vncserver@:1.service

# Vncserver service file for Debian or Ubuntu with systemd
#
#  Install vncserver and tools
#  e.g. apt-get install tightvncserver autocutsel gksu
#
# 1. Copy this file to /etc/systemd/system/vncserver@:1.service
# 2. Edit User=
#    e.g "User=paul"
# 3. Edit the vncserver parameters appropriately in the ExecStart= line!
#    e.g. the -localhost option only allows connections from localhost (or via ssh tunnels)
# 4. Run `systemctl daemon-reload`
# 5. Run `systemctl enable vncserver@:<display>.service`
