Show the status of the virtual display and VNC service — whether running, display number, port, and connection info. Use when checking if VNC is available or troubleshooting display issues. Trigger on: "vnc status", "is vnc running", "display status", "check vnc".

Display the current status of the virtual display and VNC server.
Run these checks and present a status report:
# Service installation check
if ! systemctl --user cat virtual-display.service >/dev/null 2>&1; then
VD_STATUS="not-installed"
else
VD_STATUS=$(systemctl --user is-active virtual-display.service 2>/dev/null)
fi
if ! systemctl --user cat vnc-server.service >/dev/null 2>&1; then
VNC_STATUS="not-installed"
else
VNC_STATUS=$(systemctl --user is-active vnc-server.service 2>/dev/null)
fi
# Process check
XVFB_PID=$(pgrep -f "Xvfb :99" | head -1 || echo "none")
VNC_PID=$(pgrep -f "x11vnc.*:99" | head -1 || echo "none")
# Port check
VNC_PORT_OK=$(ss -tlnp | grep -q 5999 && echo "listening" || echo "not listening")
# Display check
DISPLAY_OK=$(DISPLAY=:99 xdpyinfo >/dev/null 2>&1 && echo "OK" || echo "FAIL")
# Service enabled check
VD_ENABLED=$(systemctl --user is-enabled virtual-display.service 2>/dev/null || echo "n/a")
VNC_ENABLED=$(systemctl --user is-enabled vnc-server.service 2>/dev/null || echo "n/a")
# Lingering check

# Server IP
SERVER_IP=$(hostname -I | awk '{print $1}')
VNC Service Status
Virtual Display: active/inactive/not-installed (PID: XXXX)
VNC Server: active/inactive/not-installed (PID: XXXX)
Display :99: OK / FAIL
Port 5999: listening / not listening
Connect: ssh -L 5999:localhost:5999 <user>@<ip>, then VNC to localhost:5999
Auto-start: enabled/disabled (virtual-display + vnc-server)
Lingering: yes/no (services persist without login session)
If anything is wrong, provide the specific fix command:
Persistent virtual display + VNC for headless servers. Four commands: /vnc-service:setup (install and configure), /vnc-service:run (ensure running + print connection info), /vnc-service:stop (stop services to free resources), /vnc-service:status (check health). Requires Debian/Ubuntu, systemd, sudo. VNC access restricted to local network via ufw firewall. Use whenever browser interaction is needed on a headless server — OAuth, CAPTCHA, 2FA. Other skills should call /vnc-service:setup as a prerequisite check and /vnc-service:run before browser operations.
Set up a persistent virtual display + VNC server on a headless Linux server. Installs Xvfb, x11vnc, creates systemd user services, sets a VNC password, and configures display :99. Requires Debian/Ubuntu (uses apt-get). Use this skill when a tool needs browser interaction on a headless server — OAuth login, CAPTCHA solving, 2FA prompts. Trigger on: "vnc setup", "set up vnc", "headless browser", "no display", "DISPLAY not set", "CAPTCHA requires browser", "OAuth needs browser", or when any other skill calls /vnc-service:setup as a prerequisite.
Ensure the persistent virtual display + VNC is running and print connection info. Call this skill whenever a browser interaction is needed on a headless server — before OAuth login, CAPTCHA solve, or 2FA prompt. If the service isn't set up yet, directs to /vnc-service:setup. Trigger on: "start vnc", "vnc run", "I need to solve a CAPTCHA", "browser login needed", "OAuth prompt", or when any other skill needs browser interaction on a headless server.
Stop the virtual display and VNC server services. Use when you no longer need browser interaction and want to free resources. The services can be restarted anytime with /vnc-service:run. Trigger on: "stop vnc", "vnc stop", "disable vnc", "turn off vnc", "shut down display".
