Cannot enable hardware opengl R2021b Ubuntu 20.04

I have a fresh install of Ubuntu 20.04 and matlab 2021b. My machnine has a mobile RTX 3060 gpu and an 11th gen intel processor (system76 gazelle laptop). I have the latest nvidia 470 driver installed. I cannot enable hardware opengl, when I start matlab using a terminal I see this text:

MATLAB is selecting SOFTWARE OPENGL rendering.

running "opengl info" in matlab returns this:

I attempted to force hardware opengl by running "opengl("save","hardware")" and restarting matlab. After doing that and trying "opengl info" again I see this output

The "file" that the error message refers to contains this information:

I have also tried 2020b with basically the same results. I am pretty stuck at trying to figure out what to do to fix this. Software opengl is incredibly slow and spins up my processor a lot

[Mark Debord]

I have tried to install matlab-support package with apt, and that caused the MESA error messages at launch to go away, but after I launch matlab I still get this error:

I've tried the 'official' answer here (from 2012!!!) but no progress. I've also tried uninstall-reinstall nvidia driver, and even tried another completely fresh ubuntu install with an older matlab version (2019a) still with the same issues. I feel like I've tried all of the suggestions I've found elsewhere.

I have recieve official support from matlab with this fix:

Please create a file with the name 'java.opts' in the directory where you execute MATLAB. This file should have a single line:

-Djogl.disable.openglarbcontext=1

I generally launch matlab with a terminal from my home directory, so I placed the 'java.opts' file there and that has resolved this issue. I additionally had to set my preffered X renderer to Nvidia (by default MATLAB was using my onboard IRIS graphics for hardwre opengl). I was able to do this with the power settings icon in the system tray and selecting "Nvidia Graphics" instead of "hybrid". This will affect laptop battery life. Another option would be to change this setting in the nvidia x server settings application under "PRIME profiles"

To recap my setup:

• Ubuntu 20.04 with proprietary nvidia 470 driver installed an enabled
• MATLAB R2021b and matlab-support package installed
• created 'java.opts' file as discussed above
• enabled Nvidia graphics as system default (NOT hybrid mode, not iGPU mode, must be Nvidia graphics mode)

Thank you to Dennis Henneman from support.

[Ethan Blackwood]

Thanks, this finally solved my issue! I also found counterintuitively that I had to NOT launch MATLAB (through matlab-support) "using Discrete Graphics Card" in order for it to work.

[Pradeep Kumar]

Thank you...the fix suggested by Mark worked for me. Thank you so much Mark.

[Lea Anne Gainon]

It worked also for me! Thank you so much!

[Christopher Nix]

Hello

I am running matlab from the command line on ubuntu 20.04. I am also getting the message

matlab is selecting SOFTWARE OPENGL rendering.

The result is that the matlab environment gui has very tiny script and the graphics windows are so small to be useless. I am not sure if the fix suggested above will work for me, since I do not have an nvidia GPU. Instead I have MESA Intel Graphics (ADL GT2).

Could you let me know which matlab support package I should install and how I should enable the graphics as system default. I have created the java.opts file as mentioned above and this is sitting in my home directory, although the matlab executable is in /usr/local/MATLAB/R2021b/bin

Can you help please?

Thanks

Ivan Graham

[Lucija Babic]

Thank you, this worked for me too!
