Laptop Mode Tools

Laptop Mode Tools, a Linux power-saving package, gets an update recently with many important bug-fixes. All users are recommended to upgrade to the new release.

Laptop Mode Tools controls the “laptop mode” feature of the Linux kernel. It saves power by spinning down hard drives, and in addition, it can be configured to tweak all sorts of other power-related things.

Version 1.67 was released 10 months after the last 1.66 release, which brings more reliably check for Device Mapper based devices, which is common these days with Crypt and LVM. See changes:

  • Relax minimum window size to accomodate low res screens
  • Fix variable name to comply with our “constants” assuptions
  • Get more aggressive in power saving for Intel HD Audio
  • Account Device Mapper devices
  • Add swsusp freeze support
  • Switch battery-level-polling default to True
  • Detect ethernet carrier, early and relibaly
  • changes the boolean setting *_ACTIVATE_SATA_POWER to a customizable *_SATA_POLICY, with backward-compatible defaults and documentation

      Don’t know why, but you may try installing python3-pyqt4 and python-qt4 via apt-get command or Ubuntu Software Center.

      This is very great tool, imrpoved my battery life on Ubuntu 16 from 2 hrs to 4.15 hours out of the box.

      I had to install that GKSU though, it wasn’t natively installed. You can do this with following.

      sudo apt-add-repository ppa:upubuntu-com/ppa
      sudo apt-get update
      sufo apt-get install gksu
