When using the bug-report function, I encountered a bug again, prompting FileNotFoundError: [Errno 2] No such file or directory: ‘glxinfo’

Hello, I’m experiencing the same issue. The same file didn’t produce any errors with the 24.4.1 and 24.4 versions I downloaded previously. However, after installing 24.4.1 on a new Linux system today, the same error occurred.

Sorry for the difficulties here.
I will fix the bug_report script so that it does not fail if glxinfo is not present.
In the meanwhile there are several things we can do:

  1. Install glxinfo - if you are on Ubuntu it is part of the mesa-utils package. After installing that, try again to create and send the bug report.

  2. If that is not possible, modify $CONDA_PREFIX/lib/pythonX.Y/site-packages/mfixgui/bug_report.py to remove the call to glxinfo - simply remove these 2 lines at line 143:

        if sys.platform == 'linux':
            self.write_glxinfo()
  1. If that is not possible, just upload your .mfx file as well as any other files needed to run the case (UDFs, STL files, etc). Please also specify what version of MFiX you are using, and what type of system you are running on. The more information you can give us, the more it helps us to track this problem down.

Note that we are planning a bugfix 25.1.2 release as early as next week and we will try to fix these issues. Thanks for your patience.

Have you fixed this problem yet? I meet the same error.

I have fixed it, it seems a bug for GUI. When i build batch solver it works without problem.

This is fixed in MFiX 25.1.2. Thank you for your help in identifying and fixing this issue.
