I'm stuck.
I have an iBook outputting 1024x768 and 1920x1200 on the external screen.
I had to adjust the external screen and it occurred to me to put it in pivot mode. This has worked before, but I haven't used it more than about twice.
Both screens went blue. There was no way to back out. I did a hard reboot: problem persisted. I disconnected the external display. iBook booted fine. I looked at display preferences, saw no way to adjust the other display without connecting it, and then connected it. Blue screen (of death) again.
After a little websurfing, I removed files from ~/Library/Preferences/ByHost that said display or windowserver. Reboot. Connect. Blue screen of death.
I removed the files again, rebooted, zapped PRAM (cmd+opt+P+R till I heard an extra chime) and booted up. Connected screen. This time, no blue screen of death, but the external display didn't show anything and the iBook screen had one (?) pixel in the middle glowing, otherwise black. edit: the iBook is not even giving the external display a signal, as evidenced by the screen's backlight not being on. I disconnected the external display, and internal display reset to 1024x768, so no "crash" this time.
Anyone have any suggestions? What more do I need to delete for total reset of display settings?
