debian live (9.2.0) user? + no3d ...

[Albretch Mueller <lbrtchx@gmail.com>]

 After burning onto a DVD:

 amd64/iso-hybrid/debian-live-9.2.0-amd64-kde.iso

 and running it from it, I am confronted with a user selection at start up.

 I have tried: "live" (and many other such combinations) to no avail.
All DL does is clearing the screen every 15 seconds and asking me
again.

 I see on the upper left: layout: PLASMA, on the upper middle:
interface: US flag, then the system time in big capital letters to the
middle left and next to it to the right a user selection area

 Also, I want for kde not to respond to "gestures" and such things, to
just work as if user were sitting on a plain old desktop (my case).
While using knoppix (also based on kde) you enter "no3d" on the
command prompt. How do you achieve the same result while using debian
live?
