I would like to know if it is possible to have a KDE theme (I think it's called Oxygen, but I'm not sure) for Ubuntu Unity? I really like the theme used in KDE but I prefer to use Ubuntu Unity. I wonder if anyone have tried that.
@chathurawidanage: i followed your instruction and installed oxygen-transparent successfully. However, I was not able to find the theme among the list in System Settings -> Appearance. There is no application appearance. I'm using Ubuntu 11.10. I also tried using Ubuntu Tweak but only the icon is available on the option. Any other way to activate this theme?
