Jetson Nano no display: nvbuf_utils: Could not get EGL display connection

peeranat85 · August 1, 2022, 10:44am

Hi,

I realized this issue has been in other threads too but I didn’t find any that solved in my environment so I decided to post mine here.

I’m running Jeson Nano without connecting to the display. When I ssh’ed to Jetson Nano from my laptop and ran deepstream-test1, I got display error. Here’s the steps to reproduce.

ssh to the device and go to deepstream-test1 directory.
run sudo CUDA_VER=10.2 make
run

aaeon@aaeon-desktop:/opt/nvidia/deepstream/deepstream/sources/apps/sample_apps/deepstream-test1$ ./deepstream-test1-app /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264 
nvbuf_utils: Could not get EGL display connection
nvbuf_utils: ERROR getting proc addr of eglCreateImageKHR
nvbuf_utils: ERROR getting proc addr of eglDestroyImageKHR
One element could not be created. Exiting.

I then modified the sink element to be fakesink to bypass the display issue. But, I got the same error. After some investigations, I set DISPLAY=:0 as suggested in other threads but still didn’t work with the same error.

I then tried the following and still got the same error

Finally, I reinstalled deepstream-6.0 following Quickstart Guide — DeepStream 6.0 Release documentation but the same error still appeared.

Environment
HW: Jetson Nano
DeepStream version: 6.0 from https://developer.nvidia.com/deepstream-6.0_6.0.0-1_arm64deb
JetPack version: 4.6-b199
Issue Type: Question

Which terminal client you are using? putty or something else? Did you enable X11 forwarding? if yes, please disable it.
and try unset DISPLAY and run app again in case you change the sink to fakesink.

peeranat85 · August 2, 2022, 7:51am

I’m using ssh command on Ubuntu. X11 forwarding already disabled. DISPLAY already unset.

Amycao · August 3, 2022, 9:20am

How about reopen the terminal and run again?

peeranat85 · August 3, 2022, 11:33am

tried. it didn’t work. When I ran in docker image nvcr.io/nvidia/deepstream-l4t:6.0-base it didn’t show this error. I suspect it has something to do with the installed packages? i tried reinstalling deepstream from https://developer.nvidia.com/deepstream-6.0_6.0.0-1_arm64deb but still got the same error.

peeranat85 · August 9, 2022, 8:41am

@Amycao may I ask for an update on this?

Amycao · August 11, 2022, 8:01am

If you do not have monitor connected to device, set DISPLAY=:0 did not help. are you sure you make change of sink type set to fakesink success? How about clean the cache, and rerun again?
rm ~/.cache/gstreamer-1.0/ -rf

Since you are running on Jetson, if you disable nveglglessink, you need to disable nvegltransform also.

peeranat85 · August 11, 2022, 10:42am

rerunning all the above steps, I got the same error

I run on Xavier JP 4.6, Deepstream 6.0, with your app, it work fine.
From your log, there argus error, why you got this error, there no arguscamerasrc plugin in test1 app. seems your environments issue.

peeranat85 · August 15, 2022, 6:58am

@Amycao Thanks for your response. I think it’s an environment issue too. I tried restalling DeepStream and GStreamer but still didn’t work. I guess I’d have to flash the microSD card? Do you have any other option?

Amycao · August 16, 2022, 9:38am

Suggest you do a fresh installation including bsp and deepstream.

peeranat85 · August 16, 2022, 5:47pm

@Amycao thank you. Btw, What do you mean by bsp?

Amycao · August 17, 2022, 4:59am
