log of weston trying to start on a udl/displaylink device

Hi

I am trying to see if I can start weston on a udl/displaylink 2.0 device
I blacklisted the udlfb driver, in favor of udl, as it has Kernel Mode Setting,
and I am trying to test multiseat abilities in Weston.

While it seems the device is working, starting Weston, the screen never lights
up. (this might be an issue with the driver??, although the edid is in sysfs.
If there is a way to light up the display, and run Weston again...)


It seems that in the log, it states 'bo is out of bounds', and then it exits
for some reason, (could be because the screen is off?, Weston does run for a
little bit, after the warning...)

I attempted to attach the built in video device to seat1 for now, and start
weston with
weston --seat=seat0
for now

I have the full log attached

Thanks
