Details

Currently upower calls pm-powersave on startup/power state change. AFAIU this behavior is controlled by the recently-added [1] option "RunPowersaveCommand" in /etc/Upower/Upower.conf which defaults to true. The call executes "pm-powersave false" from pm-utils thus disabling powersavings on various subsystems according to scripts in /usr/lib/pm-utils/power.d. As discussed in [2] some of those are broken and this behavior is not always wanted and definitely undocumented (I just spent two days blaming kmod for not applying power settings in modprobe.conf).

A workaround is to block the above scripts by putting dummies in /etc/pm/power.d, but the real problem is upower _silently_ doing its magic. So, is it possible to either (a) change the default RunPowersaveCommand to false, and/or (b) add Upower.conf to "backup" array in PKGBUILD so that users' settings are not forgotten on update?

Thank you.

This has not been fixed in upower 0.9.17-1 which is in testing ATM.

upower in testing doesn't use pmutils anymore, but it's still a valid concern that a conf file in /etc isn't in the backup array.
