Matlab hangs when closing/exiting on Ubuntu 16.10

27 views (last 30 days)
I can start and use Matlab with no problem, except when trying to exit. When I hit the close button on the top right corner or type the exit command, Matlab hangs. I have to manually kill the process. No problems exiting when starting matlab without jvm.
Is there any fix or workaround to this problem?
I am currently using Xubuntu 16.10 and Matlab 2016b (student license).

This crash may be related to an issue with the graphics drivers. You may be able to resolve this problem by running the following command in MATLAB:
>> opengl save software
Restart MATLAB and see if the problem still persists.
If the problem still persists or you never get a MATLAB command prompt at all, check to make sure that your user account has access to a home directory.
If your account is using symbolic links to point to a home directory, remove them and grant access to an actual home directory and the issue should be resolved.

That worked like a charm. It seems like the issue was that my laptop's graphics wasn't cutting it.
Thank you!

Hello there!
I have the same problem on my Ubuntu 20.04
Running "opengl save software" did work for opening and closing MATLAB only, but the problem persists when Simulink is used.
I have tried Opening MATLAB, (1)running "opengl save software", (2) opening simulink, then (3)Closing simulink, and finally closing MATLAB. After this process, MATLAB still hangs in the background, even when doing (1) after (2) or after (3).
Is there any variant of this fix for simulink?
