Searched the forums with no real luck. Wondering if there's any method that will allow an iBook G3 900 (32MB) to run higher than 1024x768, which is the published res I could find at Apple.com. Looks like I'll be bringing my laptop in to work for some time to come, and I really need more screen real estate and the LCD is pretty dim under fluorescent lights. I'd prefer to sidestep the spanning hack if possible--I'm already driving the iBook really hard. Any thoughts, much appreciated.

The spanning hack does exactly what you want and I don't know of any other way to drive an external display at a higher resolution than 1024x768.

I guess to make spanning use as little resources as possible, you could make the external display the primary display, at whatever resolution you want, and set the iBook's screen as the secondary, and then change the iBook's display to a resolution of 640x480 at 256 colours and set a solid colour desktop on it and put no windows on it. Align it on top of the external display, turn the brightness down, and that's the best you can do, I think.
