How to install second radeon graphics card on Ubuntu 16.04?

I am pretty new to Linux and I have installed the first PowerColor Red Devil Radeon RX 580 w/ the AMD drivers, that is running fine.  Today my 2nd Red Devil Radeon RX 580 came in.  What is the easiest way to install the drivers for it? Thanks.

The easiest is probably the same way you did it with the 1st card?  Do the standard uninstall first, then add the 2nd card to the PC and a standard install.

I installed the drivers with the help of AMD's page http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Install.aspx

So If I uninstall it, and install it again how will Ubuntu know the drivers are for both cards? Thx

It's been a while since the last time I mined with Ubuntu, but I'm pretty sure that by default drivers are installed for all compatible hardware. So if there's 2 cards in your system then it'll install the drivers for both of them. Just try it, what do you have to lose anyway?

So I ended up doing exactly what you said, and it seems to be working just fine.  My hash rate has doubled.  Thanks for the simple instructions!
