Ubuntu – How to open the Unity dash when hitting the top left corner of the screen

For Ubuntu 11.10

The solution depends on whether you are using the standard or 2D version of Ubuntu, which depends on your graphics card. (See: Am I using Unity or Unity 2D? )

Resizing the Dash in the standard Ubuntu

When opening the Ubuntu Dash, you should see three "window buttons" in the upper-left. Click the maximize button (the square) to switch between fullscreen and windowed mode.

Resizing the Dash in Ubuntu 2D

Install and launch Dconf Editor . Once it's open, navigate to the desktop > unity section in the left pane. You will see a form-factor option, which if set to 'Netbook' will made the Dash fullscreen, and if set to 'Desktop' will make the Dash windowed.

What about drag-resizing the Dash, like a Window?

There are many unconfigurable parts of Unity, and this is one of them. The Dash has two modes (fullscreen and windowed) and you can switch between them using the methods above. You can't drag-resize the Dash.

In defense of Unity's design, though, there's no reason you'd want to resize the Unity Dash to arbitrary dimensions on the fly. You don't "drag and drop icons [from the desktop to the Dash] in order to create shortcuts", as the question asker mentioned; that's what the launcher is for. The Dash is designed to be the sole focus on your desktop when you use it.

One (somewhat hackish) solution could be to simulate a Super keystroke every time you log in.

You can do this by adding the following xdotool command to your Startup Applications:
