Hi Sir ,

We are using weston (1.9.0) for loading our application on IMx6Q sabreauto board.
sometimes it fails to start and sometime it works after reboot or after restart Weston services.
I found that there is some synchronisation issue occurred in loading western service at the boot time.
A log file (/var/log/weston.log)is mentioned in the western-start script file .
Form the log file I get the details about error like below

Date: 2018-02-09 UTC

Western or Weston? I never saw anything as western, considering GFX
(you mentioned western twice)?! Probably you meant Weston.

Weston is Wayland backend, actually, Wayland is more of a GFX
communication protocol, and Weston is one of the several compositors
behind Wayland. Other well-known compositor is Mutter, as common
example.

It seems that you have timing synchronisation problem (race effect)
between EGL's (Embedded Graphic Library) loadable modules components,
and the best place to ask about such things is exactly:
http://wayland.freedesktop.org
Bug reports to:
https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=1.9.0

Best Regards,
Zoran
