If you really need to do some basic sanity checking and verify that libGL / libX11 aren't totally broken, you could do something like autoconf does and run a small, trivial GLX test program before your main app. You could invoke the test program from a shell script wrapper (or maybe from in the main app via fork/exec). Check if the test program exits abnormally, and disable OpenGL if needed.
