💡 Fix: Session Startup or Signal 9 Error
If your desktop doesn’t load or you get “session exited too early” or “signal 9” errors, recreate the xstartup file:
cat > ~/.vnc/xstartup <<'EOF'
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export DISPLAY=:1
xrdb $HOME/.Xresources 2>/dev/null || true
xsetroot -solid grey
dbus-launch --exit-with-session startxfce4 &
EOF
chmod +x ~/.vnc/xstartup
vncserver -kill :1 || true
vncserver :1 -geometry 1280x720 -depth 24 -localhost no
🚀 Optional: Auto Startup Script
You can also create a quick launch script to start Ubuntu and VNC automatically:
nano ~/start-ubuntu-vnc.sh
# Paste script content (explained in video)
chmod +x ~/start-ubuntu-vnc.sh
bash ~/start-ubuntu-vnc.sh
