Note that this is not an exhaustive list of dependencies because some other dependencies are probably already installed on my system. After a few attempts of the whole process, I figured that the following were the prerequisites for configuring and installing Qt5 on my system. The Qt5 wiki is an awesome resource and provides detailed instructions for building from source code. Therefore, I decided to install it from source. I have environment-modules already set up on my system and it would be simple to add another module for Qt. There is also a Github repository which provide DKMS (dynamic kernel module support) for some of these drivers. For example, the motherboard that I am using has Nuvoton NCT6687D-R chipset, which apparently does not have any i2c driver yet. One has to be careful to load the correct chipset driver. However, detailed instructions are provided in the OpenRGB Readme and requires patching the kernel to include modules that provide i2c driver for several chipsets.

I do not have any RGB via SMBus, so I did not need any configuration. To make it accessible to the normal user, I copied the les file provided in the OpenRGB source code to /etc/udev/rules.d and reloaded the udev rules. The root user could now access the Wraith Prism using sudo openrgb.

There are two important steps after the installation: providing USB access and SMBus access (for controlling RGB RAM and certain motherboard on-board LEDs). Sudo ln -s /home/saikat/Downloads/apps/openrgb/openrgb-build/openrgb /usr/local/bin/openrgb # clone from git this should create a directory called 'OpenRGB' Installing Qt5 from the Ubuntu package manager is easy: Installing OpenRGB also requires Qt5 - a framework for cross-platform software development. Configuring OpenRGB from source requires the following dependencies: sudo apt install build-essential libusb-1.0-0-dev libhidapi-dev pkgconf I used the USB connector for the RGB fan, because the RGB header on MSI MAG B550M Mortar motherboard is not yet supported by OpenRGB. I used OpenRGB as it will at least have a single application for all RGB devices if I plan to upgrade some components in the future. RGB control application for the Wraith Prism on Linux, Mac OS and Windows, written in Python and allows showing realtime CPU utilization.

Open-source Linux-only RGB control application for the Wraith Prism, written in Kotlin. RGB control application for multiple devices from diverse manufacturers. I found three options to control the RGB colors of Wraith Prism on a Linux platform:
