Uninstalling Compiz-Fusion ate up all title bars!
 

This is a weird situation! After title bars of all windows have vanished.

Could they be brought back?

Do you have metacy installed?

Do you mean Metacity? Compiz had an option for using Metacity but I never used it. I believe Metacity also went with uninstalling Compiz.

Metacity is what I meant, yes (:p). If if went during the removing of compiz, you need to reinstall it or another WM.

Actually, I wanted to get rid of Compiz as it seemed quite a resource hog. But, doesn't uninstalling Compiz activate Gnome's WM capacity back?

I think vanished-title-bar has something to do with the "window decoration" tasks of Emarald, which I was using in Compiz.

Then reinstall metacity,openbox, what ever you want. That should fix it.
