份简单但全面的 Linux xkb 指南我对 xkb 系统有了更多的了解。当 Windows 键工作时，我看到：
$ setxkbmap -print -verbose 10
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/evdev...
Trying to load rules file /usr/share/X11/xkb/rules/evdev...
Success.
Applied rules from evdev:
rules: evdev
model: pc105
layout: se,us
variant: ,
options: caps:swapescape
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+se+us:2+inet(evdev)+capslock(swapescape)
geometry: pc(pc105)
xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc+se+us:2+inet(evdev)+capslock(swapescape)" };
xkb_geometry { include "pc(pc105)" };
};
当 Windows 键不起作用时，我看到 altwin（ctrl_win）、capslock（swapescape）和 deterministic（ctrl_alt_bksp）已启用。
$ setxkbmap -print -verbose 10
Setting verbose level to 10
locale is C
Trying to load rules file ./rules/evdev...
Trying to load rules file /usr/share/X11/xkb/rules/evdev...

variant: ,
options: terminate:ctrl_alt_bksp,altwin:ctrl_win,terminate:ctrl_alt_bksp,caps:swapescape
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+se+us:2+inet(evdev)+altwin(ctrl_win)+capslock(swapescape)+terminate(ctrl_alt_bksp)

xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwerty)" };
xkb_types { include "complete" };

xkb_geometry { include "pc(pc105)" };
};
过去我启用了 altwin(ctrl_win) 和 determinist(ctlr_alt_bksp)，但现在不再启用了。我如何找到这些设置仍然存在的位置？我相信我最初使用 Gnome Tweak 工具设置了它们。
