Possible dependencies

• xmrig
• ethminer
• BFGMiner

Setting up

Download the idleminer.sh script, open it in the editor, and set the executables variable to the desired command(s) / location(s). It might look something like this:

executables=(
    "xmrig -c /home/chiya/.config/xmrig/monero.json"
    "ethminer -G -P stratum1+tcp://[YOUR ETHEREUM WALLET]@eu1.ethpool.org:3333"
);

On the top of the script, there is also a few variables you can change:

# Time between each check
sleepValue=3;

# Idle seconds before starting xmrig
startAt=480;

# Number of times signs of user movement before stopping xmrig
# Setting this to 0 might cause the program to start and stop many times during idle
# Setting this too high might cause it to not stop at all
# Recommend between 3 and 10
userBackRetries=3;

# Path to executables (path(s) and/or command(s) works)
executables=(
    "xmrig -c /home/chiya/.config/xmrig/monero.json"
    "ethminer -G -P stratum1+tcp://[YOUR ETHEREUM WALLET]@eu1.ethpool.org:3333"
);


# It wasn't so easy to detect if any sound is being played
# Some programs will be detected as playing sound even tho it might not
#
# Please open all the programs you normally have open, make sure no sounds are being played, and run this command:
#   pactl list | grep -c 'State: RUNNING'
#
# This will be your standpoint of what "no sound" is.
# Normally, it will be 0, but some programs ( like kdenlive ) will increse this number to 1 even if no sound is played.
noSoundValue=0

Usage

Running the script as root is recommended to get the best hash value

Running it directly

sudo su
bash idleminer.sh

---

Setting up as a service

sudo su
nano /etc/systemd/system/idleminer.service

Paste in this content:

[Unit]
Description=Mining script
After=network.target

[Service]
Type=forking
ExecStart=/path/to/idleminer.sh
TimeoutStartSec=8

[Install]
WantedBy=multi-user.target

Save, and update the systemd with:

systemctl daemon-reload
systemctl enable idleminer.service
systemctl start idleminer.service

Setting up as a service (with screen)

Make a screen script, and save it somewhere. Content of that file might look something like this:

#!/bin/bash
screen -mdS MININGSCRIPT /path/to/idleminer.sh

Then create the service, but point to the screen script instead of the idleminer.sh script

sudo su
nano /etc/systemd/system/idleminer.service

Paste in this content:

[Unit]
Description=Mining script
After=network.target

[Service]
Type=forking
ExecStart=/path/to/screen/idleminer.sh
TimeoutStartSec=8

[Install]
WantedBy=multi-user.target

Save, and update the systemd with:

systemctl daemon-reload
systemctl enable idleminer.service
systemctl start idleminer.service

Now lastly, you can monitor the script by doing this:

sudo su
# Check running screens
screen -list
# Hopefully it's only 1 screen running, just do:
screen -r

Then you can detach by doing CTRL + A and then press d
