deepstream 问题

docker里执行gst-inpect-1.0  nvinfer

# No EGL Display
nvbufsurftransform: Could not get EGL display connection
MoTTY X11 proxy: Unsupported authorisation protocol
No EGL Display
nvbufsurftransform: Could not get EGL display connection
No such element or plugin 'nvinfer'

分析： 得不到xserver的支持，要用headless模式，用本地terminal执行 “xdpyinfo | grep name”得到一个数字，例如 name of display: :1，再执行  "export DISPLAY=:1 ",最后执行 "xhost + ", 正确的打印是 “access control disabled, clients can connect from any host”.
