Leo reinstall did nothing. Is there anything else I could possibly do? I know it's not critical but it's very unsettling to me.
I should say that since the iBook isn't running any OS display drivers initially, that it would seem that either the back-light isn't energized at power-on or it's out-putting a display resolution that the internal display can't handle.
Your previous fix seems to indicate an NVRAM display setting is stuck.
It's possible that a display preference in your user's home directory or /Library/Preferences/ is corrupted and keeps setting the default display to a setting the iBook can't use on boot-up. Once the display drivers load, it over-rides the setting.
Look in /Users/YOUR_USERNAME/Library/Preferences/ByHost/
and move any file beginning with com.apple.windowserver..........plist to the trash.
Look in /Library/Preferences/
and move any file beginning with com.apple.windowserver..........plist to the trash.
Now reboot.
When you used the Command-Option-O-F on boot-up, did you see text on the screen?
Try these commands in Open Firmware: (note the added "set-defaults")
reset-nvram
set-defaults
reset-all
Once you get to the login window, choose "shutdown" (if available) and reboot.
Can't guarantee any of these will fix it. Just going down the path I would go. I don't think it's a huge problem. Just a query, have you ever used "Screen Spanning Doctor" to setup an external display
without mirroring?
