Ubuntu 11.10 will not include the classic GNOME desktop which is available alongside Unity in Ubuntu 11.04. Instead, Unity 2D will be installed to provide the Unity desktop even on systems without 3D graphics capabilities. Fortunately for fans of the old desktop, it will still be available to install from the repositories.
Install the classic GNOME desktop by installing the
sudo apt-get install gnome-panel
Before you log in, click the gear icon and select
GNOME Classic. This will
give you a traditional GNOME desktop with top and bottom panels and the Compiz
window manager. If you don’t want Compiz’s desktop effects, select the
Classic (No effects) option for the Metacity window manager instead.
If you have problems with the theme being messed up and
crashing, make sure you have installed any available updates. I had this problem
before upgrading my Ubuntu 11.10 Beta 1 installation.
There are a few differences between this desktop and the one in previous versions of Ubuntu. It’s now based on GNOME 3, so some applications like the file browser have changed a bit. Ubuntu’s indicators have not been ported to the new GNOME 3 panels, so panel items like the volume meter are GNOME applets. This is the interface which GNOME 3 uses as a fallback from GNOME Shell.
Thanks to Jeremy Bicha for posting about this on Planet Ubuntu and bringing it to my attention.
