Created attachment 117888 [details] Complete xorg.log OpenGL Version is Downgrading from Opengl 2.1 to 3.3 in Ubuntu 15.04 When trying to Build Mesa from source code (Xserver version 1.17) The same behaviour is Observed with Ubuntu 14.04 and 12.04 (Xserver version 1.15) I am trying to Built Mesa from SOurce code (Mesa version is 10.5.2) Followed the Instructions from this link : http://www.x.org/wiki/radeonBuildHowTo/ Manually copied the dri from the Built Directory to /usr/lib/x86_64-linux-gnu Also Set the environmental variable But Still could observe that OpenGL Version is changing from 3.3 to 2.1 Please find the Opengl Version Before and After Building/Installing the Mesa from Source code : desktop:~$ glxinfo | grep -i opengl OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD MULLINS OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.2 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.5.2 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.5.2 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: :~$ glxinfo | grep -i opengl OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD MULLINS OpenGL version string: 2.1 Mesa 10.5.2 OpenGL shading language version string: 1.30 OpenGL extensions: OpenGL ES profile version string: OpenGL ES 2.0 Mesa 10.5.2 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16 OpenGL ES profile extensions: sudo ldconfig -p | grep libGL.so libGL.so.1 (libc6,x86-64) => /opt/xorg/lib/libGL.so.1 libGL.so (libc6,x86-64) => /opt/xorg/lib/libGL.so Also attaching the Xorg.log Please help to understand whta is going wrong in this Setup Thanks,
Please check if you have enabled floating point texture support.
If you don't want to go the manual build road there is the oibaf's PPA. Alternatively (apart from Grigori's suggestion) I would suggest grabbing your distribution source package and tweaking it to your liking. In some cases it's impossible to include all the distro specifics in a single generic wiki page :)
Yeah, indeed looks like an user error. Please follow the build instructions for your distribution. Resolving this as invalid.
(In reply to Grigori Goronzy from comment #1) > Please check if you have enabled floating point texture support. Thanks Goronzy , Enabling texture-float-point support helped to enable Opengl 3.3 in Mesa Thanks All for the Suggestions
