Oh yes, and as more than one person has noted, VNC performance is incredibly poor on hardy. In fact, in my case, it's so poor that gnome-settings-daemon takes long enough to start up that the first thing to appear is a grey blank window that later (in a minute or so) paints to reveal an error that gnome-settings-daemon failed to start (or, more likely, just timed out, since it's running when the desktop appears and killing it to force it to restart gets it working again). It takes that long for the GNOME panels and the background image to appear and for the desktop to become responsive.
