# Disabling the "\<Application> is not responding." System Message on Ubuntu

When running computationally heavy applications like Isaac Gym or Blender, it's common that the computation loop takes longer such that the application cannot meet Ubuntu's refresh time limit.

If this response deadline is missed, Ubuntu will show a pop-up window to notify the user, which is annoying.

## Solution

To address this issue, use the following command to either set the timeout to be longer, or disable the aliveness detection by setting the value to 0. The timeout value is in milliseconds.

```bash
gsettings set org.gnome.mutter check-alive-timeout 0
```

## Errata

In VSCode, it's possible to encounter the following error:

```bash
/snap/core20/current/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /lib64/libproxy.so.1)
Failed to load module: /home/untitled1/snap/code/common/.cache/gio-modules/libgiolibproxy.so
```

This is due to an artifact of VSCode from snap install, metioned in [this thread](https://github.com/microsoft/vscode/issues/180629). The solution is to uninstall vscode from snap store and install it from the Microsoft website .deb release package.

```
1. Removed the snap: `sudo snap remove code`

2. Downloaded the .deb package from the VSCode website.

3. Installed the .deb package: `sudo apt install ./<downloaded-file.deb>`
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://tk233.gitbook.io/notes/tools/ubuntu/disabling-the-less-than-application-greater-than-is-not-responding.-system-message-on-ubuntu.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
