Displays can end up entirely disabled
Authored by: bq on Mar 26, '03 11:53:15AM
I've struggled with an issue that's related to this with my pBook 667. I often use a second monitor at one location, then sleep my machine by closing the lid, then open it back up at a different location without a second monitor.

What sometimes happens is that the machine is "alive" but there is no active display. Connecting a second monitor doesn't work, and hitting the detect displays/mirror displays button does nada.

I suspect that it has to do with screensaver mode. I have my screensaver set to require a password, and this may be blocking any attempts to detect further monitors.

Sorry for the worrying without solutions, but you might want to consider this if you find your machine is suddenly working in the blind.

Why don't you disconnect the external monitor, and then put your machine to sleep? This way when you wake it, it wont be trying to supply video to a monitor that isn't there.

I don't know whether if it's a bug or a "Strange/Hidden Function" but you can disable all your monitors. Here's how:

1- Plug any USB device
2- Plug the power cord
3- Plug a second screen
4- Close the lid. Wait for the mac to go to sleep.
5- Unplug the USB device
6- The mac will wake up, open the lid.

You're trapped... You can not do anything anymore... No sleep, no more screen... You need to restart using ctl-alt-power...

It happens to me almost every evening when I unplug all to go home. Someone almost always ask for a last minute little thing, I open the lid just after unplugged the mouse... Arg I'm stuck...

If anyone has an idea to prevent this stupid thing it would really help.
