Failed to open /opt/ros/noetic/share/rviz/default1.rviz for writing

[sdanie20]

Hello, I am currently working on Unit2 and am facing this error when I try to save the config.
I even tried saving to a new file called default1.rviz and it still says it couldn’t open that file.

Hi @sdanie20 ,

Welcome to this Community!

You cannot save on the /opt/ros/noetic/share/rviz/ as you will not have read-write permissions to that folder. [That said, do not try to give read-write permissions to this directory!]
So you must save your rviz config file in your own workspace path or in your ROS package directory.

I hope this solves your problem.

Thank you. This worked for me. But I have to go and open that specific config file every time. Is there a way to change the default location and .rviz file that loads?

Hi @sdanie20 ,

@sdanie20

Is there a way to change the default location and .rviz file that loads?

Yes, you can do it in two ways.

1. Command line on terminal:

rosrun rviz rviz -d /path/to/config.rviz

2. Using launch file:

<node pkg="rviz" type="rviz" name="rviz" args="-d $(find <your_pkg_name>)/path/to/config.rviz"/>

Add the above line to your launch file.
