On a slightly different vein, does anybody know if its possible to set up a mac to have 2+ "displays" on one monitor. I know that it is doable under Xwindows, where you slide the cursor to say the right side of the screen and it switches to a color "display", move it back to the left and your in a B&W "display". It seems like you should be able to set up 2 gDevices, 1 B&W and 1 Color, and then swap them to the monitor. Anybody out there know if this is even doable on a mac.

There is an FKEY called Switcheroo that does exactly this. Could you mail
me and tell me how to set up X windows to do it?

Could you mail >me and tell me how to set up X windows to do it? You're both a little off base. Some color screens, such as the Sun cgfour (I think it's the four), have two "planes", one in color and one in mono. The MIT X server for the color Suns will allow you to use each of these planes as a separate display. If you start out on the color plane and then move the pointer to the right off the screen, you end up on the monochrome plane. Some people use this to allow for less screen clutter, while others find that some applications are just too slow in color, but work fine in monochrome. Switcheroo, and programs that use the technique (e.g., SuperPaint 1.1), changes the depth of the screen, which is not the same thing as having multiple "screens" on a single physical monitor. As I said to Rob in a private letter, if such a mechanism were available on the Mac (which I think would be great), it should allow for any screen depth on each "virtual" screen. (I apologize if I got screens, displays, monitors, and planes terminology wrong. X and the Mac use different terms, and some terms get overloaded. Talk to me about synthesizer partials someday ;-) -- David Elliott dce@smsc.sony.com | ...!{uunet,mips}!sonyusa!dce (408)944-4073 "You see everything -- you're omnivorous."
