Along with NeteXt'73 you can modify the kernel, as well as the energy management system using eXt73. There is a lot of interesting scripts and updates.

I have long been familiar with this software from a Polish developer. About two years ago I installed it on my laptop. I mindlessly clicked on various scripts and realized that destroyed the system.
Now I see that the program has changed, not much but visible. Now I don't сlick on switches without thinking about the consequences.
Today for my laptop I updated the APM and put the policy of energy conservation of the battery.
The set comes on, Polish and English languages, everything is intuitive. If you need to update your video driver, you can easily do it.
If you need to work with repositories is easy.
Enable/disable system services without problems.
In General, I will show you some screenshots, you will understand about the possibilities of this miracle.
Installation latest version into Linux Mint:
sudo add-apt-repository ppa:netext/netext73 sudo apt update sudo apt install netext73
May the force be with you!!!
