<pre>In multi display setup, when calibrating secondary display with touch device,
touch doesn’t not work. If I disconnect primary display, that makes secondary
display as new primary display and touch works just fine.
Steps to reproduce:
1. Identify primary display as display1, and secondary display as display2.
Here secondary display is a touch device.
2. Launch weston
3. Execute weston-calibrator on display2 and capture calibration values
4. Exit weston
5. Create a udev rule in /etc/udev/rules.d/weston.rules with calibration
values:
Example:
ENV{ID_VENDOR_ID}=="2149",ENV{ID_MODEL_ID}=="2122",ENV{WL_CALIBRATION}="0.994876
-0.013934 12.975220 -0.004180 1.008462 -3.079773"
(I tried udev rule with LIBINPUT_CALIBRATION_MATRIX, touch does not work.
Weston still using WL_CALIBRATION, I created udev rule with WL_CALIBRATION)
6. Unplug and replug touch device
7. Restart weston.
8. Execute weston-simple-touch on display2. Observe touch does not work.
9. Disconnect display1. Observe touch works on display2.
