displaylink not responding

I have lost so many hours over this. Thought I'd better just post on here, hoping smarter people see what I've been doing wrong.

After failing and giving up on trying to get a third monitor attached via usb-c to my asus rog g15 due to gpu hardware problems. I wanted to try and use usb to HDMI with displaylink. My init system is openrc.

I got evdi to work, which wasn't very straightforward, I had to use the developer version 'evdi-git' to make
Code: [Select]
sudo modprobe evdi
Work without any errors, but that does seem to work now.

Then I installed displaylink with
Code: [Select]
yay -S displaylink
To then run
Code: [Select]
/usr/lib/displaylink/DisplayManager
I was filled with excitement because after all of those wasted hours, I thought my monitor would receive a signal, but it didn't. It was completely unresponsive.
I tried changing some files like in /etc/init.d/displaylink
Couldn't get anything to work. I don't know what I'm doing wrong. My system is updated and seems to be fine. My hardware should be able to support this. And I have not forgotten to reboot and add the file in /etc/X11/xorg.conf.d/20-evdi.conf .

I am really at a dead and here, and if I can't get it to work I'll have to change operating systems which I don't want to do.
Thanks SO MUCH for your help.

In one of the threads you've mentioned this a user asked you to post your dmesg output. You didn't.

Hadn't seen it yet, but I now have given the adequate dmesg outputs. Also this wasn't what I mentioned, that was a seperate post about usb-c to hdmi not working. This is usb-a to hdmi. And someone else responded with a link to 'displaylink archwiki' which is what I've been trying to do but also doesn't get me anywhere.

I looked through 'sudo dmesg | grep usb", this is the full output;

I'm not seeing anything related to my vision usb-A to hdmi. It's a new expensive adapter, bought it just for this.
One weird behaviour; when I plug it in, my audio completely stops working, so it might be that my computer doesn't recognise it the way it's supposed to. But I have correctly installed the driver for it.

Any help is greatly appreciated. Thanks
