I am unable to see any Desktop in ubuntu. When I turn on computer, it just shows a black screen, no wallpaper.
However, if I open a program say chrome and try switching to Desktop with Alt + Tab, I still keep seeing an image of chrome window on screen. Here's a screenshot of the Desktop :
I am running Ubuntu 12.04
