Can't use graphics in Matlab in openSUSE Linux 15.6

English Applications

Loading matlab -softwareopengl I get the following

com.jogamp.opengl.GLException

caused by

java.lang.NullPointerException

Should I go back to Linux 15.5?

Thanks a lot!

I have matlab (2017) and leap 15.6 I don’t see similar messages.

Are you getting this message upon starting matlab before loading a file?

If you are getting this after loading a file, post a copy of what you are loading. I’ll try loading it.

I write in matlab (Matlab2024b):

x=0:.2:1
y=x**2
plot(x,y)

and then I get yesterday message about not being able to perform the plot. The graphic windows opens, but nothing is plotted.

Thanks

In my old 2017a version I get a plot for the code you gave and no errors. The old version uses “exp” instead of “**”.

But running this code on matlab 2017a and leap 15.6 did generate a plot.
I haven’t used matlab in a long time. I use R, octave, and scilab but my old matlab does still work.

Since your error looks java related, maybe install additional java versions from yast software. I do have all java versions through v21 installed. I know virtually nothing about java. Maybe reinstall GL items.

I was wrong referencing exp but I did get a plot with no errors in matlab 2017a running in leap 15.6

Note:
x=0:.2:1
y=power(x,2)
plot(x,y)

This runs fine in matlab 2017a and generates a plot.

Thanks a lot. It seems that the same error happens in Ubuntu. I’ll continue working on the problem.

I have solved the problem: The command for matlab is now:

export MESA_LOADER_DRIVER_OVERRIDE=I965 ; matlab

from Willi Mutschler, with thanks.

actually: i965, NOT I965
