I have QLC+ (Q Light Controller plus) working on well on a Linux laptop with a £35 dongle labeled DimTech (*) which uses open source software. Worked straight out of the box. (*) TITLE = DimTech USB to DMX Stage Lighting USB-DMX DMX512 Dimmer open Enttec Controller (**) As at Friday 13th Dec 2019 this ebay listing is the one I bought from ... EBAY LINK I have searched for the solution myself and I am in the same situ. I have a Jester 48 which works really well (48 chanels max), however I am now finding, with multi chanel LED fixtures, I am running out of channels really quickly, so I might go down the QLC+ on Linux route. Good luck
