How do I set up a second monitor? Ubuntu 12.04 (Dell Inspiron 3520 Laptop
+ Dell E173FP monitor)

I have Ubuntu 12.04 installed as my primary os and I want to add a second
monitor. I went to system settings and displays, but my second monitor was
not recognized. I tried to click detect displays and it didn't recognize
it. I downloaded the drivers for the monitor, but I don't know how to
install them.
Files included in my driver download from dell.com for the monitor:
e173fp.cat
E173FP.icm
E173FP.inf
Readme.txt

Read me file:
