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.

rahul@rahul-Latitude-E6430:~$ setsid unity

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..
