Unity doesn't load, no Launcher, no Dash appears

I have installed Ubuntu 12.04 on my PC, but when I boot Ubuntu, it simply shows the wallpaper, not any menus or other form of interface. My keyboard does nothing. What can I do to alleviate the situation?

Stupid question ; what happens if you push the mouse pointer up against the left hand side of the screen? – Adrian Jun 16 '12 at 21:36
It seems like your graphics aren't in order. Enter the system in recovery mode (when you boot select recovery mode. and there try Yumi's answer. – Alvar Jun 16 '12 at 23:27

Maybe you are having problems with graphics acceleration?

I suggest you try "ctrl+alt+F2", you should see a text terminal. Then install unity 2d using:

Then restart with:

sudo shutdown -r now

I'm sorry in advance if this question is dumb to you: you know that in linux, when you type a password in a terminal, it shows nothing right? (no asterisks like in windows: ****) You just type the password and hit enter. – Yumi Jun 16 '12 at 20:33

Try to run terminal and type

sudo apt-get update
sudo apt-get upgrade

Sometimes these types of problem, run away with updates.

Try choosing Ubuntu 2D from the login screen. From there you can investigate any driver issues with your graphics card, if any. I actually prefer Ubuntu 2D.
