docker里執行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執行 “xdpyinfo | grep name”得到一個數字，例如?name of display: :1，再執行? "export DISPLAY=:1 ",最后執行?"xhost + ", 正確的打印是 “access control disabled, clients can connect from any host”.
