Display resolution for Dell Monitor gone after update

Question

After updating my Ubuntu 14.04 software today, my display properties stopped recognizing the Dell monitor I'm using.

I'm stuck at 1024x768 whereas this morning I had options to go to the rull resolution of my monitor.

Graphics card info was found using the following command...

lspci | grep VGA

With the following output:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

Any thoughts appreciated!
