Displaying M.2 NVMe SSD Temperature on Ubuntu 24.04.2 LTS with LCD4Linux and hddtemp

In this article, we will guide you through the process of displaying the temperature of your M.2 NVMe SSD on an LCD display connected to a parallel port using LCD4Linux on Ubuntu 24.04.2 LTS. We will also use the hddtemp utility to retrieve the temperature of your SSD.

Prerequisites

Before we begin, make sure you have the following:

  • Ubuntu 24.04.2 LTS installed on your server
  • An LCD display connected to a parallel port
  • LCD4Linux installed and configured on your system
  • hddtemp installed on your system

Installing hddtemp

To install hddtemp, open a terminal and run the following command:

sudo apt update
sudo apt install hddtemp

Configuring hddtemp

After installing hddtemp, you need to configure it to work with your M.2 NVMe SSD. The configuration file for hddtemp is located at /etc/hdtemp.conf. Open this file in a text editor and add the following line:

/dev/nvme0n1

Replace /dev/nvme0n1 with the actual device file of your M.2 NVMe SSD. You can find the device file by running the following command:

lsblk

This will list all the block devices on your system, including your M.2 NVMe SSD. The device file will be listed under the NAME column.

Starting hddtemp

To start hddtemp, run the following command:

sudo hddtemp -n /dev/nvme0n1

Replace /dev/nvme0n1 with the actual device file of your M.2 NVMe SSD. This will start hddtemp and display the temperature of your SSD.

Configuring LCD4Linux

To display the temperature of your SSD on the LCD display, you need to configure LCD4Linux. Open the LCD4Linux configuration file in a text editor:

sudo nano /etc/lcdproc.conf

Add the following line to the end of the file:

plugin hddtemp

This will enable the hddtemp plugin for LCD4Linux.

Creating a hddtemp plugin

To create a hddtemp plugin for LCD4Linux, you need to create a new file in the /etc/lcdproc/plugins directory. Create a new file called hddtemp and add the following code:

#!/bin/bash

# Get the temperature of the SSD
temperature=$(hddtemp -n /dev/nvme0n1 | awk '{print $2}')

# Display the temperature on the LCD
echo "SSD Temperature: $temperature"

Replace /dev/nvme0n1 with the actual device file of your M.2 NVMe SSD.

Making the plugin executable

To make the plugin executable, run the following command:

sudo chmod +x /etc/lcdproc/plugins/hddtemp

Restarting LCD4Linux

To restart LCD4Linux and apply the changes, run the following command:

sudo service lcdproc restart

Testing the plugin

To test the plugin, run the following command:

sudo lcdproc -p hddtemp

This will start LCD4Linux and display the temperature of your SSD on the LCD display.
