Glxinfo

Glxinfo: Utility for Displaying OpenGL and GLX Extension Information

A utility for displaying information about OpenGL and GLX extensions, reporting version numbers, GPU information, listed OpenGL extensions and capabilities.

What is Glxinfo?

Glxinfo is a tool used to get information about the OpenGL implementation on a system. It can provide details such as:

• Version of OpenGL supported
• Version of GLX
• Vendor and renderer of the OpenGL driver
• List of OpenGL extensions supported
• Information about OpenGL capabilities like max texture size, number of texture units, etc.

Glxinfo is very useful for debugging OpenGL applications, ensuring you have proper OpenGL support on a system, and just generally learning about the OpenGL implementation. It's a simple command line tool that is easy to run. Typical output contains the OpenGL vendor, renderer, version, shader support, texture capabilities, and extension list.

Some examples of how Glxinfo can be useful:

• Verify that the latest OpenGL version is supported before developing/running an app.
• Ensure hardware acceleration is being used for OpenGL.
• Check for support of a specific OpenGL extension.
• Get GPU details like VRAM, vendor, rendering engine.
• Troubleshoot graphics/OpenGL problems by comparing OpenGL capabilities.

As an open source command line tool, Glxinfo is included in many Linux distributions and other operating systems with OpenGL support. It provides a simple way to get key technical details about the current OpenGL environment on a system.
