[NOT CURRENTLY ACTIVE] macpro and two nvidias

Macpro fitted with a new gtx 1060, but the card doesn't have miniDVI output, so I can't use my cinema display, however there is a an old card that has that capability, so I'd like to use both cards if that is viable.

a. Is it generally possible to use two different nvidia drivers for two cards?
b. The 1060 would be used as cuda computing device, must support blender, what are my options?
c. New monitor? Something else?

System is running debian stretch and the new 1060 does show in lspci.

Check if the same driver will run both cards - I suspect it will.

For Blender you can choose which hardware is used for CUDA, in the system preferences - I'm assuming both cards plus the cpu will show up in the checklist.

Also see Two graphics cards in Linux - how?, which came up after a quick google.

Another option would be to buy an adaptor for the output cable.

@damo, sungreen, Thanks for reopening this, I'll have to re-research this at some point. p.s. Adaptor is a problem, it would have to be an active for this side of events (also I imagine expensive and possibly unreliable).

Does nvidia-detect say the 1060 is supported by the stock Nvidia drivers, which I assume you need for CUDA?

stevep; This?

Checking card:  NVIDIA Corporation GP106 [GeForce GTX 1060 3GB] (rev a1)
Your card is supported by the default drivers.
It is recommended to install the
    nvidia-driver
package.

irc I installed drivers/cuda from nvidia in similar cases.

I set the topic to [NOT CURRENTLY ACTIVE], since I don't have a card currently at hand.
