Good to know. Thanks for the useful remark.

Your comment sounds like you suspended the system once and resumed it
afterwards, while my description mentions "cyclic" :), meaning:
$ while true; do sh s2ram.sh; done
$ # connect-disconnect the hdmi display a couple of times
$ # NOTE: to avoid this manual step, I am thinking of a USB-controlled
HDMI switcher long-term

See above :)
BTW, using renesas-drivers-2020-06-02-v5.7 as base and performing the
use-case just described, I got today (with minimal effort):
