Hi Sam, This means your computer's OpenGL driver is not adequate. You will need to update or install an OpenGL driver to get ChimeraX to work. Tom

Hello,

I have an issue starting ChimeraX_1.3 for ubuntu20.04. "chimerax" command gives the following:

NOTE: available bundle cache has not been initialized yet NOTE: Updating list of available bundles failed: Internal Server Error WARNING: WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed. WARNING: QGLXContext: Failed to create dummy context ERROR: Could not create OpenGL context BUG: Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples 0, swapBehavior QSurfaceFormat::DefaultSwapBehavior, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile) Aborted (core dumped)

Any advice please?

Best, Sam
