opengl info HardwareSupportLevel: 'none', after reopening after crash

MATLAB encountered a graphics error, so I closed matlab and started it up again. Upon opening matlab I receive this message on the command line:

Warning: MATLAB previously crashed due to a low-level graphics error. To prevent another crash in this
session, MATLAB is using software OpenGL instead of using your graphics hardware. To save this setting for
future sessions, use the opengl('save', 'software') command. For more information, see Resolving Low-Level
Graphics Issues.

I then typed

opengl hardware

to switch to using hardware OpenGL. This returned this error:

Warning: Unable to select hardware OpenGL rendering. For more information, click here.

So I typed:

opengl info

and received this under the hardware section:

HardwareSupportLevel: 'none'

I have attempted closing and re-opening matlab several times now to no avail.

Anybody know how to get matlab to recognise the hardware and therefore switch back to hardware opengl?

I am using MATLAB 2017a on a windows machine running Windows 10, 64-bit processor: intel® Core™ i7-6700 CPU @ 3.40GHz, 16GB RAM

Seems to have a NVIDIA GeForce GTX 1050 Ti as the display adapter

Many thanks in advance.

Hi! Have you found a solution to this problem? Happening the same thing to me. Thanks!

Hi

I had the similar problem

but in my case, i used these commands

opengl info

d = opengl('data')

opengl software

opengl hardware

opengl hardwarebasic

opengl('save','software') #here you can either enter hardware, hardwarebasic, none instead of software

but MatLab suggested me to save the opengl as software

I did this and it worked

Running MATLAB on a Debian 10 Linux VirtualBox VM, running,

opengl('save','software')

is what fixed it for me (and made the fix persist to the next session).
