As for the desktop environment.
1, ubuntu, using Gnome, this desktop environment is characterized by good stability, average aesthetics and super customization, but it can be configured beautifully. With compiz and other software, you can do whatever you want. This is another story. I am interested in going to Ubuntu Chinese Forum. /。 Post one of mine (I found the theme of Macbuntu online, and the imitated mac can be confused).
2、Ubuntu？ Netbooks also use Gnome, but with different desktop styles? Not quite the same as the desktop version. Pictures can be Baidu, suitable for small-screen netbooks.
3, Kubuntu, using kde, that is, K- desktop environment (K-Desktop? Environment), using Qt library, the dynamic effect is great, the UI is gorgeous (seconds kill Win7), and the operation is friendly (compared with Gnome). There are many practical Widget, similar to Windows gadgets, but the disadvantages are poor stability and less freedom of configuration than Gnome.
4. Kubantu? Netbooks, I don't know.
5, Xubuntu, using Xfce, the biggest feature of this desktop environment is to save resources, which means poor aesthetics, but the library and Gnome are Gtk libraries, so the icons are similar to Gnome. This desktop environment is very suitable for low-profile machines and saves resources.
Ps: If your hard disk space is large enough, you can install multiple desktop environments and change which one you want.
Specific commands (suppose you use Ubuntu? Dwarf)
Sudo? apt-get？ Installation? Kubuntu- Desktop
