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"

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

Actual cp. called police right after that
