If you just want to have long battery life and slow temperature, you can use acpi_call: a linux kernel module that enables calls to ACPI. With acpi_call_GUI you can easily install and configure it via graphic interface.
It is a java program that allows you to:
- install the acpi_call kernel module (kernel would be recompiled automatically after each update);
- Deactivate discrete GPU;
- Automatically deactivate discrete GPU on every boot.
If you have enabled systemd, or if you're using other linux distros that support it, you can use acpi_call_GUI_systemd.
See here: https://github.com/marcoDallas/acpi_call_GUI_systemd
Ensure that you have installed java and git, if not install these packages: git and openjdk-7-jre
After that open a terminal and type the following commands:
git clone https://github.com/marcoDallas/acpi_call_GUI.git
sudo chmod +x install.sh
How to use
To launch acpi_call_GUI search it in yuor dash and click on the icon, or type in a terminal:
sudo java -jar $HOME/acpi_call_GUI.jar
If you have a separate /home partition, you may need to use this command to launch acpi_call_GUI:
sudo java -jar /usr/local/bin/acpi_call_GUI/acpi_call_GUI.jar
