KMenu (in KDE3.2)->System Settings->Display
Dual Head section
checked "Use Dual Head"
(this writes to xorg.conf file)
Then
KMenu (in KDE3.2)->Preferences->Control Center

Peripherals section, Display subsection (I think) and then I played with 
things.

The problem is that today I "upgraded" to KDE 3.3 and now I can't find that 
section, so I can't even do the things that worked at first, then stopped 
working yesterday. Sigh. KDE is getting so damn bloated and buggy, I think I 
will go back to DOS.

Well, I theorized that a signal to turn off was being sent to the monitor and 
linux was refusing to send a 'turn back on' signal, so I just wanted to see 
if the monitor was toasted or if it would still work, and we all know that 
things do work in Windows, as much as I hate to use it.

Thanks. Too scary for me, I think. I've gotten the impression over the years 
that tinkering with X if you don't know what you're doing can cause actual 
damage to hardware. So I think I'll pass.
