It seems, from reading blogs and forums, that many people like the idea of using Metacity’s compositor but are scared of changing the deep magic of gconf. In addition, there is nothing in the “–help” text to show that we have a compositor at all. Therefore, I propose a new switch to override the current gconf setting for the compositor, which will display in “–help”, and for symmetry another switch to turn it off again.
I am not sure whether –compositor and –no-compositor, or –composite and –no-composite, would be better names.
What do you think? Tell us at GNOME bug 545323.
