Wie man die Unity Remote-Search und -Amazon-Anbindung abschalten kann:

gsettings set com.canonical.Unity.Lenses remote-content-search none
if [ `cat /etc/lsb-release | grep DISTRIB_RELEASE | cut -d"=" -f2` \< '13.10' ]; then sudo apt-get remove -y unity-lens-shopping; else gsettings set com.canonical.Unity.Lenses disabled-scopes "['more_suggestions-amazon.scope', 'more_suggestions-u1ms.scope', 'more_suggestions-populartracks.scope', 'music-musicstore.scope', 'more_suggestions-ebay.scope', 'more_suggestions-ubuntushop.scope', 'more_suggestions-skimlinks.scope']"; fi
sudo sh -c 'echo "127.0.0.1 productsearch.ubuntu.com" >> /etc/hosts';
