Re: [Scilab-users] Using Scilab on Linux Mint

[Federico Miyara]

This is from an old post.

For a while I couldn't find the time to play around with my Linux, but
this night I successfully installed Scilab 2024.0.0 on Linux Mint and it
works as a charm, graphs are plotted quite fast and more intelligently
than on Windows 10 (on W10 part of the figures are hidden by the bottom
of the screen, or the task bar).

So this is the happy ending of the story.

Thank all of you both for the replies and for making this work properly

Regards,

Federico Miyara

Right, it is a problem since since 6.1.

If one does not want to start Scilab in the terminal, I have written a
how-to at

#h3 for an elegant solution including integration into the menu

Re: [Scilab-users] Using Scilab on Linux Mint

[Stefan Du Rietz]

On a laptop computer of mine with Intel (8:th gen.) integrated graphics, the 
environment variable

_JAVA_OPTIONS="-Djogl.disable.openglcore"
makes some lines in a plot wrongly drawn, but

LIBGL_ALWAYS_SOFTWARE=1
makes them correct.

Re: [Scilab-users] Using Scilab on Linux Mint

[Stefan Du Rietz]

The strange thing is that at the moment, after

$ sudo apt update && sudo apt upgrade

the plotting works without setting a new environment variable! However, when I 
start Scilab from the command line, lots of Java errors are still reported.

Re: [Scilab-users] Using Scilab on Linux Mint

[Stefan Du Rietz]

Frederico,

First: How did you install Scilab in Linux Mint 21.2?
Version 6.1.1 with Software Manager or from the terminal (both from the 
repositories) or version 2023.1.0 from the Scilab download page?
I can then send a working desktop file to you.

Second: It is all about graphic drivers. I found this:
https://askubuntu.com/questions/1333764/scilab-graphic-window-appear-but-it-is-blank-there-is-no-plot-ubuntu-20-04-lts

Your questions:

1, 2) It can be either a global file in /usr/share/applications or a user-specific 
file in /home//.local/share/applications
Both will be visible in the Start menu.

3) Yes.

4) By searching the Internet (see above).

5) I hand over this one to the Scilab team or Samuel G!

Stefan

Stefan,

Thank you very much for your valuable help. However, it is embarrassing for me 
to confess that I'm quite new to Linux so I need a little more help:

1) Is the desktop file a system (global) file or an application file?
2) Where can I find it?
3) I assume once located I can edit it with any text editor, am I right?
4) Optional :)   How does one discover workarounds like this?
5) Is this a bug to be reported or it is a normal situation to have to tweak 
the desktop file? So far I haven't had this kind of problem with other programs 
using graphic capabilities.

Thank you again.

Regards.

Federico
