Seems like there is a related lightdm issue: 
https://github.com/CanonicalLtd/lightdm/issues/17
I added a comment pointing to the #897572 bug report. In addition, I 
also installed GDM to see whether the same problem occurs. Indeed, not 
even the login screen is shown before I have pressed some keys.

To install testing I used the latest weekly build of the netinstaller 
with non-free firmware (firmware-testing-amd64-netinst.iso).

Best regards,
Dino
