switcheroo-control - 2.6-3+b1 main

For systems that have both an integrated GPU and a dedicated GPU, this
package by default will force the integrated GPU to be used to save power.
.
You can launch individual apps using the dedicated GPU by running them
with the environment variable DRI_PRIME=1. Or you can right-click on the
app (while it's not running) in GNOME Shell's Activities Overview
and choose the "Launch using Dedicated Graphics Card" option.
.
If this default behavior is not appropriate, uninstall this package or
set xdg.force_integrated=0 as a kernel command-line option in your
bootloader.
