qtchooser --print-env结果如下：
QT_SELECT=“default”
QTTOOLDIR=“/usr/lib/x86_64-linux-gnu/qt4/bin”
QTLIBDIR=“/usr/lib/x86_64-linux-gnu”
sudo gedit /usr/lib/x86_64-linux-gnu/qtchooser/default.conf
把里面的qt4换成qt5试试
我用的是UK 17.10版本，修改的是sudo gedit /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf
还是不行
UK 下有没有可用的WIFI网络手机投屏软件？
改这个文件不行啊，你看改完后，qtchooser -print-env 输出应该还是qt4
不太了解， Vysor， Teamviewer?
在哪下的，我试试
