因关闭VLC弹窗通知导致全局通知失效，如何重新启用所有通知？

Got it, let's fix that accidentally disabled system notifications issue. I've been there too—tinkering with app-specific settings and ending up toggling something system-wide by mistake. Here's how to get everything back working across common desktop environments and via command line:

• Hit the Super key (Windows key) and search for "Settings" to open the system settings panel.
• Scroll down to find the Notifications option in the left sidebar.
• Make sure the top-level toggle labeled Allow notifications is switched on (it'll be blue when active).
• Scroll through the list of apps below—you can leave VLC's notifications disabled if that's what you originally wanted, but ensure all other apps you care about have their notifications enabled.

• Open System Settings (search for it via the application launcher).
• Navigate to the Notifications module (under "Personalization" or "Workspace").
• In the left pane, select General Notifications and check that the Enable notifications checkbox is ticked.
• Switch to the Applications tab to fine-tune individual app settings: disable VLC here if needed, and re-enable notifications for all other apps you want to receive alerts from.

• Launch the Settings Manager and click on Notifications.
• First, confirm the Enable notifications option at the top is checked.
• Go to the Applications tab to adjust permissions per app: toggle VLC off, and turn notifications back on for every other app you need.

If you prefer terminal commands or can't access the graphical settings, try these:

• To re-enable notification banners system-wide:

  gsettings set org.gnome.desktop.notifications show-banners true
  

• Check if the notification daemon is running (it's required for notifications to work):

  systemctl --user status notification-daemon.service
  

• If it's inactive, start it with:

  systemctl --user start notification-daemon.service
  

If you used a tool like dconf-editor to tweak settings earlier, you can open it, navigate to org/gnome/desktop/notifications, and ensure both show-banners and enable (if present) are set to true.
