setup of Matlab R2021a on Linux Mint with GPU acceleration

Hi,

I just installed Linux Mint 20.1 on my computer (ThinkPad P51 with Nvidia Quadro 2200m).

I have issues regarding Matlab and also regarding the detecting the GPU.

After I boot my computer, I open the terminal and launch Matlab using the command

matlab $

Then Matlab opens but this appears in the Terminal:

libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)

libGL error: failed to load driver: swrast
libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)

libGL error: MESA-LOADER: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
libGL error: failed to load driver: swrast

and in the command line window in Matlab, this message is displayed:

com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x12660792, isOwner false, <455ae5c1, 28f5776a>[count 0, qsz 0, owner <NULL>]]]

I found that I need to run the following in the Terminal in order for this message to disappear:

export MESA_LOADER_DRIVER_OVERRIDE=i965

Then I launch Matlab again and check if it is using the dedicated GPU of my computer:

>> gpuDevice
Error using gpuDevice (line 26)
Unable to find a supported GPU device. For more information on GPU support, see GPU Support by Release.

Is there anything I can do to solve this issue?

Also, if I reboot the computer, the initial error comes back and I need to

export MESA_LOADER_DRIVER_OVERRIDE=i965

again in order to make the first error message disappear.

Thank you for your help.
