When certain models of Macintosh computers are booted headless (i.e. without a monitor) the Mac will not send a video signal. This interferes with the operation of certain remote-control software programs such as Netopia's Timbuktu. For example, the desktop icons may not work correctly, with unexpected bizarre behavior.|
Likewise, a monitor that has been plugged into a headless Mac will not work unless the system is either a) rebooted or b) put to sleep and awakened, both of which are impractical for servers that need to be up full-time or are remotely located.
For dual processor G4 models running OS X, such as the mirrored drive door model, there do not appear to be any commercially available adapters that solve the Timbuktu or monitor swap problem described above.
This solution is fast, quick and essentially no cost! It solves both the Timbuktu issue and allows hot-swapping of displays. Use the following at your own risk, of course; we are not Apple-authorized technicians and will not be responsible for any damage, mayhem, injury, death, global chaos etc. that results from the following:
Finally, we'll note that one can simply jump the pin holes on the computer's monitor port instead of using an adapter. But this makes it harder to simply pop a monitor on and off as you'll need to remove and replace the jumpers each time (and put them back in the correct holes without losing them).
