One of the biggest complaints about RGB is the software ecosystem surrounding it. Every manufacturer has their own app, their own brand, their own style. If you want to mix and match devices, you end up with a ton of conflicting, functionally identical apps competing for your background resources. On top of that, these apps are proprietary and Windows-only. Some even require online accounts. What if there was a way to control all of your RGB devices from a single app, on both Windows and Linux, without any nonsense? That is what OpenRGB sets out to achieve. One app to rule them all.
I have a Logitech G213 gaming keyboard, and a Logitech G203 gaming mouse, and the program as installed from the software manager of Linux Mint 21.2 works perfectly for my devices.
Works really well once you set the udev rules correctly. It's incredible to think that it is not an official software from any brand. I only have one complain. The software detects my keyboard (CorsairK68) and I'm able to edit the led of every key except for 2. Volume up and volume down. I find it a bit weird.
I used the 'Linux (Debian Bookworm 64-bit .deb)' version 0.8 package from the official site, https://openrgb.org/releases.html, on Mint 21.1, worked perfectly. Not much of a fan of Flatpaks, etc. Still giving it a 5 for the software.
"Linux (Debian Bookworm 64-bit .deb)" from https://openrgb.org/#downloads worked for me (Linux Mint 21.1 "Vera")
EDIT: Please follow SandyCohen advise to make OpenRGB work in Linux Mint 20.3 as it is better than as I originally suggested, still, it is not optimal having to manually download and drag and drop a file out of a Gitlab link for an application available in Software Manager to make it function properly. The application works fine but it is still visually bare bones.
SciFiCat: this is not the way to go. Launching it with sudo leads to other issues, such as not being able to install plugins. When installing with flatpack, simply download the udev rules file and place it in the corresponding folder, as mentioned on the gitlab. Go check it out for details. "https://gitlab.com/CalcProgrammer1/OpenRGB" Version 0.7 works on Mint 21 directly from Flatpak (I saw some comments suggesting otherwise). They must have fixed the problem. The issue I'm facing is that Openrgb won't recognize aRGB RAM (kingston fury ddr5). Even after all the i2c and grub update shenanigans (Gigabyte mobo). That and the fact that the interface seriously needs a designer :) Therefore 3
If you want it to actually work, do not download it from here, go to " https://openrgb.org/#downloads " and download and install "Linux (Debian Buster 64-bit .deb)"
The only version that works is the .deb
