This is support from Nvidia, with official Nvidia proprietary drivers

It's a software problem: Nvidia drivers conflict with nouveau in interesting
ways and, as Felix says, are very hard to remove once installed. This is
particularly a problem on high end laptops with more than one GPU - where
you need Optimus?? drivers.

I'd almost go further. A clean Debian install allowing the installation
to pick files should "just work". You might have lost some video
accelleration compared to the proprietary drivers but it should be fine.

If you need to install for something with dual GPUs, do a text only install
without installing any graphical environment _then_ and only then add
the appropriate magic to get dual GPUs to work.

You are using TDE. Do a text only install, uncheck all graphical desktops
 - you might need to install network manager if you are using wifi to 
install with. Reboot. Use nmtui or nmcli to connect to wireless.

At that point, install TDE - which is not currently a desktop supported
in the main Debian installer.

Resolve never to buy Nvidia again :)

All the very best, as ever
