I was trying to get rid of dash plugins within the search, so I created & copied a list of my scopes and used:
gsettings set com.canonical.Unity.Lenses disabled-scopes "[$(find /usr/share/unity/scopes/ -name \*.scope -printf "'%P',"|sed -es':/:-:g' -e's/,$//')]"
from here which totally blanked out the search HUD -as in no access to installed apps or files. However when I try to use
gsettings set com.canonical.Unity.Lenses enable-scopes "['wherever.scope']"
to get indivdual (or all) back I get "no such key enable-scopes". So, what am I not doing right to get singular items (or the the whole thing if need be) back?
