Incase it rings any bells, thought I'd just mention that screen
dimming has now stopped altogether for me. I've reset powerd pref
changes back to the default but no luck. It still powers off the
screen, but no back-light auto-dimming. The closest I have to narrow
things is that I noticed the dimming seemed to stop after I manually
adjusted the screen brightness with the keyboard (maybe I tried to
adjust it when it was already auto-dimmed, or some such permutation).
Many apologies for this, on further poking it turned out to be a
"problem between desk and chair" (user error). I misread the /etc/
powerd/powerd.conf comments and thought config_IDLE_DIM_LEVEL was
represented as a percentage brightness (0-100), but it is actually
based on the 0-15 hardware levels available. It was originally set at
5, and in an attempt to reduce the dimming up/down behaviour, I'd set
it to 50 (15 or above is no dimming), and then later assumed it was a
percentage.
Regarding dimming: I think it's less that the current dimming settings
that distracts me, but the apparent random wake-ups – I'm assume it is
network, or intermittent background activity that wakes things up.
I'll try reducing the config_CPU_IDLE_LIMIT and see if that helps
prevent seemingly random wake-ups.
Apologies,
