Here is my issue:
I (re)installed OS X (10.5.6) and was able to boot fine. I got a few updates (including OS) using Software Update. Now when I boot the display gets screwed up right after it gets past the first apple screen. It looks like the vertical tracking goes haywire or something. I never even see the desktop. The mouse is there and working, but I can't get anything else to appear. Any ideas?
As a note, I previously installed OS X the same way (type11), updated the software, and it ran fine for weeks, and then this exact same problem occurred. I assumed the install was corrupted, so I reinstalled. This time it started happening the first time I shut down and booted up, after getting updates.
I have read elsewhere in these forums that people experience similar problems when attaching an external display, but this is happening every time with the mini display. It seems like it must be a bad driver, but that doesn't explain why it seemed to start happening out of the blue. Thanks for any help.
