By default enabled but one can disable it by passing --disable-xwayland-test to the configure script. Also, the weston-tests-env script is trying to load xwayland.so in either case, but it behaves resilient in the absence of that meaning all the other tests are still going to be kicked for running.

* Ideally, the X Window Manager (XWM) and Weston Wayland compositor shouldn't

|
|
* request for Weston process it. X is blocked. At the same time, XWM might be
|
|

|
|
* the X server (xcb_get_property_reply -> xcb_wait_for_reply) which therefore
|
|
