Hi everyone. Lately I've got my first eGPU with DELL XPS 13 9300 [build link]. All seemed fine until recently I discovered a very inconvenient behavior.

I've got two issues which might be connected in nature, but I'll describe them separately.

The boot issue

When your eGPU is connected to the laptop before startup and you launch it, everything seems fine:

  1. Connect the TB cable
  2. Power up laptop
  3. Close the lid

Result: BIOS startup sequence is shown on external monitor, boot process proceeds fine.

But then, after the boot sequence finishes, the DELL logo with the spinning circle is frozen in place on the monitor. Nothing happens after that, screen always stays frozen.

The only (very inconvenient) solution for now is to:

  1. Open the laptop - Windows login screen is being shown
  2. Log in into Windows
  3. Close back the lid

Now the external monitor starts to work again and shows the picture properly.

The lag issue

Now when you're finally able to work with your external monitor, the Windows is lagging. Menu lags, Explorer lags, everything lags.

Despite my initial thoughts that the eGPU didn't work and I'm using the iGPU now, I see that NVIDIA icon is active and there are a lot of processes used with the eGPU.

Windows Process Explorer also shows that iGPU isn't being used and is at 0% usage.

The only solution to fix this is to log off and log back in - then everything is smooth.

 

Any thoughts on how to fix this? Ideally I'd like to see this scenario:

  1. Connect the TB cable
  2. Power up laptop
  3. Close the lid, put the laptop on a stand (I only need the external monitor)
  4. See the boot process, log into the system and operate normally on the external monitor

Thanks for the tip! Either this or the update to the 2004 release build (which happened simultaneously so I don't know which one fixed the issue) it now runs perfectly fine.

Marking the thread as solved.
