11.04 uses Unity desktop. You can log out and log in with the classic gnome desktop to see your panel (if that was also upgraded not sure). –  Subhash Jun 21 '11 at 4:35

This question appears to be abandoned and unanswered, could you perhaps add more detail to your question? If this question no longer applies then you can either delete it or answer it yourself if you've solved the problem. Thanks! –  Jorge Castro Nov 29 '11 at 1:31

See if everything is installed:

sudo apt-get update && sudo apt-get install compiz compiz-gnome compizconfig-settings-manager

When you run that command it will tell you if it's already installed. –  wojox May 13 '11 at 4:03

The way I understand your question is that you call things like the three menus Applications, Places and System, for panels. These are really called applets. The "bar" you speak of, is called a panel. Then, if I interpret correctly, you do have a dark panel ("bar") at the top of the screen, but it does not contain the applets you're used to.

In the new Ubuntu interface, called Unity, there are no Applications, Places and System menus. The applets are also gone. Instead. You'll find the new launcher at the left of the screen and a button in the top left to display the dash -- a menu for files, applications, and everything else. You can also right-click the Files and Folders entry on the launcher to get a list of bookmarks (similar to places) and right-click Applications to display a category menu of the applications. The settings that were previously found in System, are now found in the power-button at the top-right of your screen.

In 11.04, you can switch back to the old user interface when you log in. Select your user name and then choose a session called Ubuntu Classic. In the new interface, it is not possible to use the old panel that you had on top. You can place it at the bottom if you like, though. But Gnome 2 is deprecated, so in 11.10 that won't be possible either. Everyone is moving to Gnome 3. If you give it a little time, I think you'll find that to be a very big improvement. Unity can do many things Gnome Panel never could.

If, after giving it a real chance, you come to the conclusion that you do want panels similar to the ones you've been using, but want to be more future proof, then I would recommend having a look at Xubuntu, which is based on Xfce. Their panels are very similar and can use Gnome Panel applets, but it is being actively developed and the panels really work much better.

Ha! Ha! Give it a little time... each time I upgrade there are problems. Dunno if I would have such problems with Gnome, but it has been 2 or 3 years and I still feel like that's debug code. Maybe because I upgraded on the same system from before compiz, but I'll soon switch to Gnome 3, for my own sanity. –  Alexis Wilke Feb 28 at 3:38
