Ubuntu系统下如何隐藏已挂载驱动器（无需安装GNOME及外部库）

The gsettings command you tried is tied directly to GNOME's Nautilus file manager, so the error makes sense—your system doesn't have that GNOME-specific schema installed, which you're intentionally avoiding. Let's walk through solutions tailored to common non-GNOME desktop environments and setups:

1. Xfce Desktop (e.g., Xubuntu) #

Xfce uses its native xfconf configuration tool, which comes pre-installed:

• Graphical approach:
  • Open Settings > Desktop > Icons
  • Uncheck the box labeled Mounted Volumes
• Command line approach:
  Run this to disable mounted volume icons on the desktop immediately:

  xfconf-query --channel xfce4-desktop --property /desktop-icons/show-mounted --set false
  

2. KDE Plasma Desktop (e.g., Kubuntu) #

KDE includes kwriteconfig5 for command-line tweaks, no extra libraries required:

• Graphical approach:
  • Right-click the desktop and select Configure Desktop and Wallpaper
  • Navigate to Desktop Icons > General
  • Uncheck Show removable devices
• Command line approach:

  # Disable the drive icon setting
  kwriteconfig5 --file plasmarc --section DesktopIcons --key ShowRemovableDevices false
  # Restart Plasma to apply changes
  kquitapp5 plasmashell && kstart5 plasmashell
  

3. MATE Desktop #

MATE uses dconf (pre-installed by default) for settings management:

• Graphical approach:
  • Open System Settings > Desktop > Desktop Icons
  • Uncheck Show mounted volumes
• Command line approach:

  dconf write /org/mate/desktop/desktop-icons/show-mounted-volumes false
  

4. Lightweight Window Managers (e.g., Openbox, i3wm) #

If you're using a minimal window manager without a full desktop environment, drive icons usually come from your panel (like lxpanel or tint2):

• For lxpanel:
  Right-click the panel, select Panel Settings > Plugins, find the Mount Devices plugin, and click Remove
• For tint2:
  Edit your tint2 config file (typically ~/.config/tint2/tint2rc), locate lines related to drive monitoring (e.g., execp = mount), and comment them out by adding a # at the start.

Quick check: What desktop environment am I using? #

If you're unsure, run this terminal command to confirm:

echo $XDG_CURRENT_DESKTOP
