Mesa reports incorrect OpenGL version

edit

Oops, it turns out that I asked this question a bit too quickly! I finally found the answer myself. I will post it though, in case it might benefit others.

So I took a long time finding out what was going on (hence my post) because I was looking in the wrong place. Seeing that the nvidia module was loaded and that mesa was reporting an invalid OpenGL version, I believed that is was a mesa problem. It was actually a xorg.conf problem.

When I opened the /var/log/X/xorg.conf file, i found error lines complaining about the nvidia module being unable to load its glx module, and therefore reverting to software rendering. In this same file I found lines saying that a "Xorg foundation" glx module was loaded. It seems that nvidia uses its own glx module, not the Xorg fundation glx module. Using the information form this post ( http://forums.fedoraforum.org/showthr... ) i replaced the xorg.conf file with the contents from nvidia-xorg.conf, which ended up int the following file :

RPM Fusion - nvidia-xorg.conf
Section "Device"
    Identifier  "Videocard0"
    Driver      "nvidia"
EndSection

"glxinfo | grep -i version" now reports the correct version :

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.5.0 NVIDIA 375.39
OpenGL core profile shading language version string: 4.50 NVIDIA
OpenGL version string: 4.5.0 NVIDIA 375.39
OpenGL shading language version string: 4.50 NVIDIA
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 375.39
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
    GL_EXT_separate_shader_objects, GL_EXT_shader_implicit_conversions,
