Odroid C2 Ubuntu (release 27/09/2017) OSD_GET_DMA_BUF_FD failed. (-1)

Hello @OtherCrashOverride ,

Thank you for the code. I'm trying to make it works on X11 (actually, fbdev got EGL_BAD_ALLOC when create surface as well). And I facing with error when get DMA buf for /dev/fb0 at https://github.com/nvl1109/CXVideoCube/blob/master/main.cpp#L623.
Here are output log:
