Description U. Artie Eoff 2013-12-18 19:33:21 UTC 
Weston does not seem to honor WL_OUTPUT setting in udev rules anymore.  When WL_OUTPUT is specified, WAYLAND_DEBUG does not indicate any touch events occur when touching the device.  However, if I remove the WL_OUTPUT directive from the udev rules, WAYLAND_DEBUG shows touch events.

Reproduced with the following setup:

A calibrated single touchscreen device plugged into VGA1.

The weston log shows messages:

while occasionally getting a wl_touch@29.up(4, 120806958, 0) event.

Seems to work fine with a multitouch device
Comment 5 U. Artie Eoff 2014-01-07 17:07:55 UTC 
Root caused this issue to a faulty single-touch display device.
