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. Thanks.
