    Details

    • Platform/s:
      Linux/Wayland, Linux/X11

      Description

      For X11/XCB, only core keyboard device is supported now, see 

      https://github.com/qt/qtbase/blob/dev/src/plugins/platforms/xcb/qxcbkeyboard.cpp#L527-L543
      QXcbKeyboard::QXcbKeyboard(QXcbConnection *connection)
    : QXcbObject(connection)
{
    core_device_id = 0;
    if (connection->hasXKB()) {
        selectEvents();
        core_device_id = xkb_x11_get_core_keyboard_device_id(xcb_connection());
        if (core_device_id == -1) {
            qCWarning(lcQpaXcb, "failed to get core keyboard device info");
            return;
        }
    } else {
        m_key_symbols = xcb_key_symbols_alloc(xcb_connection());
    }

    updateKeymap();
}

      When user has multiple keyboard, expecially with different settings, it has issues.

      Haven't checked status on Wayland, but assume same now.
