KDED module for handling automatic screen rotation on X11, with visual feedback before orientation change happens. Some assembly might be required.
Run ./install_kded_rotation.sh and install missing dependencies as needed. To start the service, you will need to restart your current session or reboot.
You'll most likely need qt5-qtbase-devel, cmake-utils, extra-cmake-modules, iio-sensor-proxy, xrandr, qt5-qtsensors and kf5-kded-devel. Depending on your distribution, these packages might have different names. CMake will tell you which packages it is missing.
On kubuntu run sudo aptitude install build-essential cmake extra-cmake-modules libqt5sensors5-dev kded5-dev
orientation-helper is where the actual screen rotation happens. This is achieved by calling xrandr --rotation $value, which works in most circumstances. You can adjust orientation-helper to fit your setup and reinstall to apply.
To reduce or increase the timer before the rotation happens, adjust timer.start(25); in screenrotator.cpp:
void ScreenRotator::startProgress() {
if (progress == -1) {
timer.start(25);
progress = 0;
}
}If your touchscreen does not change orientation, you can show your input devices with xinput list and copy the name of your touchscreen controller, then edit /usr/bin/orientation-helper (or type whereis orientation-helper to get the right path)
IS_TOUCH=$(echo $props | grep -i 'name_of_your_touch_controller_here')
save and restart the session to apply.
