I recently upgraded to 14.10 from 14.04 from the software center, 2 days later I changed my Desktop Background from Settings-Displays , I may have updated the system with minor 3 to 10 MB updates from software center after that, I guess. No major changes made.

Now when I try to change the Desktop Background again, it shows the Displays panel is broken.

It is transparent Except for the menu bar and shows "Could Not get Screen Information"

Moreover, even the settings menu frame seems to be broken, the resize icon in the bottom right is missing and I am unable to resize it.

Now how do I change my desktop background and how to fix this issue?
Also VLC Audio had issues after 14.10 upgrade , I resolved by reinstalling pulsa drivers, could this also have been due to the Upgrade?

NOTE : I am using the latest version of Binary tested Nvidia Drivers,
I had absolutely no issues whatsoever with 14.04

Aren’t releases such as 14.10 supposed to be Stable too even though they are not LTS or am I missing something here?
