According to this output from /var/log/Xorg.0.log when I want to start X by writing
startx
Then the output shows.

The problem here is that it cannot find the layout section. So, instead, it using a default screen, which seems not to work because it has a usable configuration.

Question:
How can I create a configuration file, that my linux kernel or what ever going to read that file, when I’m writing startx to get the graphical screen loaded up?
- How should the file look like?
- Where should it be placed?
- What should the file contain?
Edit:
This occurs on Ubuntu 24.04 LTS armhf
