power-rules-daemon

How to install

<your-package-manager-install-command> power-profiles-daemon
cargo install power-rules-daemon

Create the service ~/.config/systemd/user/power-rules-daemon.service

[Unit]
Description=Power Rules Daemon
After=graphical-session.target

[Service]
ExecStart=%h/.cargo/bin/power-rules-daemon
Restart=on-failure

[Install]
WantedBy=default.target

And enable both power-profiles-daemon and power-rules-daemon with:

systemctl --user daemon-reload
systemctl --user enable --now power-profiles-daemon.service
systemctl --user enable --now power-rules-daemon.service

Now you can add your rules to ~/.config/power-rules/config.toml

Rules example

Most users will use this daemon for gaming with rules like

[config]
default_profile = "balanced"  # Profile to use when no rules are triggered atm.
polling_interval = 5          # Amount of seconds before checking if a rule is triggered.
pause_on_manual_change = 180  # If the user manually changes the power profile (through the desktop environment gui, for example), the daemon is paused for n minutes.

# While a steam game is executed
[[rule]]
name = "steamapps/common"
profile = "performance"

# While launchers are executed
[[rule]]
name = "lutris"
profile = "performance"

[[rule]]
name = "heroic"
profile = "performance"

[[rule]]
name = "gamehub"
profile = "performance"

[[rule]]
name = "retroarch"
profile = "performance"

Rules are applied by order from above to below of the config file.

If no rules are currently triggered, default_profile will be the one used.

For package maintainers: How to distribute this program

Distributing this program in a linux distro is very easy! The installer should just:

• Install the program with: cargo install power-rules-daemon
• Copy the service (the user can enable it / start it himself).
• Add the program power-profiles-daemon.

TODOS

• Implement proper log files support.
• Tests (once features are confirmed).
• CI tests pipeline.
• Better docstrings, so nice docs can be CI pipelined.
• A man file is probably a good idea.
• Let's consider a few options for notifications, in case the user want to have them (it makes easier to visually confirm what's going on).
