steamlink-alt-powermanager

An alternative powermanager implementation while I wait for a new build for the steamlink. It is in no way associated with valve, steamlink, or anything. Just a weekend project, use at your own risk ;)

Building

Make sure you have go 1.5+ available, clone the repo and run ./build.sh

The build script just sets GOARCH=arm and GOARM=7 and runs go build -o powermanager

Installing

You need ssh access to the steamlink (not covered here). Backup the old powermanager, copy the new on in it's place, and reboot.

./build.sh
scp powermanager root@steamlink:
ssh root@steamlink

cp bin/powermanager powermanager.bak
cp powermanager bin/powermanager
reboot -f

Notes

A simple quick-temporary fix; disables suspend timer

Registers system.powermanager alias with a single objectPath /powermanager and the following methods:

system.powermanager.Sleep in turn just runs poweroff -f currently system.powermanager.SetActivity(state uint32) does nothing

Debugging

To debug DBus messages, you can use dbus-monitor --system --monitor

I also have another repo so you can explore interfaces: github.com/mastercactapus/dbus-inspector

However, the stock powermanager does not properly implement Introspectable so you have to watch traffic

Known Issues

• It does not turn of the steam controller automatically.
