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?

Answer 1

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:

• How do I install and switch to the Unity 2D desktop?

Then restart with:

sudo shutdown -r now

Answer 2

Try to run terminal and type

sudo apt-get update
sudo apt-get upgrade

Sometimes these types of problem, run away with updates.

Answer 3
