Currently using 12.04. This time I was trying to use the application switcher, and it asked me to resolve a few conflicts most of which were not easy to comprehend.
So after some yes and no dialogue boxes leading me nowhere, I thought a reset should set things fine.
However, after preferences->reset to default, I can't see any window!! NONE whatsoever except the log out one when I press ctrl+alt+del
All I can see is the wallpaper and the mouse pointer. I cant even see the terminal or anything when I press alt+f2.
I am posting this when I switch to ubuntu 2d (I cant make out the difference between the two, but this just works for now almost the same way)
