Comment 6 for bug 446439

For me Simon's fix worked fine except for the icons, I had to use this line to restore my icons, and I'm not at all sure why this is different for me b/c we are all running Karmic here I would think but anyways...

sudo -u gdm gconftool-2 -t string -s /desktop/gnome/interface/icon_theme HumanLoginIcons

This worked like a charm and its all back to the regular login screen which I for one like quite a lot actually, thanks Simon and everyone else!
