How to configure later-generation nVidia drivers to do their own power management now that it's supported on some models.
Applicable to Turing GPUs and Coffee Lake CPUs. Windbringer does not have the former (the GTX 1050Ti is a Pascal architecture, not a Turing architecture). Still, there are options.
A Linux program to handle GPU switching on Optimus laptops. Looks like a replacement for Bumblebee. Designed with Arch Linux in mind. Switches the external GPU on and off at need. Plugs into LightDM easily but can work with others with a little configuration.
In the AUR.
Works by auto-generating a Xorg configuration file and putting it into /etc/X11/xorg.conf.d/. If you already have custom Xorg configuration files at that location or at /etc/X11/xorg.conf , it is strongly advised that you remove anything GPU-related from them to make sure that they do not interfere with the GPU switching process.
If you have ever used the nvidia-xonfig utility or the Save to X Configuration File button in the Nvidia control panel, a Xorg config file may have been generated at /etc/X11/xorg.conf . It is highly recommended to delete it before trying to switch GPUs.
If Bumblebee is installed, you must disable its daemon and reboot.
The auto-generated Xorg config file will be automatically cleaned up if you uninstall.

WARNING: Switching mode automatically logs you out, so make sure you save your work and close all your applications before doing so.'
NOTE: Since version v1.2, power management is disabled until manual configuration is done. This choice was made because there is no catch-all configuration that works for all laptop models.
Default config file at /usr/share/optimus-manager.conf; create and edit /etc/optimus-manager/optimus-manager.conf
