Ubuntu – No desktop icons after update to 14.04

14.04iconsupdates

Updated Ubuntu from 12.04 to 14.04 LTS. All seemed to go smoothly. After re-boot, the desktop displays the wallpaper and my user name appears with a password prompt. Ubuntu 14.04 LTS appears in the lower left. The mouse is detected and works as described below.
After entering my password, a message box appears with "System program problem detected. Do you want to report problem now? cancel report problem?

Selecting either choice results in the message box disappearing but no desktop icons appear and the wallpaper remains.
There does not appear to be any way to start a terminal, initiate a shutdown/re-boot and make any selection. I have to do a hard power button reset to get off the wallpaper screen.
I have already tried this recommended post:

Press Ctrl+Alt+F3-> ENTER YOUR username & password -> enter these commands-> sudo apt-get update -> sudo apt-get install –reinstall ubuntu-desktop -> sudo apt-get install unity -> sudo shutdown now -> Turn On your PC & check! – Jax-L May 2 at 16:11

and I have tried this similar posting:

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

Thanks for any reply.

I had similar issues when I first loaded Ubuntu 14.04. It ended up being my video drivers were not installed properly. The drivers I had issues with were connected to Nvidia and it seems that Ubuntu 14.04 did not come loaded to install these drivers. I also had to set the display to the default to get my drivers to work properly. The commands I used are as follows:

set display=:0

ubuntu-drivers devices | grep recommended

This command will give you an output stating the driver file that is recommended for your system. Then use the install command to install it: 

sudo apt-get install (recommended driver file)

sudo apt-get update

sudo apt-get upgrade

Reboot the pc, and see if this has repaired the problem.
