Super slow startup on Ubuntu 18.04  

Hi all,

I'm using a Razer Core X Chroma + EVGA RTX 2060 with a Lenovo T490 + Ubuntu 18.04.
In windows the eGPU worked flawlesly, plug and play.

I've installed nvidia-driver-440 with:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt install nvidia-driver-440

And after that I installed gswitcher from here: https://egpu.io/forums/thunderbolt-linux-setup/a-script-to-change-xorg-config/
BTW, I don't understand the difference between this script and this other: https://egpu.io/forums/thunderbolt-linux-setup/ubuntu-19-04-easy-to-use-setup-script-for-your-egpu/
Any understanding of what alternative to choose will be appreciated.

It is all almost working without any further tinkering, but I am suffering a tiny issue: Ubuntu takes too long during startup.
First it takes a lot during ubuntu logo. If I press ESC to check what's going on, I can read:

"A start job is running for udev Wait for Complete Device Initialization. (xxs / 3min)"

And after that, when I try to log in with my user, after I put my password and hit enter, it takes another minute or two until my desktop loads.
Unbutu loads afterwards, and it seems to be working good, I can see the applications on nvidia-smi, and the nvidia panel shows my screen information and the system details shows my nvidia GPU.

Thanks in advance for any help!
