No EGL display error resolution

The version is as follows
CUDA edition ：10.2

tensorrt edition ：8.0.1.6

JetPack edition ：32.6.1

deepstream edition ：6.0

The system version adaptation diagram of the official website is as follows ：

Through comparison, we found that ： There is no problem with my version . So I began to check the error report carefully .

The first category reports an error
An error is as follows

nvbuf_utils: Could not get EGL display connection
No EGL Display
nvbufsurftransform: Could not get EGL display connection
No EGL Display

resolvent , Execute on the command line ：
unset DISPLAY
rm ${HOME}/.cache/gstreamer-1.0/registry.*

The purpose of entering the above command is ： take DISPLAY The value of the set :0.

You can enter the following command to view ：

echo $DISPLAY

# Output is :0

If the above command does not change DISPLAY The value of the set 0, Please use the following method ：

export DISPLAY=:0

Then enter the command again to see ：

echo $DISPLAY
# Output is :0

In fact, the first type of error reporting has been solved .

Input again ：

gst-inspect-1.0

It is found that the number of errors is reduced , But there is also 4 individual ：

It indicates that the first type of error reporting has been solved .

The second type of error report
