Many hardware developers sadly don't provide official drivers for Linux, even when they do there's no decent interface for them. One user got "sick" of Razer's "lack of Linux support for laptops" so they made their own driver.
The Razer Laptop Control Project was created from this, with a focus on Razer laptops fan and power mode modifications and to eventually do everything Razer Synapse does but on Linux. While there is already Openrazer, that has a focus on the RGB lighting. We may also see RGB controls being added to this project too, according to what the developer has said. They've already been able to recreate Razer's "ambient RGB mode", which they showed off in a video and it actually looks very cool:

Fantastic to see the community build up drivers where the official vendor has not, like with CM-RGB for controlling the AMD Wraith Prism RGB colouring on Linux.
It's amazing what some people can do.
