            Bug ID: 103217
           Summary: Recent noveau causes errors with scilab 5.5.2 on
                    NVIDIA G84GL [Quadro FX 570]
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: sergio.callegari at gmail.com
        QA Contact: nouveau at lists.freedesktop.org

With git tip (as of today - 11 Sept 2017) launching scilab I get

javax.media.opengl.GLException: X11GLXDrawableFactory - Could not initialize

        ... 2 more

Almost sure, it used to work up to a few days ago.
Scilab works fine with LIBGL_ALWAYS_SOFTWARE=1

So ... what changed since a few days ago?

Find a version of mesa that works and bisect?

Contrary to what I have just said, scilab does not work anymore with LLVMPIPE
either, aka LIBGL_ALWAYS_SOFTWARE=1.

Almost impossible for me to bisect, since this machine is shared by multiple
users.  Currently, the machine is on git version of drivers only thanks to the
fact that there is a PPA for up to date drivers on ubuntu.  Unfortunately, PPAs
do not make easy to downgrade to previous versions of packages on the same PPA.

So it sounds like an issue not related to nouveau then?

--- Comment #4 from sergio.callegari at gmail.com ---
May be related, may be two independent issues. The way in which the issue
triggers is different:

- with nouveau, scilab complains at start up
- with llvmpipe, scilab does not complain at start up but throws java exception
as soon as you try to make a plot.

The two have in common some infrastructure code, I guess, so the issue may lay
there. Having both nouveau and the software rendering broken for this usage
case at the same time is a bit unfortunate.

Is scilab an application that I can run myself? If not, you're probably on
your
own.

Yes, it is. It is free software. You can download it at www.scilab.org. Please,
take version 5.5.2 (http://www.scilab.org/en/download/previous) since the
latest version (6) is young and has some problems on its own.

Once you have downloaded it, just unpack it in some dir. Then,

1) try simply starting. There is a bin dir, with the scilab executable in in.
With nouveau on my hardware I already get issues at this point.

2) If it starts, you get an application window which may include multiple
panels ( I do not remember if on a fresh install you have multiple panels or
just one). One of the panels is the Scilab Console. In it write
plot([0 0], [1 1])
and see what happens.
Most likely, you will get an empty plot and a java exception.

Nvidia is one of the biggest companies which make VGA cards for computer
gaming. The VGA card of Nvidia is better than any company because they have
higher world-class programmers and engineers. One of my friends told me that
wild jack casino is nice to visit and he sent me this
https://icasinoreviews.info/wild-jack-casino/ link to visit it. I am glad that
I do have a computer which has an Nvidia card in it.

After years of not sleeping well and not finding the right guide for natural
products online, she decided to do the research so others don’t suffer when
buying a new mattress as she did. For the past 3 years, she studied everything
about sleep and natural product to put the best natural mattress buying guide
online.
