Ubuntu "Could not get screen information" after upgrade

Question

I have upgraded from Ubuntu 14.04 to Ubuntu 16.04 and now when I open Display Settings I get the message "Could Not get Screen Information"(here is a screenshot):

There are multiple questions related to that and I think this answer was most useful. I logged in with another user and for him the Display settings menu works just fine. So following the answer I get to the conclusion: It's likely going to be something in .gconf or .config in which case you have to dig deeper. The problem is that I don't know how to dig deeper.

I have already tried solutions in many other answers. I have reinstalled nvidia drivers, ubuntu-desktop, xorg, xserver-xorg and all other tips from this answer(short of fresh install that I really want to avoid).

I am using ubuntu 16.04(4.4.0-31-generic amd64) on lenovo w530 laptop. Any ideas on how I can fix the issue?

If you do a ps x|grep control-center command in a terminal window, you may expect gnome-control-center as result. Close this control center window and instead type unity-control-center in a terminal window.

This control center will show your screen information. Pin it in the launcher for future use and possibly pin out the former one.

I am using the display menu in settings. Am I supposed to pin out "Settings" launcher? – Ivaylo Strandjev Aug 08 '16 at 15:13

The update to 16.10 completely removed the unity-control-center and only left the gnome-control-center - very weird. Installed the latter and removed the former, now the displays are shown - but the online-accounts button is missing. Classic Linux tinkery. – Nearoo Oct 15 '16 at 18:30
I had the same issue, in 16.04, suddenly, when attaching a new display. This answer solved my issue. – Christine Nov 28 '16 at 09:29

Perhaps obvious, but `sudo apt-get install unity-control-center` if needed. – khaverim Feb 27 '17 at 17:41

reinstalling the Unity Control center worked for me :

sudo apt remove unity-control-center

sudo apt install unity-control-center

(Ubuntu 16.04 with Unity)

There are dependencies that could result in problems. `The following packages will be REMOVED: ubuntu-desktop unity-control-center unity-control-center-signon` Give `apt-get install unity-control-center --reinstall` a try instead. – lobner Sep 11 '16 at 14:36

I've some trick for this: right click on screen, choose "Change desktop background", click on "All settings" and go to "Displays".

This way it's works for me, but through Settings -> Display doesn't

I had the same problem with 16.10. At some point, I did some clean up and one of the following removed unity-control-center:

sudo apt full-upgrade
sudo apt-get autoremove

The solution was to manually reinstall unity-control-center:

sudo apt install unity-control-center

I now see 2 Settings apps in Dash: "Settings" (gnome-control-center) and "System Settings" (unity-control-center).
