I have been trying to follow the directions on [Untethered Operation](https://docs.hello-robot.com/untethered_operation/) and got an error that seems to be related with OpenGL and OGRE.

After I succesfully ssh into the robot I tried the command:

> roslaunch stretch\_funmap mapping.launch

I’m going to paste the entire command line output later, but the bottom line is I get a warning with an exception:  
`[WARN] [1598989836.193298359]: OGRE EXCEPTION(3:RenderingAPIException): Unable to create a suitable GLXContext in GLXContext::GLXContext at /build/ogre-1.9-B6QkmW/ogre-1.9-1.9.0+dfsg1/RenderSystems/GL/src/GLX/OgreGLXContext.cpp (line 61)`

I looked a bit online and found [this in ROS Answers](https://answers.ros.org/question/10056/rviz-ogre-exception3renderingapiexception-unable-to-create-a-suitable-glxcontext-in-glxcontext/) (although that answer is from 2012) so I typed into my own computer’s terminal `glxinfo | grep version` and this was the output:

 ![issue_glxinfo](https://canada1.discourse-cdn.com/flex030/uploads/hello_robot2/original/1X/71e09417248885c1533d1abdfed45066729d8410.png)

This warning becomes an error after 100 tries  
`[ERROR] [1598990791.632950490]: Unable to create the rendering window after 100 tries. [INFO] [1598990791.632966605]: Stereo is NOT SUPPORTED terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid [INFO] [1598990791.671393091]: current scan mode: Boost, max_distance: 12.0 m, Point number: 8.0K , angle_compensate: 2 [rviz-16] process has died [pid 11132, exit code -6, cmd /opt/ros/melodic/lib/rviz/rviz -d /home/hello-robot/catkin_ws/src/stretch_ros/stretch_funmap/rviz/stretch_mapping.rviz __name:=rviz__ log:=/home/hello-robot/.ros/log/9e8b418c-ec8e-11ea-bb16-38002587e8f3/rviz-16.log]. log file: /home/hello-robot/.ros/log/9e8b418c-ec8e-11ea-bb16-38002587e8f3/rviz-16*.log`

Any help will be greatly appreciated 🙂

And here I’m pasting the entire output of the terminal up until the first warning of the ogre exception:

As a work around, I was able to set a remote master in my computer using our hostname and I can run rviz in my own laptop before I launch the funmap launch file. However, this results in rviz not having the same configuration

Hi @csemecu, it’s likely that “Unsuitable GLXContext” error is OpenGL complaining about being unable to start an X Window. The error after a 100 tries (`Unable to create the rendering window`) support this. It should be a simple fix. Since you’re running on Ubuntu, simple add a `-X` flag when ssh-ing into the robot. This allows Rviz to instantiate a renderable X window on your desktop through something called “X Forwarding”. So the command looks like:

```bash
$ ssh -X username@ip-address

```

By the way, I’m glad you were able to get around this using ROS remote master. I personally prefer to use remote master over X Forwarding anyways. The forwarded version of Rviz lags when manipulating the viewport since the computation takes place on the robot. In order to get the same Rviz configuration on my dev computer, I’ve set up a local version of the `stretch_ros` ROS package and `stretch_user` debug folder. If you’re interested in this setup, I’d be happy to add more information to the [Untethered Operation](https://docs.hello-robot.com/untethered_operation/) guide.

Hi @bshah, I am interested in “setting up a local version of the `stretch_ros` ROS package and `stretch_user` debug folder.” on my dev computer. How can I do that?

Thanks

Hi @burakaksoy, welcome to the forum! I’ve added information on how to do it to the same Untethered Operation, under the [Visualizing remotely with RViz](https://docs.hello-robot.com/untethered_operation/#visualizing-remotely-with-rviz) section. Let me know if you have any questions.
