I have two questions :

First, I wanted to hide Ubuntu’s side-bar, so I set the settings in appearance to 'autohide'. The side bar did indeed disappear but when I roll over the left side, the side bar don't appear again. So, I am using a virtual box. Can it explain the fact that this bar doesn't show again when it is set to autohide.

Second, assuming I wouldn't be able to come over the problem, I pined to the dock every element of the sidebar, except the dash home. Is it possible either to pin it in the dock or to launch it from the terminal ?

I'm using virtualbox too and I suffer the same problem, this is a virtualbox bug. The easiest thing you could do is to install gnome-fallback and use it instead of unity, since you're not using the unity dash anymore.

Check this link with details on how to switch to the default gnome desktop, if it's not installed by default, you can open a terminal and use the command:

sudo apt-get install gnome-session-fallback

Then you can change your desktop in the login screen:

Auto-Hide of Side bar in Ubuntu desktop can be easily done as following:

  1. Go to System Settings
  2. Then go to Appearance
  3. Click on Behavior
  4. Turn on the Auto Hide Launcher (By default it is off)

Using GNOME Fallback is one way to work around this problem, but there are other workarounds that also merit consideration.

It is worth noting that if anyone wants to use a GNOME2 style desktop instead of the default Ubuntu desktop, then you should know that the MATE desktop is available. It IS (a fork of) Gnome 2, it is just not called Gnome 2 anymore to avoid conflict with Gnome 3.

That is worth knowing, because although MATE is certainly a bigger download than only installing Gnome-fallback, the difference is that IF you install MATE you will have a fully functional Gnome-2 style desktop that can do everything that you could do in Gnome-2, whereas Gnome-fallback desktop does not provide quite that much.

But if you don't care about having as much as you get with MATE, then Gnome-fallback works too.

Lastly, but not least, Gnome 3 really is a usable desktop too, IF you learn -all- the keyboard shortcuts. (Look them up some time, if you want to get good at Gnome 3.) And remember that Unity is getting better and better with each release also.
