  2. Install X11 server on your Windows machine (like VcXsrv or Xming)
  3. Connect to your Linux machine with SSH using the -X flag for X11 forwarding
  4. Test the setup with a simple X11 application like xeyes or xclock
BASH
# Edit SSH config to enable X11 forwarding
sudo nano /etc/ssh/sshd_config

# Add or uncomment these lines
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes

# Restart SSH service
sudo systemctl restart sshd

# Connect from Windows with X11 forwarding
# ssh -X username@linux-machine-ip
