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.

```bash
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:

```auto
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…
