Which packages are missing. Please advise as before trying to use Unity Tweek Tool to change the desktop background I would

'right click desktop / change desktop background / settings / displays', and received "could not get screen information."

I know I've done something stupid. What's missing and how may I get it back, Please. Without possibly a major rebuild !

I performed the above and the response received was:

And for "What is the output of:"

lsb_release -a; uname -a

The answer is:

What is the output of the command
ls -l /usr/share/*/*/com.canonical.indicator.datetime*

Maybe reinstalling that package helps
sudo apt-get install --reinstall indicator-datetime

ls -l /usr/share/*/*/com.canonical.indicator.datetime*
is: -rw-r--r-- 1 root root 6634 Apr 7 2016 /usr/share/glib-2.0/schemas/com.canonical.indicator.datetime.gschema.xml
-rw-r--r-- 1 root root 465 Apr 7 2016 /usr/share/unity/indicators/com.canonical.indicator.datetime

Thank you guys. for all your help. After running 'sudo apt-get install --reinstall indicator-datetime' things seem to be back. Time and patience essential !!!
