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.
Judging by your commands, I will assume you are attempting to run JetPack on your Jetson. While the (T)X1 is a 64 bit processor, it is a 64 bit ARM processor.
JetPack (as far as i know) is meant to be run on a linux host (x86 or AMD64/X86-64, like nearly any current laptop or desktop), Not on the Jetson itself.
As far as I could tell, JetPack needs to run on 64bit (amd64) Ububtu 14.04. The binaries are 64bit and won’t run on the 32bit (x86) flavor of Ubuntu 14.04.
JetPack is a host development system tool to help deploy and develop for Jetson Development Kits, so at this time, JetPack only supports running on Ubuntu 14.04 x64 host system.
Running JetPack on a Jetson Development Kit with L4T is not an expected use case.
