<p class="MsoNormal">I am not sure this is the right place to post Wayland/Weston questions or report problems. If it is not, please forgive me and point me to the appropriate site.<o:p></o:p></p>
<p class="MsoNormal">Here is the problem that we face:<o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#26282A;background:white">The touchscreen on TI AM335x EVM is in reverse order, i.e starting from bottom-right instead of top-left.</span><span style="font-family:"Arial","sans-serif";color:#26282A"><br>
<span style="background:white">We were able to handle this at our QT5 Matrix-Gui application by setting the environment variable QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS="rotate=180" with QPA = EGLFS and LINUXFB.<o:p></o:p></span></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#26282A;background:white">However, this solution is no longer valid when we enable Wayland support on AM335x because the touch-screen rotation needs to be handled by the Wayland compositor.
It seems to us that Weston 1.9 does not support this kind of operation after a lot of Web searches.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#26282A;background:white"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Arial","sans-serif";color:#26282A;background:white">My question is whether Wayland compositor should support touch screen rotation and if the answer is yes, when will this feature be available? Attached please
find a hacking patch as a proof of concept only for your reference.<o:p></o:p></span></p>
