There are other possible uses for multiples displays, like running different X servers on each, or using one of them occasionally for specific purposes for which it's better suited, like using a TV for video ;) > Unless there's a usage of x11vnc that I don't understand, there are > two issues with using x11vnc for this purpose. > > * First, WebOS does not have any available VNC client apps, so there's > no straightforward way of getting the TV to display the VNCed display. > > * Second, x11vnc allows remote viewing of an *existing* display.

As far as I can tell from the Wikipedia page x11vnc does have most of the features you are looking for: it can work with a virtual display (this appears to be similar to running two instances of X, so it might not support stretching your desktop to it) and it has a Java viewer applet that can be used to connect to it from a web browser. > But this does suggest a way to achieve the goal.

See above, as far as I can tell x11vnc can already do all of this. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
