From the login screen, poke the little button next to your name to reveal the session options.
opt for GNOME option in the menu and jump in with your password.
The Desktop
GNOME Shells desktop includes a minimal interface with just a top bar.
By default, theres no way to launch applications or view open windows without pulling up the Activities screen.
Of course, the standard Alt-Tab keyboard shortcut works.
The items on the top bar work similarly to the ones in Unity.
Extensions can also add their own options to this bar.
Unlike Unity, GNOME Shell doesnt use a global menu bar.
The menu bar stays in each applications window.
Of course, you could alsodisable the global menu bar in Unity.
Activities
nudge the Activities button on the top bar to pull up the activities overview.
The applications bar, known as the dash, only appears on the activities screen.
you could also browse and search for applications here.
From the Windows tab, you might view your open windows.
It only shows windows on the current workspace.
Drag and drop windows to move them between workspaces.
Unitys embrace of workspaces in the activities overview is a key difference from Unity.
For example, theApplications Menu extensionadds a GNOME 2-style applications men to the top bar.
