Hello, community!

I am a beginner who has just started using this tool.
I hope you can be patient with me.

While working on this tutorial Lab (FPGA Flow Tutorial), I encountered the following issue:

🚨 Issue

When I run the following command:

vivado finn_vivado_stitch_proj.xpr

I receive this response:

What should I do?

🔍 My Attempts

I tried 2 different methods:

1️⃣ Running Vivado as root in a Separate Terminal

I opened another terminal and switched to root.
Then I ran:

vivado finn_vivado_stitch_proj.xpr

Result: It worked! ✅

However, this terminal was not opened inside the Docker container.
💡 Question:
Would this method cause any issues? Or is this the way everyone runs it?

2️⃣ Setting the DISPLAY Environment Variable Inside the Container

I followed a method suggested by ChatGPT and ran:

export DISPLAY=:0

Then I tried running Vivado again:

vivado finn_vivado_stitch_proj.xpr

Result:

it fails with missing libXtst.so.6 and JVM errors.

How can I resolve this issue?
Is there an alternative way to run Vivado GUI inside the container?

Last Question:

The FINN script ./run-docker.sh starts a container that allows saving files.
Can I later restart this container using docker start xxxxxxxxxxxx,
or am I only able to restart it using ./run-docker.sh?

I appreciate any help or suggestions! 🙏 Thank you in advance! 🚀
