Restart GDM on Ubuntu

Of late after the Kernel update on my Ubuntu, the GDM would not load up correctly.

I cannot click on Terminal, or shut down the system graphically.

I found a work around on this link It as simple as restarting the GDM

sudo /etc/init.d/gdm stop
sudo /etc/init.d/gdm start

If you wonder where to typed in this, Press CTRL+ALT+F1
