I'm current using Ubuntu 11.10 and want to "try something old" on my machine (Window-like GUI). So if anyone know how to install ZorinOS GUI on Ubuntu 11.10 system (like we can do with KDE), please tell me about it. Many thanks!
The Windows-like GUI that ZorinOS uses is LXDE. You can install this from the repos (apt-get install lxde) then theme it, or you could install the lubuntu-desktop package and get the Lubuntu themed version of LXDE
