Introduction

This repository has a set of tools to manage the status of the NVIDIA graphics card on an Optimus™ setup. It now supports Solus with Budgie, MATE or Gnome desktop.

Three profiles are implemented in the nvidia-optimus-manager script:

  • intel: The Intel integrated GPU is used for display rendering and the dGPU is suspended by runtime power management. Running the nvidia-smi command gives
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
  • hybrid: The Intel iGPU is used for display rendering while the dGPU is still on and its driver is loaded for other tasks (e.g., deep learning, etc.). In this configuration, the nvidia-smi command produces the following output:
$ nvidia-smi

AUTOMATED SCRIPT INSTALL

  • Install the NVIDIA proprietary graphics driver

  • Download this repo, extract, cd into nvidia-optimus-manager-master, and from your terminal, run:

    sh nvidia-optimus-installer.sh
    

    Please note: Don't run with sudo

  • The script will automatically install and configure everything for Gnome, MATE, or Budgie.

  • Reboot

  • That's it!

Things to do before manual installation

  • Install the NVIDIA proprietary graphics driver
  • Blacklist the nouveau driver:

If you installed the NVIDIA proprietary driver from the Solus repo, this is automatically taken care of.

$ sudo mkdir -p /etc/modprobe.d
$ echo "blacklist nouveau" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
  • Install pciutils by sudo eopkg it pciutils

Reboot to let these changes take effect.

Installation

For Budgie:

  • 99-nvidia.conf: copy to /etc/lightdm/lightdm.conf.d/99-nvidia.conf # This may be the old path! User must confirm.
  • 99-nvidia.conf: copy to /etc/gdm/99-nvidia.conf # This is confirmed to be the path for new installs.

For MATE:

  • 99-nvidia.conf: copy to /etc/gdm/99-nvidia.conf

For Gnome:

  • 99-nvidia.conf: copy to /etc/gdm/99-nvidia.conf

For ALL:

  • nvidia-optimus-autoconfig.service: copy to /etc/systemd/system/nvidia-optimus-autoconfig.service
  • nvidia-optimus-manager: copy to /usr/bin/nvidia-optimus-manager

Then enable the service file at boot:

sudo systemctl daemon-reload
sudo systemctl enable nvidia-optimus-autoconfig

Dependencies

  • Linux-driver-management
  • NVIDIA proprietary graphics driver
  • pciutils: for the lspci command to find the pci bus id for the NVIDIA graphics card.

Usage

Three subcommands can be used with the nvidia-optimus-manager script:

  • Check the current configuration of the dGPU with the status subcommand:
$ nvidia-optimus-manager status
Current profile: intel
OpenGL vendor: Intel
Discrete graphics card power status: suspended
  • Switch profile with the configure subcommand (requires root previleges):
$ nvidia-optimus-manager configure intel
Info: selecting the intel profile

If the graphic card for the display rendering is changed during the switch of profile (e.g. intel -> nvidia, or nvidia -> hybrid), the user needs to log out before the switch can take effect:

$ nvidia-optimus-manager configure nvidia
Info: selecting the nvidia profile
Log out to take effect

Otherwise the switch happens immediately.

  • autoconfigure subcommand: Automatically configure the dGPU based on the presence of relevant configuration files (blacklist-nvidia.conf, 00-ldm.conf). This command is used in the systemd service file (nvidia-optimus-autoconfig.service) and the lightdm configuration file (99-nvidia.conf)
You can’t perform that action at this time.
