glsanity

Absence of 32-bit OpenGL libraries on 64-bit Linux distributions or mismatch between OpenGL client library and Xorg GLX module implementations on systems using proprietary OpenGL drivers is a well-known source of problems.

'glsanity' aims to help in diagnosing such problems by providing a few test programs in one package.

Both 32-bit and 64-bit tests are included with prebuilt binaries. To download, navigate to releases page and grab the glsanity-bin.zip file.

Most users should run the ./glsanity script. Users of laptops with hybrid graphics using Bumblebee and primus for offloading can use ./glsanity-bbee.

What is tested

The following tests are performed:

  • What OpenGL library (libGL.so.1) is loaded by default
  • That GLX extension is available on the X connection
  • That direct rendering is available

The last test also tries to detect software rendering by matching GL_RENDERER for 'llvmpipe' and 'Software' (for Mesa swrast).

Sample output

NVIDIA drivers, Gentoo
