After entering

sudo sed -i 's/allowed_users=console/allowed_users=anybody/' /etc/X11/Xwrapper.config

I get

sed: can't read /etc/X11/Xwrapper.config: No such file or directory

I'm getting the same issue.

I had issues with this section initially as well.
Reflecting.
I would say the config files are in the wrong directory, or the config file was not made.

Below it’s traveling to the location.
Then you writing a New config, if it isn’t there.
Then setting permissions for access.

Later it’s recalled, and cannot autostart unless that file is fixed / present.
