Как решить проблемы Единицы после обновления до Ubuntu 14.04?

После обновления до Ubuntu 14.04 я испытываю затруднения из-за своего дисплея. Я попробовал следующее для фиксации...

dconf reset -f /org/compiz/
setsid unity

... но при выполнении setsid единицы, я получаю следующие ошибки. Любезно советуйте.

rahul@rahul-Latitude-E6430:~$ setsid unity
rahul@rahul-Latitude-E6430:~$ unity-panel-service stop/waiting

Я также пытался переустановить...

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

... но никакая удача.

Кроме того, выполнение "единицы - значки сброса" бросает целый набор ошибок..
