Quick tip: Turning off laptop display under Debian 10

I’m running my rusty old ThinkPad T430s Laptop as (quite capable) homelab VM host under Linux/KVM running playground VMs. And because I’m accessing this machine only remotely over RDP I don’t have use for the internal laptop display.

After looking around what is the best way to turn the internal laptop display off I’ve settled for a simple solution using the linux command vbetool.
