13.04 - Unity isn't working after running `unity --replace`

How do I solve this problem? Somebody told me to do it (unity --replace) on this question Why is my desktop background black after upgrade to 13.04? and now it's stuffed.

When I run unity I get the following error:

compiz (core) - Info: Loading plugin: core
compiz (core) - Info: Starting plugin: core

unity-panel-service: no process found
Killed

My output from running sudo apt-get install --reinstall unity-services and sudo apt-get install ubuntu-desktop are:

Missing unity-services package?

It seems you're missing the unity-services package or it is not correctly installed. Just do this on a terminal:

sudo apt-get install --reinstall unity-services

To ensure that no more packages are missing, try this also:

sudo apt-get install ubuntu-desktop

Bad user profile configuration?

Create a new user and test its session. If everything works ok on that user, then the problem is with your user profile. To properly reset all unity-related settings, do this:

sudo apt-get install dconf-tools
dconf reset -f /org/compiz/

unity --reset-icons
