SUMMARY I have hardware incapable of running wayland (proprietary drivers that only receive security updates). The device has a touchscreen with IMU correctly mapped and accessible with iio-sensor-proxy. Only wayland sessions have automatic device rotation available. STEPS TO REPRODUCE 1. use xorg session 2. see that automatic device rotation is not available EXPECTED RESULT autorotation is available in both xorg and wayland sessions SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 23.10 KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION I was able to find that @romangg was the author of the removal of orientationsensor from drm https://phabricator.kde.org/D26036 and then also addition to the kwayland backend https://phabricator.kde.org/R110:65585290f1098d401c19a645545bea93bf08f2e9
This is intentional right now; X11 development is not a priority and we are planning to switch to Wayland by default in Plasma 6.0.
