So, i can provide further input, yet I'll still need help to understand how this works.
I can check the status of the connectors from the driver (using the command
Code:
#for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done)
This tell me that the /sys/class/drm/card1-DVI-I-1 corresponding to my displaylink device switch on and off (well connected/disconnected) when i plug/unplug the hub. All fine there.
Still, i can't have it connected using xrandr.
Any help or Idea is welcome.
Regards,
Marc
