  1. 按照官方文档修改了了/etc/profile.d/weston.sh中的export WESTON_DRM_MIRROR=1；
  2. 接入RK3588两个HDMI显示器后，使用QT获取了创建了2个widget，按照获取到的两个屏幕的坐标进行布局；但是2个widget同时布局到2个屏幕上

qt操作

QList<QScreen *> screenList = QGuiApplication::screens();
    foreach (auto screen, screenList)
    {
        qDebug()<<screen->name();
        if (screen->name() == P_HDMI_NAME_STR)
        {
            if (m_hdmiPanel == nullptr)
                m_hdmiPanel = new HdmiPanel(nullptr);

            m_hdmiPanel->setGeometry(screen->geometry());
            m_hdmiPanel->setWindowState(Qt::WindowFullScreen);
            m_hdmiPanel->setWindowTitle(P_HDMI_NAME_STR);
            m_hdmiPanel->show();
        }
        else if (screen->name() == P_EDP_NAME_STR)
        {
            if (m_edpPanel == nullptr)
                m_edpPanel = new EdpPanel(nullptr);
            m_edpPanel->setGeometry(screen->geometry());
            m_edpPanel->setWindowState(Qt::WindowFullScreen);
            m_edpPanel->setWindowTitle(P_EDP_NAME_STR);
            m_edpPanel->show();
        }
    }
    QObject::connect(qGuiApp, &QGuiApplication::screenAdded, this, &AppManage::screenAddedSlot);
    QObject::connect(qGuiApp, &QGuiApplication::screenRemoved, this, &AppManage::screenRemovedSlot);
