如何移除Ubuntu MATE通知面板中的图标？右键无移除选项

Hey there! I've dealt with this exact frustration before—right-clicking a tray icon in Ubuntu MATE and getting no option to remove it. Let's go through practical, step-by-step solutions to get those stubborn icons off your panel:

1. Use Ubuntu MATE's Native Notification Area Settings #

This is the first place to check, since MATE has built-in controls for tray icons:

• Open the Control Center (you can search for it in the Applications menu)
• Navigate to Panel > Notification Area
• You'll see a list of "Visible Icons" and "Hidden Icons" here.
• Simply select the icon you want to remove from the Visible list, click the left arrow button to move it to Hidden, then hit Apply.

2. Tweak the App's Own Preferences #

Some apps don't expose tray removal via right-click, but let you disable the tray icon in their internal settings:

• Open the app you want to remove from the tray
• Look for a Preferences or Settings menu (usually under the app's main menu or a hamburger icon)
• Search for options like "Show tray icon", "Enable system tray", or "Minimize to tray"—uncheck that box and save changes.
• The icon should disappear immediately, or after restarting the app.

3. Advanced Tweaks with dconf Editor #

For icons that still won't budge, dconf Editor lets you directly modify MATE's panel settings:

1. First, install dconf Editor if you don't have it:

   sudo apt update && sudo apt install dconf-editor
   

2. Open dconf Editor, and navigate to this path using the sidebar:
   org > mate > panel > applets > notification-area > screen0 > right
   (Note: If your tray is on the left, replace "right" with "left")
3. Look for the hidden-icons key. Click on it, then add the ID of the icon you want to hide to the list.
   • To find the icon's ID, check the icon-order key in the same directory—it lists all tray icons by their unique IDs.
4. After adding the ID, click Apply and restart the panel with this command:

   mate-panel --restart
   

4. Modify the App's Launch Command #

If all else fails, you can disable the tray icon by adding a parameter to the app's launch command:

• Open Main Menu (search for it in Applications)
• Find the app in the menu list, right-click it, and select Properties
• In the "Command" field, add a tray-disabling flag at the end. Common flags include:
  • --no-tray
  • --disable-tray
  • --no-systray
• Save the changes, then restart the app. The tray icon should no longer appear.
