Second Monitor gone after initial setup from bootable pendrive

Hi @PatrickJenner, and welcome!

Hell happened. Your laptop is obviously haunted. We just don’t know by what to perform the correct exorcism, so we need more information. To that end, please see:

Please also provide the output of:

mhwd --list

And

mhwd --listinstalled

Hope you manage!


Tip:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Thereby improving legibility and making it much easier for those trying to be of assistance.

Please edit your post accordingly.
