--- Comment #17 from Pierre Ossman <ossman at cendio.se> ---
So I found the code that handles this:

https://github.com/NVIDIA/libglvnd/blob/470fc824a38521a52707c6c0f59d827aa5e0f45a/src/GLX/libglxmapping.c#L519-L600

And "indirect" is indeed a poorly named fallback.

It also reveals that the required magic is not the GLX version, but rather a
GLX extension. Which unfortunately wasn't added until xorg-server 1.19. So all
but the latest fails to support this new mechanism.

In that case, is there any compelling reason why the fallback shouldn't always
be mesa?
