[olpc-help] USB2VGA adapter on the XO

I added the monitor and device sections, as instructed on http://wiki.laptop.org/go/Adding_USB_SVGA

However, the external monitor remains blank when I restart X

This appears to be further away from success than my earlier configuration which has an additional Screen section (Screen[SISUSBVGA]) and a ServerLayout section that states both screens and tries to configure X for an external clone.

With the latter I at least get a white screen on the external monitor, and the ability to have mplayer output to the external monitor (with DISPLAY=:0.1), in a small box in the center of the screen.  

Although this is not what we need! We need to have exact clone/mirror of the first display on the external monitor.

Please help!
