Ati Graphics - Mini And Ati Preferences Panel


Do I feel a fool, I have an ATI Preferences panel (not supplied with OS) which allows some control over the graphics.

I inadvertently (read stupidly) used the rotate 90 degrees option.

I now get to the login visibly but once logged in my display cannot handle and the screen remains blank.

How do I recover from this situation?

You have to find out where that preference panel saves its settings. I haven't found that out yet. Customer of mine did something similar once. It still worked fine with using a different display, though. We finally had to switch his display with a coworker's to "solve" the problem.
Addendum, fixed it. Got in by using shift key in safe mode, reduced the resolution and frame rate to the monitor, rebooted and then rotated back.

Useful to know.
