Display in Settings menu shows
Could not get screen information
And Change Desktop Background on Right-Click menu just opens Settings.
Is it bug in update, or did I do something?
I had the same issue which I solved through re-installing the Ubuntu desktop by
sudo apt-get install --reinstall ubuntu-desktop
The above solution was not working (tried it under 16.04 LTS)
But thanks to
From a terminal window, I did
ps x|grep control-center
found gnome control-center process running, killed it using the good old kill -9
All display information are there
