OpenGL Rendering in Matlab R2024b on Ubuntu LTS 24.04 fails: com.jogamp​.opengl.GL​Exception: X11GLXDrawableFactory - Could not initialize shared resources for ...

This error message means that 3D accelerated OpenGL rendering does not work. On same hardware R2024a didn't even try OpenGL, so this is a new problem. This applies to R2024b running on Ubuntu LTS 24.04 on at least two different hardware. There are many more reports here of same errors on older Linux distrubitions with older Matlab versions and probably older hardware, with same workarounds. But it would be better if 3D acceleration worked out of the box with R2024b or at least get disabled by default, if there is a problem.
The whole error message is:
com.jogamp.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for X11GraphicsDevice[type .x11, connection :1, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0x134ee3b8, isOwner false, <590c7f9b, 33bfcb35>[count 0, qsz 0, owner <NULL>]]]

This happens at least on the following Intel GPUs:
  • Intel Corporation WhiskeyLake-U GT2 [UHD Graphics 620]
  • Intel Corporation Raptor Lake-P [Iris Xe Graphics] (rev 04)
A workaround is to disable 3D acceleration with 'matlab -softwareopengl'.
On a laptop which has both Nvidia and Intel GPU Matlab automatically disables 3D acceleration when you attempt to use the Nvidia GPU:
jjaakkol@lx4-fuxi0:~$ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia matlab
MATLAB is selecting SOFTWARE rendering.
However if you force 3D rendering on the nvidia GPU, it seems to work fine:
jjaakkol@lx4-fuxi0:~$ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia matlab -nosoftwareopengl -nodesktop

其实大体思路就是首先确保openGL能够检测到你的独立显卡,然后再在matlab中启用硬件加速

Setting up an environment variable solved the issue and improved the graphics renderer (although softwareopengl fixes the error but produces poor graphics rendering)
In a terminal:
export DRI_PRIME=0
So run matlab in a terminal like:
export DRI_PRIME=0 && ./matlab -desktop &
I have two GPUs: DRI_PRIME=0 implements my iGPU, which is intel's integrated gpu, and DRI_PRIME=1 implements my NVIDIA GPU.
try both value and test it with this command in MATLAB Command Window:
rendererinfo
this is my output:
rendererinfo

GraphicsRenderer: 'OpenGL Hardware'
Vendor: 'Intel'
Version: '4.6 (Compatibility Profile) Mesa 24.2.4-1~24.04-tux1'

Hello,
I see that you are trying to resolve a 3D accelerated OpenGL rendering issue with MATLAB R2024b on Ubuntu LTS 24.04, which didn't occur in MATLAB R2024a.
You can follow the below steps to resolve this issue:
1) Executing the following command in a Linux Shell to start MATLAB. This command instructs MATLAB to only use software OpenGL libraries.
$ matlab -softwareopengl
2) Create a file with the name 'java.opts' in the directory where MATLAB is executed, containing the line:
-Djogl.disable.openglarbcontext=1
Then start MATLAB and everything should work as expected.
Please refer to the below documentation for more information.
Start MATLAB program from Linux system prompt: https://www.mathworks.com/help/matlab/ref/matlablinux.html
I hope this helps.

This looks like a AI generated answer. The problem/bug is that 3D accerelation does not work and the flag -softwaregl just disables 3D acceleration, so that Matlab starts.

The 2nd step is a copy of this (Willi Mutschler's) answer, although a bit clearer IMO. When using the linked solution I missed the '-' at the beggining of the fix and it didn't work for me.
Is it possible to amend the old one to be a bit clearer and just link it?
