If NetworkManager is disabled and you do not start it is the following present in dmesg and do graphics function correctly?
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

As you asked, I disabled NetworkManager and reinstalled 4.19.2 kernel, so rebooted and, after a few minutes, I got the journal log https://pastebin.com/QqCk95LG Graphics worked fine and no sign of error in journal

That is unexpected that a networking issue manages to cause a fault in the GPU.
If you are prepared to try a package from an unofficial repository https://wiki.archlinux.org/index.php/Unofficial_user_repositories#miffe contains the linux-mainline package currently at 4.20-rc2 to see if the issue has already been fixed upstream.
Or you could build the linux-mainline or linux-git package from AUR.
Alternatively you could bisect between 4.18 and 4.19 to find the cause.

I installed 4.20 kernel, but no joy! Same issue, so I went back to 4.18 :-(

I have experienced the same problem. My workaround is booting with the following kernel parameter:

intel_idle.max_cstate=4

I could reproduce it with just using wpa_supplicant and dhcpcd (followed the steps in the installation guide) and without using a GUI. The screen started flickering for a while, and then went pitch black.

I cannot reproduce the issue. Is it still valid for you?

The thread is 3 years old, and the kernel version was 4.19.1. This problem did not persist for later kernel versions, and is to my knowledge not present in the current version.
