Matlab doesn't show up on Kubuntu 25.10

i tried installing MATLAB on Kubuntu 25.10, and did everything as mentioned in the guide / also like youtube videos. Everything went fine until i type matlab in the shell and try to open it after the installation. I only get the message: MATLAB is selecting SOFTWARE rendering.

Not even OpenGL mentioned, idk why tho. i have updated to all latest drivers and have a AMD GPU. i have seen some people who had similar problems, but with OpenGL in the command line. this is kinda weird, because i've tried everything in my knowledge so far. different matlab versions, reinstalled, ECHO Display, safe mode, updated everything, tried matlab-support package, tested OpenGL with gear ....

but it remains the same. matlab doesn't show up and the console is just like frozen after trying to start matlab.

if i change ECHO Display to 0.0 and type then matlab i get following output:

MATLAB is selecting SOFTWARE rendering

authorization required but no authorization protocol specified

i'm new to linux / ubuntu and want to use Matlab/Simulink. Kinda annoying that it doesn't work for whatever reason.

do you have any idea what i'm doing wrong?

From this page, it seems Kubuntu 25.10 is not supported for R2024b (no MATLAB versions currently do). Perhaps that could be the reason.

Still, it would be best to contact TMW support - Contact Support
