Repro Steps

Steps were followed from here
sudo apt install mesa-utils
nvidia-smi
MESA_D3D12_DEFAULT_ADAPTER_NAME=NVIDIA glxinfo | grep "OpenGL renderer"

Expected Behavior

The following output should be present:

MESA: error: ZINK: failed to choose pdev
glx: failed to create drisw screen
OpenGL renderer string: D3D12 (NVIDIA GeForce RTX 4060 Laptop GPU)

Actual Behavior

The following output is given by running the glxinfo command as outlined in "Repro Steps":

MESA: error: ZINK: failed to choose pdev
glx: failed to create drisw screen
OpenGL renderer string: llvmpipe (LLVM 17.0.6, 256 bits)

Running the same command without the env variable gives the following:

MESA: error: ZINK: failed to choose pdev
glx: failed to create drisw screen
OpenGL renderer string: D3D12 (Intel(R) Arc(TM) Graphics)

It uses the integrated graphics card but refuses to use the Nvidia Graphics card despite nvidia-smi detecting it.
How can I get it to use the Nvidia Graphics card?
