E-gpu + Ubuntu - problem with "unsleep" of laptop

Question

Hi
This is my first post here, I was using this place as an spectator for long time and found many answers which helped me a lot.  
Now I have problem and didnt find any soluton over the internet.

Hardware:
Lenovo Thinkpad t480 with Thunderbolt 3
Intel integrated card
Egpu - Aours Nvidia GTX 1080

Software
Ubuntu 16.04
Nvidia drivers 384
cuda-repo-ubuntu1604_9.1.85-1_amd64
Windows 10 installed next to Ubuntu

I installed CUDA and blacklisted nvidia-drivers in /etc/modprobe.d  
and now after launch of ubuntu when there is no egpu connected by thunderbolt, OS run with intel driver and when I connect Egpu, it works and everything is perfect

I have an issue with &quot sleep&quot . When I go with sleep mode on ubuntu and then try to wake up. Laptop crash and I see message like that:

On Windows after sleep mode when I wake up Egpu work well. Problem is only on Ubuntu. Can anyone help me to to configure well my OS to work with Egpu also after wake up ?

Thanks for any help

Do not hotplugging. Since it is used as native GPU needs to be connected at login. If you want you can disconnect eGPU at login and system simply uses the iGPU.
