The following description is from a (slightly edited) Mastodon post:

When I prepared a Raspberry Pi with the latest Raspberry Pi OS (based on Debian Bookworm) as a monitoring and observability display, I noticed the “wayvnc” package during the dist-upgrade.

Turns out this is a pre-installed VNC server package – at least on the Desktop variant.

But how can the VNC Server be configured and started and more importantly, how can I connect using a VNC viewer? Figured it out and wrote about it
