Latest deployment BREAKS Debian TTY7

I have been using an Asus laptop with Debian bookworm paired with a USB-C DisplayLink KVM for ~1 year now

It has never 100% worked correctly 100% of the time. The external keyboard and mouse attached on the device always worked fine however. The display never did.

Last autumn, after a kernel upgrade I believe, OH THE JOY, the external monitor automagically started working. At that moment I was finally able to take full advantages of all my DisplayLink's features.

This was short lived.

Yesterday I thought I had found the perfect integration(Read: this project) for my setup so I deployed it. What it really did for me was make things worst by killing my TTY7, making it stay black and offering no cursor/content.

Looking around, it seems that this condition is also known on another DisplayLink project: https://github.com/DisplayLink/evdi/issues/480
