Up to date hardware recommendations

Have you installed the matlab-support package? Without it, at least on my workstations with a Radeon Pro WX5100 GPUs and Ubuntu 20.04 + MATLAB 2020a, MATLAB’s hardware OpenGL always fails by default.

sudo apt-get install matlab-support

You point it to where your MATLAB is installed, and agree for it to replace the C++ libs[1], and then hardware OpenGL works fine, check using opengl info in MATLAB.

If you update MATLAB, you will need to reapply this, which requires a purge then reinstall:

sudo apt-get purge matlab-support
sudo apt-get install matlab-support

[1] I’m not sure if this is strictly necessary, this problem was supposed to be fixed, but I just always do it anyway…
