Is PowerTop / TLP Still Useful To Save Power On Linux Laptops?
This system was running Ubuntu 17.10 and the configurations tested included:
- Ubuntu 17.10 in a "stock" or "out of the box" experience when using its Linux 4.13 kernel, GNOME Shell 3.26.1 with Wayland, and Mesa 17.2.2 atop an EXT4 file-system.
- Upgrading the Ubuntu 17.10 system to Linux 4.15 Git for showing the power consumption when using the very latest kernel cycle.
- This Ubuntu 17.10 + Linux 4.15 system then with Intel PowerTop installed and changing all the tunables to their "good" values for maximum power-savings.
- Installing TLP and using its default power-saving options.
