Q Light Controller+

Can someone please let me know what video back end needs to be installed to use QLC+ on Linux? I have tried Debian, Arch, MX, Garuda, Kubuntu, other Ubuntu derivatives, and on and on. The only one on which QLC+ will play video on is Manjaro. All of the others present a blsck screen where video is supposed to be. And Manjaro isn't my first choice for Linux. Can someone please point me at what's missing? I've tried systems with ATI, Nvidia, and Intel video; I get the same thing every time.

Take a look to this post.

[moderator] please read the "community" section description before posting. It's definitely the wrong place to post a support request. Moving to the proper area.

This is the second time. Please spend some time to learn how to use a forum.

In fact I have your UltraDMX Max from the Dmxking.com and I'm trying to connect that with the the qlc plus the last version 4 it doesn't work and I tried the GIT version and doesn't work also in my Linux mint
I don't understand because it seems that the my laptop Hardware recognize the device but I cannot see that in the input output in the program there is any solution or anything would be much appreciated.
