Launcher, top Panel, and window decorations missing after 12.04 upgrade

First, try sudo apt-get -f install && sudo apt-get --reinstall install unity

Then, try unity --reset, followed by unity --replace; try doing this from the desktop and also from the console (switch via Ctrl-Alt-F1).


Try executing this command in the terminal:

unity --reset

It resets your Unity.


I got this resolved. Apparently the upgrade process wasn't through 100%.

I did the following commands:

sudo apt-get -f install
sudo apt-get update
sudo apt-get upgrade

And somehow after a restart it magically worked.
