At first upgrade to 12.04 the launcher would not pop out. After the first update it began to work, but it no longer does. I have altered the settings in APPEARANCE, and even pressing the super key does not work. I can get HUD by tapping, Shortcuts by holding, but not launcher by pressing. I have installed DOCKY as a work-around.

BTW 12.04 has been awesome!

Your upgrade has not been successful. As you now have a faulty installation, take this opportunity of backing up absolutely everything you might later want. Then have a go at some or all of the following:

sudo apt-get install ubuntu-desktop^

don't forget the caret in the above

sudo apt-get clean

sudo apt-get autoremove

sudo apt-get update

sudo apt-get upgrade

sudo apt-get -f install

Oh and unity --reset has been known to be good.

I've found that it is difficult to get it to pop out, but if you move the pointer hard and fast to the left it does then work, for me anyway.
