Did you try

 

"graphics mode"="1024x768x32"

 

at startup?

As far as I remember, it is exactly the same as I have written.

 

Plus, if you have a VESA 3 compliant graphics card, you can also enter a value for refresh rate like this:

 

"graphics mode"="1024x768x32@85"

 

Hope it works :)

You can also try removing the window preferences if you can get into -s mode:

 

Straight from Callisto installation instructions:

 

rm -f /Library/Preferences/com.apple.window*

 

rm -f ~/Library/Preferences/ByHost/com.apple.window*

 

rm -f ~/Library/Preferences/ByHost/com.apple.pref*

It also gives me the feeling that somehow it switched the outputs. Also try connecting your monitor to the second display out in your graphics card.

One more thing:

 

You could boot from Mac OS X DVD and edit the com.apple.Boot.plist from terminal. But I don't remember how to do it in terminal, since I use plist editors. Someone else could help you better at it.

1. -s

2.-uw /

3.rm -f /Library/Preferences/com.apple.window*

 

rm -f ~/Library/Preferences/ByHost/com.apple.window*

 

rm -f ~/Library/Preferences/ByHost/com.apple.pref*

(i copy it exactly right? with asterisks and everything?

If it won't work, I'll write you an applescript to switch monitor resolution.

You'll need to boot from DVD, copy it into your startup items in terminal. You also need to be dual booting to copy it into your hard drive. Or at least a network connection.

rm -f ~/Library/Preferences/ByHost/com.apple.window*

I don't think you can use the tilde (~) in single user mode. You haven't logged in, so it won't know how to resolve that as your user directory.

 

Besides, I sent a link to the following to him quite a while ago in a PM:

 

Boot into single user mode (boot option -s after hitting F8)

 

At the command prompt, type:

mount -uw /
rm -rf /Library/Preferences/com.apple.windowserver.plist
rm -rf /Users/(your-user-name)/Library/Preferences/ByHost/com.apple.windowserver*
rm -rf /Users/(your-user-name)/Library/Preferences/ByHost/com.apple.preference.displays*
reboot
