Ubuntu - Dependency Error

TRY THIS, when dependency error occurs during installation.

~$ sudo apt-get install -f

The command-line particularly help me when I was installing Google Chrome in my Ubuntu. During installation, this error occurred:

dpkg: dependency problems prevent configuration of google-chrome-stable: google-chrome-stable depends on libxss1;
however: Package libxss1 is not installed.
dpkg: error processing google-chrome-stable (--install): dependency problems - leaving unconfigured
Processing triggers for desktop-file-utils ...
Processing triggers for bamfdaemon ...
Rebuilding /usr/share/applications/bamf.index...
Processing triggers for gnome-menus ...
Processing triggers for man-db ...
Errors were encountered while processing: google-chrome-stable

So I issued sudo apt-get install -f  and reissued the command to install Google Chrome. Thereafter, everything is alright.

How to reset UBUNTU Unity and Compiz

I messed up with the Compiz configuration. I was supposed to disable Compiz and so I unchecked every option. But as a result, I lost desktop side bar launcher, the top desktop menu bar, and everything except for the mouse pointer. I restarted the computer using the power button but my desktop still came back just showing only the wallpaper and mouse pointer.

The Google advice that helped me were:

Ctrl-Alt-T //This is to open the terminal window.
$ dconf reset -f /org/compiz/
$ setsid unity

The above reset my Unity and Compiz. Instantly, my desktop returned to normal.

Additional, but I did not do this anymore because the former is enough then.
->  Install dconf tools, $ apt-get install dconf-tools.
