OpenGL Version wrong detected - XUbuntu 16.04.1 LTS [solved]

[ligginator]

Hi,

 

I have purchased the game via Steam and wanted to start it. Some libs were missing. Except for libGLEW.so.1.10, I could install all dependencies via apt-get. For libGLEW.so.1.10 I have created a symlink to libGLEW.so.1.13, which is the Version GLEW version installed at my Ubuntu.

 

When starting the game detects a wrong OpenGL-Version (see log). I use the nvidea driver from the repositories.

 

glxinfo | grep 'version':

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 3.3.0 NVIDIA 304.134
OpenGL core profile shading language version string: 3.30 NVIDIA via Cg compiler
OpenGL version string: 3.3.0 NVIDIA 304.134
OpenGL shading language version string: 3.30 NVIDIA via Cg compiler
OpenGL ES profile version string: OpenGL ES 2.0 NVIDIA 304.134 304.134
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.00

 

 

A small program linked against libGLEW.so.1.13

#include <GL/glew.h>
#include <GL/glut.h>
#include <cstdio>

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutCreateWindow("GLUT");

    glewInit();
    printf("OpenGL version supported by this platform (%s): \n", glGetString(GL_VERSION));
}

 

yields:

OpenGL version supported by this platform (3.3.0 NVIDIA 304.134): 

 

Thanks for your help in advance.

 

Cheers,

P.S.:

My system is:

NVIDIA GeForce 9400M

Intel® Core2 Duo CPU    P7550  @ 2.26GHz

8 GB RAM

 

P.P.S.:

I have replaced the libGLEW.so.1.10 by the file from this: http://packages.ubuntu.com/de/trusty/amd64/libglew1.10/download

But the output does not change.

So even with the libaray Version 1.10 the problem exists.

glGetString(GL_VERSION) is exactly what I'm using when querying for version numbers fails. Which happens in your case:

Sat Feb 11 13:08:44 2017| ContextInformation::ContextInformation():15: GLError in glGetIntegerv(GL_MAJOR_VERSION, &majorVersion): GL_INVALID_ENUM
Sat Feb 11 13:08:44 2017| ContextInformation::ContextInformation():16: GLError in glGetIntegerv(GL_MINOR_VERSION, &minorVersion): GL_INVALID_ENUM
Sat Feb 11 13:08:44 2017| Error detecting OpenGL version, trying to parse unknown version string

 

The result from retrieving the version string can be seen here:

Sat Feb 11 13:08:44 2017| Version: 2.1
Sat Feb 11 13:08:44 2017| VersionString: 2.1.2 NVIDIA 304.134

For some reason your driver/GPU reports version string "2.1.2 NVIDIA 304.134" to Avorion, from which Avorion parses the version number 2.1.

Hi,

 

using the nvidea-340 driver instead of the nvidea-304 driver has fixed the problem. But it is an interessting effect, that different programs get different OpenGL strings from the driver.
