a new version of powerd should be available fairly soon. i've
done the build for F17/x86 (but not the final 'fedpkg update' step --
i've asked peter for help with that), nor have i touched the ARM side.
martin -- _don't_ include this or higher releases in 11.3.1. no
guarantees.
the release number has jumped (previous it was -47) for a couple of
reasons:
- i wanted to leave a hole, in case 11.3.1 needs another
last-minute fix. i hope not.
- this is the first powerd with any support at all for the 3.x
kernels for XO-1 and XO-1.5. this support is fledgling at
best -- powerd will start, at least (better than nothing, eh?),
and will pretend to do many of the right things. there's
kernel support missing to make power management really work.
- finally, this powerd contains a fixes for #10856, and another
bug that i can't seem to find right now, both of which required
a fairly major change to how powerd manages the "inhibit-suspend"
flag.
until now, the inhibit-suspend flag would simply stop the
powerd state machine in its tracks when it came time to sleep.
if the dim and blank actions were scheduled _after_ the sleep
action (as they are in the default config), they would never
be reached. the buggy result is that when we ship XO-1 with
idle-suspend disabled, not only does the laptop not sleep, but
it also doesn't dim or blank. so much for saving power!
the change is that when powerd sees the inhibit-suspend flag,
it internally reschedules the sleep timer to be in the very
distant future -- long enough from now that it will never
happen. this lets the dim and blank timers proceed as usual.
SO: the possible downside is this: if you were expecting
inhibit-suspend to also keep the screen alive (a movie player
or slide-show activity might depend on this), it will no
longer do so. you'll now need to seperately inhibit screen dim
as well. i haven't updated the docs or the comments in the
powerd script. bear with me.
