Hi! I am a beginner in Linux and I have recently installed Manjaro with i3. I want to make a dual monitor setup, so I bought a dell d3100 with DisplayLink but I have problems making it work.
I followed the instructions here:
-wiki.archlinux.org/title/DisplayLink
I get stuck at the last step:
xrandr --setprovideroutputsource 1 0
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)
Value in failed request: 0x7cb
Serial number of failed request: 16
Current serial number in output stream: 17
But I suspect that the fail is in the previous step, I do have 2 providers, but the second is not a “Sink Output” like in the article.
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x44 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:modesetting
Provider 1: id: 0x7cb cap: 0x5, Source Output, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:modesetting
Tried to find a answer but with no success. I suspect that it might be something with the kernel or headers, but I don’t really understand what that is. I will post commands bellow that might give a clue. Would really appreciate help!

I tried to follow this guide, and now this folder looks like this:
