CONTEXT
=======

1. [HP DC7600 with onboard video](https://h20565.www2.hp.com/hpsc/doc/public/display?sp4ts.sn=2ua6120s9b&sp4ts.oid=472276&docId=emr_na-c00380853&sp4ts.pn=EH799UC&docLocale=en_US) Desktop PC with Windows XP /
Ubuntu
2. ASUS EN210 Silent Video Card

QUESTIONS
=========

How is configuration of onboard / installed video ports typically performed?

* for dual monitors (both onboard / installed video ports are active)?
* use Asus video card only (shutdown onboard)

Does the typical motherboard shutdown its video card automatically when it detects a video card?

I would like to understand the details of this particular configuration as well as the typical thought process (considerations and questions) that apply to the generic pattern.
