I do not know what happened.

I went to open my Display Control panel and nothing happens. All other panels open fine, but when I click on "Displays"... nothing changes and the windows for each monitor never appear. I tried repairing permissions, restarting, shutting down THEN restarting... nothing.

Here is what the console log says (I can't understand this stuff):

2005-04-14 12:30:04.501 System Preferences[803] Warning: TIFF image with unknown extra samples assumed to have unassociated alpha. RGB values have been premultiplied. Use tiffutil -cat to fix.

It also happens under a "New" user when I create one and go in to use it there too.

Grrrr...

Maybe try reinstalling the Displays prefpane? Sounds like it somehow got corrupted (possibly by a theme or something like that).

[LightWaver-67]

Nope... no themes or 3rd-party hacks...

How does one go about reinstalling such a thing...? I have the install discs... but never tried to do an individual install like that.

Thanks.

Can someone "stuff" and post or email their 10.3.8 version of: Displays.prefPane to me...?

Located in your HD > System > Library > Preference Panes

NOT the "Library" at the root, the one in your System folder.

That's the only other thing I can think of.

[LightWaver-67]

Scratch that!

I used Pacifist to extract it from the install CD - reinstalled the Displays Pref Pane.

STILL NO-GO!

Does anyone know what that gobbledy-gook code I pasted means...? What Tiff is giving it problems...?

UGH!!!

Have you tried removing files called com.apple.displays and maybe com.apple.systempreferences from ~/Library/Preferences?

Also, you may wish to consult this page about tiffutil as it seems to have some info on the issues console is complaining about with TIFFs. Do you by any chance have any TIFFs in ~/Pictures (or whatever folder your Desktop/Screensaver pane looks for Desktop pictures in)? Perhaps try removing them.

It seems to me, though, that the other items from your console log are more indicative of your problem; alas, I don't understand them.

Yep... I've tried trashing all-sorts of variants of pref's to no avail... even re-installed the pref-pane itself. We'll see... *sigh*

LightWaver-67, Maybe its because of your monitor and video card combination.

I have a dual monitor setup. I was replacing the primary monitor with a larger one. then the same problem you were having happened to me. (that is why I am here because I was searching for someone with the same problem). I knew the display preference was working before I tried hooking up the new monitor. I figure I would test out switching the monitor connetions with the 2 video cards to see if that would help. It worked and I get my display preference back. Funny, both cards in my G4 are ATI Rage 128 (with slight differences) yet different combination affected my Display Preference.

The only thing I can suggest is try another video card (or monitor if you have one) and see if your getting the same problem.

Good Luck. I hope this solves your problem.
