Linux Mint（Cinnamon）下切换已保存键盘布局的快捷键设置方法

Got it, let's walk through how to set up a keyboard shortcut that cycles through your saved keyboard layouts—just like Windows + Space in Windows or GNOME. The steps vary a bit depending on your desktop environment, so I'll cover the most common ones below:

Since you mentioned GNOME's Windows + Space behavior, this is straightforward (and it's likely already set up by default, but let's confirm or adjust it):

• Open Settings (hit the Super key and search for "Settings" to launch it)
• Navigate to Keyboard > Keyboard Shortcuts
• Scroll down to the Typing section, then look for the action labeled Switch to next input source
• If the shortcut isn't already set to Super+Space, click the current shortcut field, then press the Super+Space combination to assign it
• Close the settings window, and you're done—pressing Super+Space will now cycle through all your added keyboard layouts

For KDE users, here's how to replicate the same behavior:

• Open System Settings (find it via your application launcher or right-click the desktop and select "Configure Desktop")
• Go to Input Devices > Keyboard > Shortcuts tab
• In the left-hand pane, select Input Method
• Locate the action Switch to Next Input Method
• Click the field labeled "None" (or the current shortcut), then press Super+Space to assign the combination
• Click "Apply" to save the changes, and test the shortcut to make sure it cycles through your layouts

Xfce requires a small helper tool to get the cycling behavior, but it's easy to set up:

1. First, install the xkb-switch tool (it handles layout cycling):
   • For Debian/Ubuntu-based distros: run sudo apt install xkb-switch
   • For Fedora/RHEL-based distros: run sudo dnf install xkb-switch
2. Open Settings Manager > Keyboard > Application Shortcuts tab
3. Click the Add button
4. In the "Command" field, enter xkb-switch -n (this command triggers switching to the next layout)
5. Click "OK", then press Super+Space when prompted to assign the shortcut
6. Click "OK" again to save, and now your shortcut will cycle through your saved layouts

If you're using a window manager instead of a full desktop environment, you can set this up directly via X11 config:

• First, confirm your keyboard layouts are configured by checking /etc/X11/xorg.conf.d/00-keyboard.conf (run cat /etc/X11/xorg.conf.d/00-keyboard.conf to view it)
• Add the following line to your startup script (like .xinitrc for X11, or your WM's config file e.g., ~/.config/i3/config for i3):

  setxkbmap -layout us,es,fr -option grp:win_space_toggle
  

  Replace us,es,fr with your actual layout codes (e.g., us,de for English and German)
• This line tells X11 to use the specified layouts and assign Super+Space as the cycle shortcut. You can adjust the shortcut by changing grp:win_space_toggle—other options include grp:alt_shift_toggle for Alt+Shift, or grp:ctrl_shift_toggle for Ctrl+Shift.
