  • - the distribution of the operating system Ubuntu 11.10;
  • - software "Terminal".
is worth noting that in the new assembly included 3 versions of shells, such an innovation has never been.True, they are not displayed by default, ie,they must be activated by setting the system bit by himself.Once set, you get to actually shell 3: Unity, Gnome and Gnome Shell.Each individual and each can perform any operation.
Before installing additional shells is recommended to update the software to the latest version, it uses "Update Manager", which can be found in the menu "System" (the "Administration").
Now run the program "Terminal" (analogue of the command line to Windows).In Unity, a large number of familiar elements disappeared, so quick start use the keyboard shortcut Ctrl + Alt + T. In the terminal window, type the following sudo apt-get install gnome-shell and press Enter.If you are too lazy to enter such a long string, copy it with Ctrl + C keys or Ctrl + Insert and plug in the terminal through the "Edit" menu ("Insert") or using the key combination Ctrl + Shift + V.
on the terminal screen will appear asking you to enter the root password (the analog of the Administrator in Windows).Enter it again and press Enter.During installation of the selected package in a terminal window will appear messages notifying about downloading additional packages.In the coming question is answered positively by entering the symbol Y or D (depending on the location of the system).
After installing the shell, type exit and press Enter (the output from the terminal).Now click on the gear icon in the top right corner of the desktop, from the list, select "End session."
When the login window on the screen to re-boot the system, click on the gear icon and select Gnome.Then enter the password if it has been set, and make input.You have successfully entered under environment Gnome.
