[Linux-PowerEdge] Video cards for R610/R710

Hi Stephen,

we have graphic cards in several rack and towerservers. I never tried 
connecting two monitors, so I can only speculate on that point although 
and am optimistic that this works, if you use a card supported by a 
driver compatible with your OS.

But I know one impact on iDRAC: you will not be able to see anything 
with the Virtual Console Preview, once you disabled the onboard graphics.

I also found another trap: when you enter BIOS/UEFI setup and have a 
monitor connected via an extra graphics card, you might end up with a 
black screen. I never fully understood this, but on occasions we had to 
remove a card just to make the system autoswitch back to the onboard 
graphics. This might depend on the actual card and monitor, but it's 
good to learn how to change BIOS settings from the commandline.

Good luck,
