As you may know, Laptop Mode Tools is an application that enables the users to extend their battery life by enabling the Laptop Mode Linux Kernel and doing a bunch other tweaks.
The latest version available is Laptop Mode Tools 1.68.1, which has been recently released, bringing the below changes:
- Update details about runtime-pm in manpage
- Revert “Drop out reload”
- Log error more descriptively
- Write to common stderr. Do not hardcode a specific one
- Call lmt-udev in lmt-poll. Don’t call the laptop_mode binary directly.
- Helps in a lot of housekeeping
- Direct stderr/stdout to journal
- Fix stdout descriptor
- Install the new .timer and poll service
- Use _sbindir for RPM
Up to date packages will be soon added to the PPA, so installing the software on Ubuntu should not cause too many problems. Just add the PPA to your system, update the local repository index and install the laptop-mode-tools package:
$ sudo add-apt-repository ppa:ubuntuhandbook1/apps

Next, to access the configuration file, do:
$ sudo lmt-config-gui
Optional, to remove laptop-mode-tools, do:
