I suppose that was solved years ago

Unfortunately, I have not used this software for several years. I can't
say if it works at the moment.

Mesa lumps all of its drivers together under one vendor named "mesa"
so you are supposed to be able to do something like this:
DRI_PRIME=1 __GLX_VENDOR_LIBRARY_NAME=mesa glxinfo | grep vendor
Unfortunately, Mesa doesn't like something about the GLX fbconfigs the
NVIDIA driver provides, so it doesn't actually work:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
Major opcode of failed request: 152 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 62
Current serial number in output stream: 61

I see. I tried the following:
~$ __NV_PRIME_RENDER_OFFLOAD=0 __GLX_VENDOR_LIBRARY_NAME=i965
glxinfo|grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation
~$ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=modesetting
__GLX_VENDOR_LIBRARY_NAME=i965 glxinfo |grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation
~$ __NV_PRIME_RENDER_OFFLOAD_PROVIDER=modesetting
__GLX_VENDOR_LIBRARY_NAME=i965 vainfo
libva info: VA-API version 1.8.0
libva info: Trying to open /usr/xorg/lib64/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
No matter what I try, it always defaults to nvidia.
Maybe I'm doing something wrong?
Thanks!
