What means the “Failed to connect to server socket”?
the erros is below.
nvidia@tegra-ubuntu:~$ argus_multistream
Executing Argus Sample: argus_multistream
Failed to connect to Mir: Failed to connect to server socket: No such file or directory

How can fix this?
hello sensor_test,
had you tried below command yet?
export DISPLAY=:0
Why argus_multisensor can not find the camera?
nvidia@tegra-ubuntu:~$ ls /dev/video*
/dev/video0
nvidia@tegra-ubuntu:~$ DISPLAY=:0 argus_multisensor

Hi JerryChang,
Now I need display the “/dev/video0” video signal ,which program I can use?
I can launch the below two program,and no erros.maybe I need other program to test the drivers?
nvidia@tegra-ubuntu:~$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ming0522_003_009.raw

hello sensor_test,
there are several examples to access camera sensor, they were included in [Development Guide].
please download the [NVIDIA Tegra Linux Driver Package] and check [Release 28.2 Development Guide]
please refer to [Camera Development]-> [Camera Software Development Solution]-> [Approaches for Validating and Testing the V4L2 Driver]
