While attempting to fix a problem with compiz settings manager, I got an idea from someone to purge compiz - sudo apt-get purge compiz. The compiz core packages are still intact however, the gui compizconfig-settings-manager is deleted and missing from synaptic. If I try to install through terminal I get:

The following packages have unmet dependencies:
compizconfig-settings-manager:i386 :

Depends: python-compizconfig:i386 but it is not going to be installed
Depends: python-gtk2:i386 but it is not going to be installed
E: Unable to correct problems, you have held broken packages

Any suggestions or insight is appreciated.

It seems, an essential package compiz is removed from your system. Unity depends on compiz package. You said that, compizconfig-settings-manager also get removed, it is normal, because "compizconfig-settings-manager" requires compiz, which is removed by the command.

I'd like to suggest to disable all the 3rd party PPAs, and enable all the official Ubuntu repository (including proposed). Then run sudo apt-get update and sudo apt-get install compiz commands. Also run sudo apt-get install compizconfig-settings-manager to get the useful software. *You should read this first though.

Click this link to get useful questions and answers about enabling various repository.

If your problem does not solved with the above procedure, I assume that, You have installed compiz from a 3rd party PPA, which is not supported officially. If this is indeed the case, then I'd suggest to enable that PPA first, then run sudo apt-get update and sudo apt-get install compiz.

Hope this helps!
