 # EnvyControl
 
-# Introduction
+## Introduction
 
 EnvyControl is a program aimed to provide an easy way to switch GPU modes on Nvidia Optimus systems (i.e laptops with Intel + Nvidia or AMD + Nvidia configurations) under Linux.
 
-## Compatible distros
+### Compatible distros
 
 **This program was developed for Arch Linux** but it should work on any other Linux distribution.
 
 Debian and Ubuntu derivates might require rebuilding the initramfs after switching modes, you can rebuild the initramfs by running `sudo update-initramfs -u -k all`.

 I don't own any device with this particular hardware combination (in theory `integrated` and `hybrid` modes should work), please contact me if you do.

 The current state of Nvidia Optimus laptops on Linux is sad, each mode comes with a downside so you may find yourself switching modes quite often.

 This mode will power off the Nvidia GPU by blacklisting the Nvidia and nouveau drivers, as well as removing the card from the PCI bus using Udev rules.
 
 Since the dGPU is turned off your battery may last longer than on Windows, also you will be able to use Wayland and enjoy Linux without having to worry about overheating. **The downside is that you can't use any external screen because on most laptops the HDMI ports are wired to the dGPU.**

 This mode will render both internal and external screens using the Nvidia GPU, it requires the propietary Nvidia drivers to be installed and currently it's only compatible with Intel + Nvidia systems.

 This is the default behavior for both Nvidia and nouveau drivers, the dGPU can be accesed on-demand with `DRI_PRIME=1` for nouveau or `__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia` for the propietary driver.
 
-The propietary driver implements dynamic power management (like Windows) only on Turing and newer cards paired with Intel 8th+ gen processors.

 **The downsides are poor battery life on cards that don't support dynamic power management (like mine), external screens are laggy due to a broken reverse PRIME implementation on X.org and Wayland crashes if an external screen is connected (tested on Gnome).**
 
 Well, nouveau supports external screens on Wayland but it's laggy and prone to make your system crash.
