Manjaro有多款电源管理软件可供选择,以下介绍几款流行的软件。


Note
通常情况下,应该只选择一款电源管理软件来管理功耗,避免因为安装过多的功耗管理工具导致冲突,甚至是适得其反


TLP

TLP是自动化电源管理的最常用方案


安装 TLP

TLP可以直接从Manjaro的存储库中获得,也可以使用其他包管理器或者终端命令方式安装

pamac install tlp

Now that it is installed, you need to start and enable the service. This can be accomplished with the command:

systemctl enable tlp --now


Note
TLP 1.2.2 and lower need another service as well: tlp-sleep.service


Configuring TLP

TLP can manually configured by editing the file /etc/default/tlp as described in The Official Documentation.


A simpler way to configure TLP is via the GUI tool TLPUI


To install TLPUI install the package tlpui using your favorite package manager or with the command

pamac install tlpui


Laptop Mode Tools

An Alternative to TLP for laptops is Laptop Mode Tools(LMT).


Installing LMT

To install laptop-mode-tools, enter the following command into your terminal:

pamac install laptop-mode-tools

Once installed, to enable LMT to start automatically every time you boot your computer, enter the following into your terminal:

sudo systemctl enable --now laptop-mode.service

LMT automatically configures some settings for you in order to optimize your laptop's battery life.


LMT Configuration

For configuration, the file to edit is /etc/laptop-mode/laptop-mode.conf}

The individual kernel modules can be configured from the configuration files present in /etc/laptop-mode/conf.d/


PowerTOP

PowerTop a diagnostic tool used to identify and report issues with power consumption and management. It can be used as a reporting tool, an automated power management tool or both.


Installing PowerTop

It can be installed as

pamac install powertop


Generating Reports

You can generate a report using powertop with the command:

sudo powertop --html

This will create the file powertop.html in the current directory. You can open this file in any web browser.

If you are using TLP for power management you may notice some differences in the recommendations between the tools. The article Comparing TLP with PowerTop reporting describes some of the reasons for these differences.


Automated Tuning with PowerTop

The command sudo powertop --auto-tune" will allow PowerTop to automatically tune power management based on it's recommendations.

From a practical perspective, the best way to use PowerTops auto-tuning is with a systemd service.

To create, start and enable a systemd service for PowerTop you can use the commands:

sudo sh -c "echo -e '[Unit]\nDescription=PowerTop\n\n[Service]\nType=oneshot\nRemainAfterExit=true\nExecStart=/usr/bin/powertop --auto-tune\n\n[Install]\nWantedBy=multi-user.target\n' > /etc/systemd/system/powertop.service"
sudo systemctl enable --now powertop.service


Temperature/Thermal Management

ThermalD

ThermalD, the Linux Thermal Daemon can be used to automatically handle CPU frequency scaling according to system load.

To install it, install thermald in your favorite package manager or use the command:

pamac install thermald

After installing it needs to be configured to automatically start at boot in order to work:

sudo systemctl enable --now thermald
