Aspherix® GUI cannot be launched on multi-gpu systems¶

On multi-gpu systems Aspherix® GUI may crash due to conflicts between different GLX versions.

For instance, you may get error messages like

qt.glx: qglx_findConfig: Failed to finding matching FBConfig for QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize -1, redBufferSize 1, greenBufferSize 1, blueBufferSize 1, alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile) Could not initialize GLX

To resolve this problem the following startup command tries to enforce the correct environment

QT_OPENGL=software LIBGL_ALWAYS_SOFTWARE=1 MESA_GL_VERSION_OVERRIDE=3.2 QT_XCB_GL_INTEGRATION=xcb_egl ./aspherix-gui
