Qt5_CinematicExperience -platform eglfs

result:

QEglFSImx6Hooks will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.

If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

Could not open egl display

then i set FB_MULTI_BUFFER=2 or QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1

result:

root@imx6qsabresd:~# Qt5_CinematicExperience -platform eglfs

Could not open egl display
