Re: [Scilab-users] Problem with plotting on Ubuntu 22.04 LTS

[Samuel Enibe]

Thanks Romain.
It worked perfectly.
I typed the command before starting SCILAB.

I suggest that SCILAB developers should find a way to incorporate this in
the next build of SCILAB.

Thank you very much.

God bless you.

Re: [Scilab-users] Problem with plotting on Ubuntu 22.04 LTS

[Pinede Romain]

Hello,
I had the same kind of problem but with different Scilab or Ubuntu versions ; 
have you tried to type this command before starting Scilab ?


export _JAVA_OPTIONS="-Djogl.disable.openglcore"

In principle it doesn´t sound reasonable to have to change the hardware when it 
worked fine in another version of the operatig system. Probably it is a driver 
problem. Perhaps the issue should be posted to the Ubuntu community besides 
this list.

I did and got exactly the the same and to solve the problem I tested different 
graphic cards and pilotes. So if you can change de graphics card or the 
pilote... The graphic aspects are really annoying...

In principle it doesn´t sound reasonable to have to change the hardware 
when it worked fine in another version of the operatig system. Probably 
it is a driver problem. Perhaps the issue should be posted to the Ubuntu

It was SCILAB graphics was working very well under Ubuntu 20.04 LTS. I
didn't change anything in the hardware.

Hi,

I got the same problem with Ubuntu 16.04, 18.04 and 22.04. It's not a 
Scilab problem but a graphics card, or pilote, problem. You should find 
the right graphics card with the right pilote. Not simple to solve if 
you cannot change the graphics card...
