Bug#992991: matlab-support: R2021a Could not initialize shared resources for X11GraphicsDevice

Package: matlab-support
Version: 0.0.22
Severity: important

Dear Maintainer,

When running MATLAB R2021a on Bullseye, MATLAB appears to not recognize my graphics card.  This makes it impossible to plot graphs, unless matlab is run with the -softwareopengl option.  I get the following error message in MATLAB at startup:

com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x363a0dad, isOwner false, <53ad249f, 55216f24>[count 0, qsz 0, owner <NULL>]]]

I have managed to get MATLAB to run with hardware graphics acceleration by adding:

export MESA_LOADER_DRIVER_OVERRIDE=i965

to my profile.  This is from the following post on the Mathworks Forum:

https://www.mathworks.com/matlabcentral/answers/342906-could-not-initialize-shared-resources-for-x11graphicsdevice#answer_425485

My machine has an Intel graphics card.

Please consider adding support for Intel graphics drivers to this package.

Thank you,

Andrew
