We are trying to setup multi-seat on IVI box VTC1010. We manage to setup two seats (seat0, and seat1) using tlm (and some modifications to udev rules file for seat; please see end of email). 

In this context, we came across couple of questions:

1- Who should be "master of seat" as it is mandatory? we have set usb-hub as master-of-seat.
2- How could separate monitor be attached to a seat (as one is connected on VGA and other on DP)? we have done that using weston.ini but it does not seem to work.


- Two usb hubs connected to usb port 1 (front) and port 2 (back)
- Each usb hub has mouse and keyboard connected (one of them also has USB mass storage which contains the IVI image)
- One screen is connected to DP
- Another screen is connected to VGA




/usr/lib/udev/rules.d/71-seat.rules (added following lines as per two usb hubs)
SUBSYSTEM=="usb", ATTR{idVendor}=="05e3", ATTR{idProduct}=="0608", ENV{ID_AUTOSEAT}="1", ENV{ID_SEAT}="seat0", TAG+="master-of-seat"
SUBSYSTEM=="usb", ATTR{idVendor}=="1a40", ATTR{idProduct}=="0101", ENV{ID_AUTOSEAT}="1", ENV{ID_SEAT}="seat1", TAG+="master-of-seat"
