            Bug ID: 105847
           Summary: Profile GL3bc is not available on X11GraphicsDevice
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: aidan.walton at gmail.com
        QA Contact: mesa-dev at lists.freedesktop.org

I'm running the latest mesa drivers for radeon using Obilaf's ppa: on Ubuntu
17.10.

glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 4.5
    Max compat profile version: 3.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.1.0-devel
OpenGL core profile shading language version string: 4.50
OpenGL version string: 3.1 Mesa 18.1.0-devel
OpenGL shading language version string: 1.40
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 18.1.0-devel
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10


I'm trying to run Scilab, which previously worked with an Nvidia graphics card.

Since I changed to Radeon, Scilab graphics are broken. Scilab have an old
issue:
https://wiki.scilab.org/Graphical%20issues%20with%20Scilab%205.X

Which relates to a lack of pbuffer support, but I think this is not related.
However the workaround they suggest does not help.

I have tested with glxgears that both software and hardware based OpenGL
function on my system by toggling the LIBGL_ALWAYS_SOFTWARE=1 env variable and
with Scilab it makes no difference.

I see from scilab debug logging that the java jogl call fails:

Caused by: com.jogamp.opengl.GLException: Profile GL3bc is not available on
X11GraphicsDevice[type .x11, connection :1, unitID 0, handle 0x7f6b4c766120,
owner true, ResourceToolkitLock[obj 0x21c3eea, isOwner true, <bbc9230,
355a3c78>[count 1, qsz 0, owner <AWT-EventQueue-1>]]], but:
[GLProfile[GLES1/GLES1.hw], GLProfile[GLES2/GLES3.hw],
GLProfile[GL2ES1/GLES1.hw], GLProfile[GL4ES3/GL4.hw], GLProfile[GL2ES2/GL4.hw],
GLProfile[GL4/GL4.hw], GLProfile[GLES3/GLES3.hw], GLProfile[GL4/GL4.hw],
GLProfile[GL3/GL4.hw], GLProfile[GL2GL3/GL4.hw]]

So even though the driver offers support for a version of OpenGL above this,
the profile required here does not seem to be available.

I have no knowledge of how these profiles are translated between the graphics
driver (Mesa) and what X11 offers to clients. But clearly there is a problem.

Any help appreciated, and apologies if this is an obvious problem elsewhere
that is simply my lack of understanding, but still as it does not work
