Cannot open "Display" settings, error "Could not get screen information"

Question

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

Thanks @Jens, reinstalling the Ubuntu Desktop has fixed the issue for me. :-) – Khuram Nov 26 '17 at 13:34

The above solution was not working (tried it under 16.04 LTS)
But thanks to
http://pifuge.com/ubuntu/fjvU-ubuntu-could-not-get-screen-information-after-upgrade
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
and launch unity-control-center instead

All display information are there

Could you tell, how you killed it? – Noidea Sep 20 '16 at 11:32

just a kill -9 followed by the process id returned by the previous command. I don't know your level of knownledge on Unix. I you want I can add some screen captures – Christ-OFF Sep 20 '16 at 19:25
yeah, thats what I tried, but it said no such process id... hmm, anyway I don't have a unity-control-center – Noidea Sep 20 '16 at 19:38
Why not giving it a try with
sudo apt update and sudo apt install unity-control-center ? – Christ-OFF Sep 27 '16 at 14:31
unity-control-center has only few settings. I do not see anything with Display setttings – Darius.V Apr 11 '23 at 06:10
