Hi,

this is my situation:

deepstream-app version 5.0.0
DeepStreamSDK 5.0.0
CUDA Driver Version: 10.2
CUDA Runtime Version: 10.2
TensorRT Version: 7.0
cuDNN Version: 7.6
libNVWarp360 Version: 2.0.1d3

I pull the nvidia docker: nvcr.io/nvidia/deepstream:5.0.1-20.09-triton in nvidia V100

cd /opt/nvidia/deepstream/deepstream-5.0/samples/configs/deepstream-app
export DISPLAY=":0"
deepstream-app -c source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

then it prints:

No protocol specified
No protocol specified
No protocol specified
No protocol specified
No protocol specified
No protocol specified
** ERROR: <main:655>: Failed to set pipeline to PAUSED
Quitting
App run failed

then i run xrandr

it prints:

No protocol specified
Can't open display :0

how can i fix this problem?

Same issue with this topic.

it works on the morning, but i don’t know why this problem comes again afternoon and can you see the way to fix it from the result of xrandr?

Please try export DISPLAY=":0" before run the docker. and add option when run docker, -e DISPLAY=$DISPLAY
