NUC11PHKi7C - plugging eGPU disable on-board 2060

[boyleo]

NUC11PHKi7C with RTX 2060 on-board.

I Put a RTX 2080 in Akitio Node Pro and connect it to rear Thunderbolt port.

The 2080 works fine, but it also disconnect the internal 2060.

The device manager shows yellow exclamation badge indicates that this 2060 has something misconfigured.

No video signal comes from HDMI or DP port on NUC.

I have to use a USB-C monitor plug into the front USB-C port or use HDMI connected to the 2080.

When I shutdown and disconnect Akitio. Upon restart the machine the 2060 stays disconnected.

I have to re-install the NVIDIA driver to get it back to work again.

Is this behaviour to be expected?

Can I not use the 2 GPUs simultaneously?

Why would plugging in external GPU disable my internal one, and it persisted even after unplugging?

Hi boyleo,

We were able to run some equivalent testing and found out that this issue is probably happening due to driver set conflicts between the RTX 2080 and the RTX 2060. 

Our suggestion would be to reinstall the latest RTX driver available while both GPUs are connected and "enabled". If this doesn't work, I would have to say that this behavior is driver-related and we may not be able to address this issue since it would be more on the side of the actual driver manufacturer: Nvidia*.

Hello boyleo

Thank you for your response. We are sorry to know that the behavior persists. In this case, our recommendation is to check this further with NVIDIA* Support or with the video card manufacturer for further assistance since this is a driver conflict with the NVIDIA* card.

Having said that, we will proceed to close this inquiry now. If you need any additional information, please submit a new question as this thread will no longer be monitored. Thank you for your understanding.

It has been a pleasure to assist you.
