symptom

I am a Japanese and have low academic ability, so I am not good at writng English. I'm sorry to my terrible 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 which CPU is Intel Core i5-2540M Processor.

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

probably better performance
can run 64-bit software
comes without the proprietary video-driver blobs
