Install JTOP
<pre>sudo apt install python3-pip</pre>

After pip installs:

<pre>sudo pip3 install -U jetson-stats</pre>

Install jetson containers
<pre>
# install the container tools
git clone https://github.com/dusty-nv/jetson-containers
</pre>
The opencv_install.sh has gone so you must recreate it using:
<pre>
cd jetson-containers/packages/opencv
nano opencv_install.sh
</pre>
Then paste the following into the sh file:
<pre>
#!/bin/bash
#

version="4.10.0"
folder="workspace"

set -e

for (( ; ; ))
do
echo "Do you want to remove the default OpenCV (yes/no)?"
read rm_old

if [ "$rm_old" = "yes" ]; then
echo "** Remove other OpenCV first"
sudo apt -y purge *libopencv*
break
elif [ "$rm_old" = "no" ]; then
break
fi
done

echo "------------------------------------"
echo "** Install requirement (1/4)"
echo "------------------------------------"
sudo apt-get update
sudo apt-get install -y build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev python3.10-dev python3-numpy
sudo apt-get install -y libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libv4l-dev v4l-utils qv4l2
sudo apt-get install -y curl

echo "------------------------------------"
echo "** Download opencv "${version}" (2/4)"
echo "------------------------------------"
mkdir $folder
cd ${folder}
curl -L https://github.com/opencv/opencv/archive/${version}.zip -o opencv-${version}.zip
curl -L https://github.com/opencv/opencv_contrib/archive/${version}.zip -o opencv_contrib-${version}.zip
unzip opencv-${version}.zip
unzip opencv_contrib-${version}.zip
rm opencv-${version}.zip opencv_contrib-${version}.zip
cd opencv-${version}/

echo "------------------------------------"
echo "** Build opencv "${version}" (3/4)"
echo "------------------------------------"
mkdir release
cd release/
cmake -D WITH_CUDA=ON -D WITH_CUDNN=ON -D CUDA_ARCH_BIN="8.7" -D CUDA_ARCH_PTX="" -D OPENCV_GENERATE_PKGCONFIG=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-${version}/modules -D WITH_GSTREAMER=ON -D WITH_LIBV4L=ON -D BUILD_opencv_python3=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make -j$(nproc)

echo "------------------------------------"
echo "** Install opencv "${version}" (4/4)"
echo "------------------------------------"
sudo make install
echo 'export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
echo 'export PYTHONPATH=/usr/local/lib/python3.10/site-packages/:$PYTHONPATH' >> ~/.bashrc
source ~/.bashrc

echo "** Install opencv "${version}" successfully"
echo "** Bye :)"
</pre>

Now either run the bash file above which will install OpenCV.4.10.0 ...
<pre>
bash opencv_install.sh
</pre>

Or if you want a specific version of OpenCV then compile opencv as below
Change into the home directory
<pre>
sudo ./jetson-containers/packages/opencv/opencv_install.sh https://nvidia.box.com/shared/static/ngp26xb9hb7dqbu6pbs7cs9flztmqwg0.deb OpenCV-4.8.1-aarch64.tar.gz</pre>

Run JTOP and you should see

Simon:

You will need a GNOME Shell extension to solve this problem.

First, install install gnome-shell-extension-manager with this command:

<pre>sudo apt install gnome-shell-extension-manager</pre>
The open the newly installed app called Extension in the GUI. Within this app, search for Jonathan Kamens and install the Allow locked Remote Desktop GNOME Shell extension.

Now you will be able to remotely connect to this computer even when the screen is locked. You will still need to be logged in locally first.
