The new Pi 4 has two HDMI Ports. After booting Raspbian, the first screen (HDMI-0) should display the console and the second screen (HDMI-1) should display the X11 desktop.

My first thought was editing good old xorg.conf but newer debians don't have this file. Do I need to change config.txt?

Not sure how to start... Thx for your help.

    Good old xorg.conf is still used if you create it. X11 only use defaults if it doesn't find it.

    It should be doable with [screen] and [monitor] sections and so on. But I'm unsure how to select the hdmi output by the application (console ws. xserver). I watch your question as favorite.

  • While getting deeper into modern X11 configurations my requirements changed. So unfortunately I cannot answer my own question. Coming from an old xorg-conf-configures-x11 mindset I found the following links useful to understand the newer (xrandr focused) approach: How to use xrandr and Multihead.
