Fedora 27 Desktop（GNOME）屏幕共享配置问题求助

Hey there, I ran into the exact same issue on Fedora 27 GNOME a while back—turns out the screen sharing component isn’t installed by default. Let’s walk through fixing this step by step:

• First, install the required screen sharing package
  Fedora 27 uses vino as the GNOME screen sharing backend. Open your terminal and run these commands:

  # Check if vino is already installed
  dnf list installed | grep vino
  
  # If it's not listed, install it
  sudo dnf install vino vino-server
  

• Enable and start the vino service
  Once installed, you need to make sure the service runs automatically for your user:

  systemctl --user enable --now vino-server.service
  

• Restart the GNOME Settings app
  The Sharing panel won’t pick up the new package until you restart the control center. Kill the existing instance first:

  killall gnome-control-center
  

  Now open Settings > Sharing again—you should see the Screen Sharing option appear.

• Optional: Configure firewall and VNC settings
  To allow remote connections through your firewall:

  sudo firewall-cmd --add-service=vnc-server --permanent
  sudo firewall-cmd --reload
  

  If you want to disable connection prompts or encryption (useful for older VNC clients), use these gsettings commands:

  # Disable connection prompt (auto-accept)
  gsettings set org.gnome.Vino prompt-enabled false
  
  # Disable encryption (if your client doesn't support it)
  gsettings set org.gnome.Vino require-encryption false
  

That should get your screen sharing up and running. Let me know if you hit any snags along the way!
