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: 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>]]]

Warning: Unable to create com.mathworks.mde.liveeditor.LiveEditorClient, for details see

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.

Hi,

Ensure that you have followed the steps outlined on the following documentation page, especially the part about updating the graphics drivers and the statement: "On Linux® systems, use proprietary vendor drivers instead of open-source replacements.

Please refer the following: https://www.mathworks.com/help/releases/R2021a/matlab/creating_plots/resolving-low-level-graphics-issues.html

If this error ever appears for Software OpenGL, please try adding both of the following environment variables in a Linux terminal.

export MESA_LOADER_DRIVER_OVERRIDE=i915;
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0

The "MESA_LOADER_DRIVER_OVERRIDE" variable may vary from machine to machine (match to display driver which could be "i965" or "i915". These environment variables may help decrease the amount of error messages

I hope this helps!
