I am trying to automate the 'detect displays' action of the displays menu (or system preferences pane).
It can be done in applescript via GUI scripting, but this is clumsy and slow.
Is there a UNIX command to detect displays?
Thanks

Nope, I don't think so. If you want one, file an ER with Apple.

You could use AppleScript in cli. man osascript

I am trying to write an applescript which changes my sleep settings, detects displays then starts a presentation in powerpoint, all automatically.
I want a slick way of starting a presentation, without the audience having to watch me do all those things manually. There is a slight security issue as well in that I don't really want my students to see what's on my computer, other than the presentation.
Changing sleep settings is no problem; nor is starting the PPT presentation - both work very quickly from applescript (with a bit of help from the cli). 'Detect displays' however requires GUI scripting, which first opens system preferences, monitors control panel then clicks the 'detect displays' button, then quits system preferences.
I was hoping that there might be a purely UNIX way of detecting the presence of a second monitor, which would remove the need for this part of the applescript.

Newer graphics cards automatically detect a new display. It's really spiffy--plug 'n play VGA.

I've actually noticed this on my 15" Powerbook for the DVI port. My Pismo never did it, but it's very handy that it auto-detects now. Gotta love it.

You could create a second user just for presentations such that your students wouldn't see anything but what was in that user's folder... which would basically be just the presentation.
