Ensure that your host machine has an X server installed. For Windows, you can use vcxsrv. For macOS XQuartz. On most Linux Distributions, you likely already have an X server.
On your host machine, ensure that you launch your X server. On Windows you may need to create an environment variable named DISPLAY with the value "127.0.0.1:0.0" and restart. Then, execute the following to enable X-forwarding:
$ ssh -XY wes-237b@192.168.55.1
If you are using PUTTY instead, ensure that you have enabled X-forwarding under your SSH options.
An alternative option on Windows is to use MobaXterm, which allows you to graphically configure both the X server and the SSH connection.
To test your X-forwarding, you can run gedit.
It is additionally possible to use X-forwarding in Visual Studio Code. To do so edit ~/.ssh/config and update your entry for the Jetson to match the following, then restart Visual Studio Code.
Host 192.168.55.1
HostName 192.168.55.1
ForwardX11 yes
ForwardX11Trusted yes
