When I used twm, I could exit it from the menu (return to the tty where I run xinit), but how do you exit metacity? The man metacity does not mention this, but it refers to the panel menu (which I don't have). Maybe it's there?
I'm reading a number of sites on making ubuntu faster/more lightweight (e.g. this guide, and many mention replacing Metacity with Openbox. However, in 12.04 on an Inspiron e1405, I only see Metacity taking 11MiB and (fairly consistently) 0% CPU. Am I missing something? Seems like I would be optimizing zero to replace something that uses that few resources
