Why did my desktop revert to a previous version?

Question

I have Ubuntu 11.10 installed. I shut down my computer last night, got up this morning (my kids had been trying to monkey around with it, thank god for the password protect) and when i opened my laptop up, it was already on and prompted me for my password.

After i did that, it logged on properly, but instead of my 11.10 desktop, i am seeing the 10.04 desktop. By this i mean, that the "Applications/Places" Top Bar Menu is there with the Bottom Bar that lists what windows you have open, but the crazy thing is, that when i go into "System Settings" from clicking on my name, the set up of everything else is 11.10........i dont get it.....help?

Answer 1

Seems that some part of Unity was UNchecked in the compizConfiguration Manager. In mine under desktop, I have checked: Expo, Ubuntu Unity Plugin, Desktop Wall, and Viewport swticher. All rest are unchecked.

Note what yours set for, try some changes to see if Unity comes back for you. If not set it back to where is was, and try another answer.

Answer 2

log out and while you are at the log-in screen click the gear icon near your username and choose Ubuntu or Ubuntu 2D.

probably this will help.
