Extending Monitor with an USB to HDMI Adaptor

Hello everyone,

I bought an adaptor usb to hdmi to connect other monitor but it seen i need to install the drivers. i was doing this guide step by step. but i got stuck when i do

xrandr --setprovideroutputsource 1 0

it’s supposed to work at this point and i could see the other monitor but instead i’m getting this output.

   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:  0x23f
  Serial number of failed request:  16
  Current serial number in output stream:  17

I’m on manjaro KDE/Plasma with the kernel 5.8.18-1

Thanks for reading
