Nvidia Akcelo

What is it?

A small service to help with some laptop setup on which the secondary screen plugged on HDMI is having a painful life (half-the-expected-framerate and/or very problematic frame-pacing). It's goal is automatically locking the GPU's clocks to their maximum speed when a secondary screen is detected on the HDMI port (and properly reseting the clocks when the screen is unplugged).

Installation (recommended method)

(⚠️ Not yet available ⚠️)

For Arch Linux-based systems (EndeavourOS, CachyOS, etc.)

1. Install the nvidia-akcelo package from the AUR.
2. Enable the service:

sudo systemctl enable --now nvidia-akcelo

Manual installation (not recommended)

1. Download the repository contents.
2. Copy the nvidia-akcelo file to /usr/bin/.
3. Copy the nvidia-akcelo.service file to /etc/systemd/system/.
4. Reload the service list:

sudo systemctl daemon-reload

5. Enable the service:

sudo systemctl enable --now nvidia-akcelo

Et voilà.

Dependencies

Nvidia Akcelo only works on Linux installations using Nvidia’s proprietary driver. If you use an open-source driver (Nouveau or Nova), this tool is likely unnecessary in the first place.

Also ensure the command-line tool ddcutil is installed (it should normally already be included in your distribution).
