Hi,
I can see many similar problems have been reported,but unfortunately I din't find the answer.
When I launch Matlab I get the following message:
MATLAB is selecting SOFTWARE OPENGL rendering.
MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
failed to load driver: iris
MESA-LOADER: failed to open kms_swrast: /usr/lib/dri/kms_swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
failed to load driver: kms_swrast
MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
failed to load swrast driver
Gtk-Message: Failed to load module "canberra-gtk-module"
I use Matlab R2021b, Ubuntu 20.04.3 LTS with graphics Mesa Intel® UHD Graphics (TGL GT1).
I can find e.g. iris_dri.so in /usr/lib/x86_64-linux-gnu/dri/iris_dri.so
and /snap/gnome-3-38-2004/87/usr/lib/x86_64-linux-gnu/dri/iris_dri.so
What should I change so that Matlab would find that path?
Thanks a lot in advance for your answers,
Kaisa

Same problem with MATLAB version 2022a. I was able to solve it on my system by doing two things:
  1. In directory ~/MATLAB/R2022a/sys/os/glnxa64, I unlinked libstdc++.so.6 and made a new soft link to the system version of libstdc++.so.6:
unlink libstdc++.so.6
ln -s /lib64/libstdc++.so.6
2. Following the advice of Mark Debord, I created the file java.opts in my home directory with the single line:
-Djogl.disable.openglarbcontext=1
Starting matlab from my home directory, opengl worked normally. Hope this helps others. Of course other distributions may keep libstdc++ in a different place so you may need to find that location.

Thanks a lot!
This solved all other error messages except the "Gtk-Message: 10:14:47.373: Failed to load module "canberra-gtk-module"

I have the same setup, and I got the same error now. Unfortunately I couldn't find a solution, but I can still use matlab with "matlab -nodesktop" command, since it is related to graphics driver or something. The strange thing is I didn't update any driver or any opengl related thing, this thing came like in all of a sudden.
