👁‍🗨 EnvyControl

EnvyControl is a program aimed to provide an easy way to switch GPU modes on Nvidia Optimus systems (i.e laptops with hybrid Intel + Nvidia or AMD + Nvidia graphics configurations) under Linux.

📖 License

EnvyControl is free and open-source software released under the MIT license.

⚠️ Disclaimer

This software is provided 'as-is' without any express or implied warranty.

Keep it mind any custom X.org configuration may get deleted or overwritten when switching modes, please review this README and the source code before proceeding.

🐧 Compatible distros

EnvyControl should work on any distribution of Linux, see tested distros.

If you're using Ubuntu or its derivatives please follow these instructions.

🖥️ Supported display managers

GDM
SDDM
LightDM

If your display manager isn't currently supported by EnvyControl you might have to manually configure it.

💡 Tips

Wayland session is missing on Gnome 43+

Latest changes in GDM now require NVreg_PreserveVideoMemoryAllocations kernel parameter to be set to 1 as well as nvidia-suspend services to be enabled for Wayland sessions to appear.

# 1. Re-run EnvyControl 2.2+ (either nvidia or hybrid mode)
sudo envycontrol -s nvidia

# 2. Now enable the required Nvidia services
sudo systemctl enable nvidia-{suspend,resume,hibernate}

# 3. Reboot

`/usr/share/sddm/scripts/Xsetup` is missing on my system

Please run sudo envycontrol --reset-sddm.
