Comment 2 for bug 459647

Confirmed here - and the option to enter the cursor theme in the compiz settings is now removed.

I can set the Obsidian cursor theme and it works perfectly under Metacity.

With compiz, the effects are rather fragmented - initially, the cursor doesn't appear. Switching to metacity gives perfect results, going back to compiz may show the obsidian cursor as the cursor passes over firefox window, and back to the default cursor when the cursor passes over the desktop.

I think this bug is perhaps more with compiz.
