[cron] Automatisch ausgeführte Shell für Linux-GPU-Fans von Curve Control

Umgebung

Linux Ubuntu bionic xfce

Einführung

Ich habe es geschafft, eine Lösung zu finden, indem ich im Internet nach der Kurve von Nvidias Gravo unter Linux gesucht habe (Steuerung des Lüfters entsprechend der Temperatur des Gravo).

Verfahren

1. Bereiten Sie eine Shell für die Lüftersteuerung vor (https://github.com/FedoraTipper/Nvidia-Fan-Curve-Linux).
2. Lassen Sie crontab beim Start automatisch laufen

1. Lüftergesteuerte Schale

/path/to/script

#!/bin/bash
#Make sure to enable nvidia-xconfig --cool-bits=4


#This new script works with version 378.13 driver
#Old script is not functional (on Arch, at least)
#Changed up some options and flags for nvidia-settings
#Added some comments for clarity, in case other people want to make improved forks

#enable headless mode 
#request lightdm installed - apt install --no-install-recommends xorg lightdm for debian/ubuntu
headless=true
verbose=false

if [ "$headless" = true ] ; then
    export DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0
fi

#Enable user defined fancontrol for all gpu
nvidia-settings -a "GPUFanControlState=1"

while true
do

    #gpu index
    i=0

    #Get GPU temperature of all cards
    for gputemp in $(nvidia-smi --query-gpu=temperature.gpu --format=csv,noheader);do
    
    if [ "$verbose" = true ] ; then
        echo "gpu ${i} temp ${gputemp}"; 
    fi

        #Note: you need to set the minimum fan speed to a non-zero value, or it won't work
        #This fan profile is being used in my GTX580 (Fermi). Change it as necessary

        #If temperature is between X to Y degrees, set fanspeed to Z value
        case "${gputemp}" in
                0[0-9])
                        newfanspeed="10"

                        ;;

                        ;;

                        newfanspeed="70"
                        ;;

                        newfanspeed="85"
                        ;;

                        newfanspeed="100"
                        ;;
        esac
        
        nvidia-settings -a "[fan-${i}]/GPUTargetFanSpeed=${newfanspeed}" 2>&1 >/dev/null
        
        if [ "$verbose" = true ] ; then
            echo "gpu ${i} new fanspeed ${newfanspeed}"; 
        fi
        
        sleep 1s
    #increment gpu index
    i=$(($i+1))
    done
done

2. crontab Einstellungen

Aufbau

Im Editor hinzufügen

Starten Sie den Editor

crontab -e

/tmp/crontab.xxxxx

@reboot /path/to/script

Mit einem Liner hinzugefügt

echo '@reboot /path/to/script' | crontab

Überprüfen Sie die Einstellungen

crontab -l

Ergebnis

@reboot /path/to/script
