+# Auto-Start Obsidian with Systemd
+
+Ensures Obsidian starts automatically on boot and stays running.
+
+## Installation
+
+### 1. Install Required Packages
+```bash
+sudo apt update
+sudo apt install -y xvfb xvfb-run
+```
+
+### 2. Copy Service Files
+```bash
+sudo cp /workspace/second-brain/obsidian.service /etc/systemd/system/
+sudo cp /workspace/second-brain/obsidian-mcp.service /etc/systemd/system/
+```
+
+### 3. Reload Systemd
+```bash
+sudo systemctl daemon-reload
+```
+
+### 4. Enable Services
+```bash
+# Enable Obsidian to start on boot
+sudo systemctl enable obsidian.service
+
+# Enable MCP server (optional, but recommended)
+sudo systemctl enable obsidian-mcp.service
+```
+
+### 5. Start Services
+```bash
+# Start both services
+sudo systemctl start obsidian.service
+sudo systemctl start obsidian-mcp.service
+
+# Check status
+sudo systemctl status obsidian.service
+sudo systemctl status obsidian-mcp.service
+```
+
+---
+
+## Managing Services
+
+### View Logs
+```bash
+# Real-time Obsidian logs
+sudo journalctl -fu obsidian.service
+
+# Real-time MCP server logs
+sudo journalctl -fu obsidian-mcp.service
+
+# Last 50 lines
+sudo journalctl -n 50 -u obsidian.service
+```
+
+### Stop/Restart
+```bash
+sudo systemctl stop obsidian.service
+sudo systemctl restart obsidian.service
+sudo systemctl restart obsidian-mcp.service
+```
+
+### Check Auto-Start
+```bash
+# List enabled services
+systemctl list-unit-files | grep obsidian
+
+# Should show "enabled" for both
+```
+
+---
+
+## Service Configuration
+
+### obsidian.service
+- **Type:** simple
+- **User:** intense
+- **Display:** Virtual Xvfb (:99)
+- **Restart:** Always (if crashes, restarts in 15s)
+- **Memory Limit:** 2GB
+- **CPU Quota:** 80%
+
+### obsidian-mcp.service
+- **Depends on:** obsidian.service
+- **Type:** simple
+- **Restart:** Always
+- **Memory Limit:** 512MB
+- **Health Check:** Verifies API is reachable on startup
+
+---
+
+## Troubleshooting
+
+### Obsidian won't start
+```bash
+sudo journalctl -u obsidian.service -n 50 --no-pager
+```
+
+### MCP server failing
+```bash
+# Make sure .env has valid API key
+cat /workspace/second-brain/.env | grep OBSIDIAN_API_KEY
+```
+
+### Can't connect to Obsidian
+```bash
+# Check if Obsidian is running
+ps aux | grep obsidian
+
+# Check virtual display
+ps aux | grep Xvfb
+
+# Manual test
+DISPLAY=:99 xdpyinfo
+```
+
+### Port already in use
+```bash
+# Check who's using port 27123
+sudo lsof -i :27123
+```
+
+---
+
+## Alternative: Supervisor
+
+If systemd doesn't work, use supervisord:
+
+```bash
+sudo apt install supervisor
+
+cat > /etc/supervisor/conf.d/obsidian.conf << 'EOF'
+[program:obsidian]
+command=/home/intense/.local/bin/obsidian --no-sandbox
+user=intense
+autostart=true
+autorestart=true
+redirect_stderr=true
+stdout_logfile=/var/log/obsidian.log
+environment=DISPLAY=:99
+EOF
+
+sudo supervisorctl reread
+sudo supervisorctl update
+sudo supervisorctl start obsidian
+```
