It requires root for nvidia-settings but fails each time I make my own autostart on systemd
[Unit] Description=NVIDIA Fan Control on Wayland Arch After=graphical-session.target [Service] ExecStart=sudo /home/rob/Documents/fan.sh User=root [Install] WantedBy=default.target
I’m not good with command line stuff but is sudo necessary if you’re already running as root?
nope
Post your service file and the output of the systemctl status command for your service when it fails to start. Otherwise we will just be guessing.

- You shouldnt constantly check if that app is installed, especially not using package manager testing. Do it once.
- You forgot some argument to run the settings from CLI, it seems to try to launch a GUI
the reason for more than one elif is for different package managers like apt, yum and dnf, other than that it just skips it if the package is detected.
Afaik it uses cli to find the temperature. i couldnt set the temperature with nvidia-smi so i had to use nvidia-settings
gpuTemp=$(nvidia-settings -q gpucoretemp | grep ‘^ Attribute’ |
head -n 1 | perl -pe ‘s/^.?(\d+).\s$/\1/;’) echo -en “Current GPU temperature: $gpuTemp \r”Yes the loop is nice, but you know your packagemanager and that this package will not disappear randomly, so keep it out of this service script, its just an extra break point and wastes resources :D
The rest, idk
As soon as I get home I’ll do it. Afaik if you try to run it normally without root access it spits out errors about not being able to set the fan speed because it uses nvidia-settings as a dependancy. Also failed to mention this is a Wayland script, not xorg
