A basic rendering check using the PyMol molecular viewer. You must be using a card supported by the Radeon video driver.
How to test
- Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to suceed)
- Ensure that `glxinfo
- all the demoes should run without crashing or obvious misrenderings (flickering, surfaces that come and go...)
