(I vaguely remember this occurring sometime between Wheezy and Stretch but didn't really pay it much attention at the time). Installation of the proprietary 304xx nvidia driver (in Stretch as no longer included since Buster) changes but does not fix the issue. > > I get the impression it's something to do with the spaghetti of openGL symbolic links, but I'm a little out of my depth. > > Would love to get some help to rectify this one way or another. > Good day David, (well, day with a lot of noise, but that is relatively uncommon actually), Last time I had some garbling with libgl links, it was due to a reinstallation, or update, of "xorg-xserver", which erased an NVidia specific version of the libgl.so with its own. Could you send the output of the following commands: $ glxinfo | head $ nvidida-smi $ lspci | grep VGA Well, assuming the problem does come from garbled OpenGL libs, purging then reinstalling the NVidia driver might help, but I am referring for myself to a situation where the .run file from NVidia was in use (specific driver qualification in professional context); not sure how things would work with Debian packaging.
