Appreciate your help to fix this issue

I guess when you start the docker image, xhost + is not executed.

Allow external applications to connect to the host’s X display:

xhost +

I executed xhost + and facing same issue

Are you running the command in ssh? Deepstream does not support x11-forwarding.

when you run the following command line, can you get output ?

echo $DISPLAY 

output from echo $DISPLAY


Please disable local x11-server .

After these, If you have plugged a display on your server, try export DISPLAY=:0 in your ssh.

If you don’t have a monitor, try modify nveglglessink to fakesink

when I setted DISPLAY=0
then run xhost +
it gives error as below
xhost: unable to open display “0”

What is the output of xrandr ?

Just set the value of DISPLAY to the screen index of xrandr output.

It’s 0/1 usually.

it didn’t work, so I changed pipeline to support filesink instead of display

Ok,Filesink or Fakesink will also work well in the pipeline.

If need further support,please open a new topic, Thanks.
