 These libGL errors are from Mesa libGL, which is trying to use the userspac= e part of nouveau (which is part of the Mesa project),
presumably based on Nvidia GPU's PCI ID being known to Mesa, despite th= ere being no nouveau kernel interface available.

Since I'm trying to use Nvidia's binary driver (the only one which = works on FreeBSD), Blender should have never loaded Mesa's libGL in the=
first place - there is most likely a configuration problem here with=20 libglvnd, the component responsible for choosing the correct libGL
implementation.

When Blender fails to detect CUDA this has nothing to do with libGL and abs= olutely nothing to do with nouveau.

Smplayer behaves t= he same as blender. I think this is a general=20 behavior. Check below what happens when I run it within the linuxulator :
