I was just wondering if its possible to 'spoof' VNC screen sizes? ie I install a 'remote' PC with X11 on a minimal graphics card and then, while connecting in with VNC I pretend its as good as the graphics card/screen on the machine I'm using as 'monitor'. Tom

Good question Tom,
I have a suspicion that this is driver dependent. Meaning that VNC captures the screen signal on the downstream side of the graphics driver but before it ever hits the graphics card. I would guess (and that's all it is) that you could get any resolution you like if the driver can provide it.
Try installing the drivers for a high end graphics card. If the drivers themselves will install without the physical card being present, I really don't see any reason why it wouldn't work. I have successfully VNC'ed into a machine that had a physically corrupt video card and I VNC into boxes that have no monitor attached all the time.

AFAIK the driver on the server is irrelevant. It is the driver on the client that has to be considered. VNC is sending X-protocol across the net, not VDU signals. In the end, it is your 'monitor' machine that constrains what can be done.

when starting a vnc server on a linux machine you can specify the geometry of the screen, the colour depth and a few other options, so, yes, but don't forget that the larger the screen, the more network traffic it will use, and the slower the refresh (generally).
Thanks,
