Hi,

I have used X11VNC and it works fine ... No need to worry it will not crash your N900

1. Install X11VNC from Extra-devel repository on N900
2. Install a VNC Viewer on your PC
3. Start the X11VNC on N900
4. Start the VNC Viewer and PC and connect to the IP address of your N900

and VOILA! your ready to go ... You will see the N900 UI on your PC and
You can use your PC Mouse and Keyboard to control the N900
