In Wikipedia is written that Gnome Shell in Gnome 3 uses Mutter window manager.

But ps x | grep mutter shows that Mutter is not running. Moreover I had experience with working Gnome Shell before I installed Mutter.

Does Gnome Shell really use Mutter? Which WM are used and which can be used with Gnome Shell?

Yes, mutter is used by gnome-shell but it's used as a library. The mutter binary is just a tiny program that links against libmutter. You could try like this:

lsof | grep mutter

Yes, I see, mutter is used, but as a library not as an executable – porton Nov 20 '12 at 20:13
