Thanks for testing, much appreciated. I'm unclear as to why the fix wouldn't be
working. Given that you have a built-from-souce setup, could you do two more
things to help out?

1. Please make sure that
$PREFIX/lib/plugins/powerdevil/action/powerdevil_dpmsaction.so was installed in
addition to the powerdevil binary itself. That's where the power management
service's screen turn-off logic (and the proposed fix) is located in practice.

2. Please provide some of that new debug output that I added in the same
commit, to get a rough understanding of how your screen turns blank. On a
system with systemd, the easiest way to make the extra logs show up in
journalctl is:

systemctl edit --user plasma-powerdevil.service

and in the free space between the top two comment paragraphs, add this line:

[Service]
Environment="QT_LOGGING_RULES=org.kde.powerdevil=true"

The new logging entries all start with "org.kde.powerdevil: DPMS:", they
describe what idle timeouts are set for the action to trigger and when the
screen actually gets turned off. Please paste some of those logs here. If
that's an issue because the screen is blank, I've found that switching between
virtual terminals (e.g. Ctrl+Alt+F7 and back to the original one, wherever it's
located as per `loginctl list-sessions`) will restore the screen to non-black.

Thanks!
