Ubuntu – can’t see desktop except for background when log in Ubuntu14.04

14.04compizgnomeunity

I need some help, I installed Ubuntu 14.04 from 12.04. I had some problems when it rebooted so I had to install unity using sudo apt-get install ubuntu-desktop and continue tu update all packages using the virtual console. Ctr + Alt + F1.

But when I tried to login, after entering my user and password nothing loads, no dash, no launcher, etc. I tried everything but most I find is for older versions so I need help with this version or how to install a Gnome panel to replace unity and set it as defaul.

using ccsm show the unity plugin checked.

P.D.: I'm using an Acer Aspire 4520 with and Nvidia card.

Had a similar problem but I don't remember what I did exactly.
I'd suggest that if you installed anything that has to do with nvidia drivers, first remove them by running sudo apt-get remove --purge nvidia-*.
Then run the following commands and afterwards reboot your system:

sudo apt-get update 
sudo apt-get upgrade
sudo apt-get install --reinstall xserver-xorg-core
sudo apt-get install --reinstall xserver-xorg
sudo apt-get install --reinstall xorg
sudo apt-get install --reinstall ubuntu-desktop

This way, you can make sure that everything works with the default drivers and only afterwards try to install nvidia stuff.
