When launching matlab I get the following error: MESA-LOADER: failed to open iris:

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 here!

[Adrien Prévost]

Hi, same problem here !

[bouchra turki]

Hi, the same problem!!!

[Bryan De La Cruz]

creo que se soluciono con esto:

-----------------------------------------------------------------------------------------------------------------

cd /mnt/sda1/programas/matlab/programa_instalado/bin/glnxa64/../../sys/os/glnxa64/

mv libstdc++.so.6 libstdc++.so.6.old

ln -s /usr/lib/libstdc++.so.6 libstdc++.so.6

-Djogl.disable.openglarbcontext=true

[Richard Tennis]

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.

[Giuseppe Colantuono]

Thanks, this just worked for me with R2021b on Ubuntu 21.10

[Andreu Angles Castillo]

Thank you very much, also worked for me with R2020b on Arch Linux. Do you know what caused the problem?

[Richard Tennis]

I think it is a mismatch between the libstdc++ shipped with matlab and the versions present in more current distributions. They are probably based on different versions of libc/glibc.

[Andrino Moro]

Thank you so much for sharing this.

[Richard Tennis]

You're welcome.

[Luis Rosety]

Thanks!

That (almost) worked for me as well.

Ubuntu 22.04 on very old iMac 21".

The MESA-LOADER messages are gone but new Java messages appear in the Matlab command window.

In which directory shoud be saved that java.opts file?

Thanks again

[Luis Rosety]

Finally my solution was another simple one, following the suggested in askubuntu.com

Open Matlab with the command:

matlab --softwareopengl

Then, at the command prompt inside Matlab run the command:

opengl('save','software')

[Jonas Stein]

this does not help with matlab 2022a here:

Warning: Unrecognized command line option: -softwareopengl. 

[Kaisa Lakkala]

Thanks a lot!

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

[Juan José Torres Quiñonez]

-Djogl.disable.openglarbcontext=1 doesn´t work (commando not found)

[Richard Tennis]

-Djogl.disable.openglarbcontext=1 is not a command. It must be the contents of a java.opts file which is in the directory where you start matlab.

[Seagull White]

It is successful,but why?

[Rodney Cagle]

Worked perfectly. Thanks.

[Onno]

Amazing! Confirms that this works with MATLAB R2023a / Simulink, on Ubuntu 22.04.

[Chase Tolputt]

Great, confirmed this works on R2023a on debian 12 Bookworm

[Shutian Ma]

thanks for all of your contributions

[Dominik Viebke]

The main answer worked for me! 22.04 Ubuntu. Thanks

[chao]

thanks! it works for me! Ubuntu 22.04, matlab R2023a :)

[Chen QianCan]

um... my os(ubuntu23.10) was crashed after executed

unlink libstdc++.so.6

when I restart ubuntu 23.10, there are too many kinds of errors show

localhost thermald 814 /usr/sbin/thermald: /lib64/libstdc++.so.6 version 'GLIBCXX_3.4.32' not found (required by /usr/sbin/thermald)

also apt was dead.

I use matlab 2023b. orz

[Richard Tennis]

Sounds like you did the unlink in the system directory. You should only do this in the xxx/MATLAB/Ryyyy/sys/os/glnxa64 directory.

To fix your system you must re-link libstdc++.so.6 in /lib64 (or where ever it is located on your system) to something like libstdc++.so.6.i.j where you find i and j by "ls -l libstdc++*" in the correct directory.

Hope this helps.

[Bartosz Jemiol]

Thank you so much! This worked for me!

[Richard Ottermanns]

This works perfectly on my Devuan (Debian 6.1.99-1 AMD64). Thanks so much for this great advice.

cd /usr/local/MATLAB/R2024a/sys/os/glnx64
sudo unlink libstdc++.so.6
sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6
vim ~/java.opts
-Djogl.disable.openglarbcontext=1

[Richard Tennis]

Glad it worked for you. To get around the restriction of opening MATLAB in my home folder, I created a small shell script in my $PATH:

currentDir=$PWD
cd $HOME
matlab -r "cd ${currentDir}"

I called it mlstart and set execute permission:

chmod u+x mlstart

and then I can start MATLAB from any directory and still have proper graphics.

Answer 2

[Serguei Miridonov]

I did not try this solution but I have found another at Stackoverflow for Intel CPU: add environment variable

export MESA_LOADER_DRIVER_OVERRIDE=i965

It works on Ubuntu 22.04.1

Answer 3

[Alp Eren Yilmaz]

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.
