opengl hardware refuses to work again after a crash

I have asked this question before but got no replies whatsoever. So am asking it again in the hope someone can help me.

When MATLAB encounters a graphics error, I close matlab and start 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 type

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 type:

opengl info

and receivethis under the hardware section:

HardwareSupportLevel: 'none'

I have attempted closing and re-opening matlab several times now to no avail. There appears to be absolutely no reason for this....

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.

answer_296755 It appears TMW thinks it's your problem, not theirs. :(

ah... :( any pointers as to what is going wrong my end then?

It seems that TMW presumes things about OpenGL hardware/firmwaare implementation that not every graphics hardware passes whatever checks it is that ML does for its definition of compatible.

The Answer indicates as far as TMW is concerned, your only option is to see if the vendor for your video chip has updated firmware for it that solves the issues or purchase a new video board failing that.

The only fallback that is left after introduction of R2014b is

opengl hardwarebasic

that might succeed but no guarantees.

Ok I will try seeing if there is any firmware available. Thanks for the tips!!!

[dpb]

I'd probably submit a service request anyway providing details of your system to see if there is anything else TMW might be able to offer; in the other Q? they did point the poster to what they at least thought was latest updates...

It works on Linux system

On a Linux system, you also can try upgrading the OpenGL driver or starting MATLAB with software OpenGL using this command:

matlab -softwareopengl
