Dual Monitors Ubuntu Jaunty

[Joseph Sinclair]

Most cards have a maximum resolution for all screens combined (for instance, an ATI 200M maxes out at 2048x1536) which is based on how fast it can push pixels across the (DVI/HDMI/RAMDAC) interface.
I would be surprised if you actually cannot exceed 1024x768 for a single screen, but getting multi-monitor support working well is a bit of a black-art still, and the combined max resolution of your card may be too small to handle the laptop screen and a large screen besides.

If you can let us know what card you're working with, it's fairly easy to google the specs to find it's (official) limits.

The thing you may have to do is use the appropriate configuration subsystem to add more resolution options to the system.  I've found xrandr in the latest Ubuntu and Fedora releases to be very poor at correctly configuring displays, even though the only purpose it has is to make that work better...
