I started up the X1 and flashed the GUI as instructed, so I have the GUI working.
I next downloaded JetPack-L4T-2.0-linux-x64.run from the JetPack site, and followed the instructions at
ubuntu@tegra-ubuntu:~/Downloads$ chmod +x JetPack-L4T-2.0-linux-x64.run
Creating directory _installer
Verifying archive integrity… All good.
Uncompressing JetPack 100%
Nothing else happens – there is no GUI window as shown in the docs page. I looked in the _installer directory, but I don’t see a obvious README or a setup file.
Looking at the .run file, a lot more should be happening, but it’s not.
