powerd
powerd
powerd is a system daemon that helps manage power states on the phone by providing a DBUS API (to be documented). This API is used by system services, not apps, to change the state of the system power and display. powerd also manages some things internally, like the activity timeout, although that code will be moving to Unity.
Bugs
Please report any bugs you find with powerd. If you have issues, you need to enable debug messages, which as of July 11 are disabled by default. In order to do that you need to edit /etc/init/powerd.conf and remove the comment (the # character) on the line that says "env POWERD_DEBUG=1". After doing that you can reboot the phone and reproduce your issue. Once the issue comes back, please attach the contents of /var/log/syslog to the bug. If you want you can filter that log to only have powerd entries using grep.
