Well, I have done a new ubuntu 11.04 installation and also added the gnome3-team ppa and installed gnome3, which is running now.
All is perfect, except one very annoying issue:
The windows I open, have no close button at all!
This is not the usual issue that new users have when they find that the maximize and minimize buttons are gone – in my case the close button is gone too, the window bar only has the title of the window in it, nothing else.
Nevertheless I have tried adding those buttons min/max buttons to the :close entry in gconf settings (using gconf-editor or gnome-tweak-tool). There were no changes, I still have no buttons whatsoever.
Something is obviously wrong, but can't figure out what.

Do you use the Gnome3 session or the Gnome classic? Do you use compiz or metacity as window panel? When I start to use gnome 3, I was the same problem. Try to install the Compiz fusion icon first. Select your windows manager, choose Metacity. Reload Windows manager. I wish it will solve your problem.
