已经移植qt5.12到hi3559a,  eglfs模式下可以正常显示qt的样例程序，但是鼠标不显示。 鼠标在开发板上存在，位置在/dev/input/mouse0, 同时/dev/input/event0也存在。 按照qt移植文档，没有使用libinput而是依赖默认的libudev 请大佬推荐一下排查思路。 qt configure的结果如下： Build options:   Mode ................................... release   Optimize release build for size ........ no   Building shared libraries .............. yes   Using C standard .......................
