Comment 3 for bug 257192

"I am using Hardy and recently installed the ubuntu studio theme."

You did not install just the theme. You also installed -settings. This is most likely why you don't have the icons on the desktop for mounted drives as we turn that off for Studio.

Remove the -settings package. If that doesn't revert the changes look at the "Media" tab in Nautilus's preferences and System->Preferences->Removiable Drives and Media.

As this is not a bug, I'm marking as invalid. For further assistance on this issue please look toward #ubuntustudio on IRCs Freenode or the Ubuntu Studio Users mailing list. https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
