Matlab getting crashed due to software rendering in RHEL8 linux

Hi All,

My MATLAB crashes with postscript files for redhawk on E2C linux. I observed that when I open MATLAB in my Linux RHEL8 machine for post processing, I get a warning that "MATLAB is selecting SOFTWARE OPENGL rendering".

Please suggest how to resolve this error, while working on Windows, there is no issue faced.

Regards

Balaji

Hi @Balaji Seelam,

I understand from your issue that you are getting the warning "MATLAB is selecting SOFTWARE OPENGL rendering" when MATLAB is opened on a Linux RHEL8 machine for post processing. The possible reasons for the error and their fixes are mentioned below.

• Check if the drivers are up-to-date on your machine. Outdated or incompatible graphics drivers can cause issues with software rendering.
• Ensure that your system supports the required version of OpenGL. This can be checked by running the following command in the terminal:

glxinfo | grep "OpenGL"%ghjj

• You can try opening MATLAB from the terminal with the following command and check if hardware rendering is selected.

matlab -nosoftwareopengl
