  • Bizarre Inverted Video Problem

    From Quiet Desperation@nospam@nospam.com to comp.sys.mac.system on Friday, July 25, 2003 16:12:56
    From Newsgroup: comp.sys.mac.system

    When I boot my dual G4 Mac (OS 10.2.6), everything is fine until it
    reaches the desktop, and I get inverted video. By that I mean it's like
    a photographic negative.

    It's not the monitor because I connected other computers and it's fine.

    It's not the video card because if I boot off a system install CD or
    hardware test CD it's fine.

    It's like there's something in software when I boot from the system in
    the internal drive.

    Anyone ever see anything like this? A web search has produced nothing.

    Open up System Preferences, and go to Universal Access. The "Seeing"
    tab has an option for Switch to White on Black, and chances are you
    somehow enabled it by mistake.

    (The key combination to activate that is Command-Option-Control-* ...
    so maybe you hit those keys somehow, and that did it.)

    Let us know if that helps.

    Same thing happened to me a few weeks back, and it was quite bedeviling.
    I realized that I must have triggered it by hitting the asterisk on the numeric keypad instead of the eject button when I was shutting the
    machine down (Command-Option-Control-Eject shuts down).

    Yeah, that was it, guys! Thanks a million!

    I never even knew that existed, but I could sort of tell it was doing
    it on purpose because it would boot to a blue desktop and then smoothly
    phase into the inverted version. I just installed Simcity 4 so I
    thought maybe that had narfed the video card settings or something.
    Looking at the key sequence, that was probably it because that's how I
    always shut down.

    Thanks again!
