Hi Rusty,

One problem we are having is that our application is crashing weston if the application is started when there is no active HDMI connection.  We see the error message "The Wayland connection broke. Did the Wayland compositor die?". We also see weston restart.

This definitely isn't a known issue.

However, if you are using a vendor BSP (e.g. NXP), they may have
substantially forked and changed Weston. In most cases, these bugs are
introduced by the vendor changes. If this is the case, please seek
support from your vendor, as unfortunately we can't support those
