Setup: XPS 9560 w/ i5-7300HQ, 1050 dGPU; eGPU: Sonnet 350 box w/ gigabyte 1660ti. I have started to recently have trouble with the nvidia drivers disappearing on me after I disconnect the sonnet from the xps thunderbolt port. At first, I thought this was due to improper disconnecting from laptop, but I also noticed that it refuses use the dGPU 1050 after disconnect too. I am going to try a clean install of the drivers using ddu and try manually disabling the 1050 before using the sonnet. If anyone has come across this or has any other ideas, thank you in advance.

My Setup: XPS 9560, i5-7300HQ, 16 GB ram Corsair Ram Vengeance, 1050 dGPU, Sonnet 350w Box w/ Gigabyte 1660 ti eGPU

Does the GTX 1050 dGPU encounter error 43? I have observed this issue when you pair same-brand eGPU. Windows automatically installs drivers that work for the eGPU and that somehow causes issues with the dGPU. The best approach is to use DDU and disable Windows auto-install then manually install the latest graphics drivers with both dGPU and eGPU enabled. Here's my build a while back with GTX 1050 dGPU + 1080 Ti eGPU that had similar issue.

Just checked and it is exactly what I get. I will run through ddu and see if that works.

Perfect, got it working and it seems stable now. Here are the steps I took for any one else who has trouble:
1) Download DDU and nvidia drivers for manual install (we won't be using Ge. Experience); 2) Change windows setting to stop automatically installing drivers; 3) Restart in safe mode and run DDU which will clean out all of nvidia related files (recommend clean and restart setting); 4) After restarting, install the nvidia drivers on the computer (custom install and do a clean installation, but do not have the eGPU connected yet); 5) Connect the eGPU, 6) After it recognizes the case, install the nvidia drivers again (express install this time, wanted to make sure the eGPU recognizes the drivers) and restart, 7) For me, it auto recognized it and switched to it. If not, try check the device manager under the display adapter and activate it from there.
