Scilab does not show the graphs

[Nistelroy_prada]

installing scilab in endless and when executing a code it does not show the graphs. This did not happen to me with the previous version of endless

Something that would help us a lot to understand the problem would be this:

1. Open the application called ‘Terminal’
2. In this application run the command:

eos-diagnostics

3. The above command will create a file with the information of your system (example: eos-diagnostic-160614_111731_UTC + 0100.txt); Send us this file so we can analyze and see a possible solution

I reproduced this problem. The following error is shown when Scilab is run from a Terminal window:

Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: Caught GLException: Not a GL2 implementation on thread AWT-EventQueue-0

This appears to be a known issue in Scilab. This page on the Scilab wiki documents some workarounds. The workaround that worked in my testing is:

1. Install Flatseal using the App Center
2. Launch Flatseal
3. Search for “Scilab” using the search button at the top-left

4. Scroll to the Environment section, press the + to add a new environment variable, then enter LIBGL_ALWAYS_SOFTWARE=1

Now, the next time you start Scilab, plotting should work.

I forwarded your report to the volunteer developers responsible for the Scilab build available on Endless OS.

A quick update here: I fixed the issue in a better way in the Scilab build, along with updating to the 2023.0.0 build. The workaround is no longer needed.
