Here is the output of "apt list | grep xorg": https://pastebin.com/jVRwiEHy, hope this lists everything you need.
I just tried to install debian instead of devuan and it worked flawlessly. Also, I get the exact error no matter if I use the netinstall or desktop .iso for installation of devuan...

Anyway, hope this info helps since I only have a hint of a clue of what I'm doing.

Edit: btw, I also suspected it to be a NVIDIA issue since on my second laptop without a graphics card, devuan works just fine out of the box.
