SOLVED Sax config shows up on non-existent screen
SLED 10 SP2 displays on wrong screen
The Sax2 configurator displays configuration dialogue on a screen that isn't plugged in or does not exist. This can also cause kdm or gdm to show up on the wrong screen leaving the user with the impression that X is not working right or that there is something wrong with the GUI.
Use "-p" switch to find out which cards you have and then use "-c" switch to select one for sax.
