a symptom

I am the Japanese and not good at writng English. I'm sorry to my language ability for you.
I sometimes get the following error when logging out of Xorg. It's a little different to [xf86-video-intel] flip_done timed out, but it's similar.
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:37:pipe A] flip_done timed out.

Using the video=SVIDEO-1:d kernel parameter doesn't work for me.
I'm running Arch Linux (4.17.2-1) on my laptop ThinkPad X220 with xf86-video-intel (my CPU is an i5-2540M).

Installing Arch Linux ARM on a SD card for Raspberry Pi 0 W and loading wifi credentials for headless usage

Advice

Before starting I highly suggest you create a new directory on your /home/user directory with an appropiate name for this task like rpi0alarm so you can change directory to /home/user/rpi0alarm and go through the following steps.

As I wrote this guide after collecting info from different sources (listed at the end) be mindful of your current path and the commands you are running to not damage your current installation on the host computer you are creating the SD Card.
