Hi,

it looks like you are using a properietary graphics stack. We at weston
upstream cannot help you with that, because I assume the source code is
not public.

A wild guess: could it be that your system loads some graphics
(kernel?) drivers in parallel, and when weston is first attempted, the
driver has not loaded yet?


Thanks,
pq
