Ubuntu: How to fix Unity problems after upgrading to Ubuntu 14.04?



Question:

After upgrading to Ubuntu 14.04, I am having trouble with my display. I tried the following to fix...

  dconf reset -f /org/compiz/  setsid unity  

...but on doing the setsid unity, I get the following errors. Kindly advise.

I also tried to reinstall...

  sudo apt-get install --reinstall ubuntu-desktop  sudo apt-get install --reinstall unity  

...but no luck.

Also, running the "unity --reset-icons" throws a whole bunch of errors..
