QT5.1.5+linux Arm qt.qpa.wayland: qtvirtualkeyboard currently is not supported at client-side, use QT_IM_MODULE=qtvirtualkeyboard at compositor-side.

我写了一个QT程序，我使用QT自带的虚拟键盘，qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));但是我一点击输入框，键盘一闪就不见了，运行项目的时候还报错qt.qpa.wayland: qtvirtualkeyboard currently is not supported at client-side, use QT_IM_MODULE=qtvirtualkeyboard at compositor-side.，我在arm设置环境QT_IM_MODULE=qtvirtualkeyboard也不生效，请问我需要更改虚拟键盘的源码吗
