Make sure that you have xserver >= 1.13 and the new glxinfo with support for core profile (git version or the new mesa-demos 8.1.0 [1]) installed. [1] ftp://freedesktop.org/pub/mesa/demos/8.1.0/mesa-demos-8.1.0.tar.bz2 Yeah, the "server glx extensions" don't list GLX_ARB_create_context, so there is no way to create the core profile even if the driver can do it. Also, if you want MSAA visuals, you must install the driver and restart the X server. Only then glxinfo will print the visuals. For drm, kernel, ddx, mesa and xdemos, I'm already running the latest git versions. I'll have a look at the xserver I'm running, I'm using the version provided by ArchLinux. I'm almost sure it is version 1.13.something... (https://www.archlinux.org/packages/?sort=&q=xorg-server&maintainer=&flagged=) Here is the result from Xorg -version: This is a pre-release version of the X server from The X.Org Foundation. It is not supported in any way. Bugs may be filed in the bugzilla at http://bugs.freedesktop.org/. Select the "xorg" product for bugs you find in this release. Before reporting bugs in pre-release versions please check the latest version in the X.Org Foundation git repository. See http://wiki.x.org/wiki/GitPage for git access instructions. X.Org X Server 1.13.2.901 (1.13.3 RC 1) Release Date: 2013-02-15 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.7.5-1-ARCH x86_64 Current Operating System: Linux Xander 3.8.0-VANILLA #11 SMP PREEMPT Mon Feb 18 19:46:06 EST 2013 x86_64 Kernel command line: BOOT_IMAGE=/vmlinuz-3.8.0-VANILLA root=UUID=04e7cc91-6341-4f09-96af-a9553b9909ee ro quiet Build Date: 18 February 2013 03:52:56PM Current version of pixman: 0.28.2 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version. Something else must be missing. Any other propositions? Made a big Arch update two days ago, reinstalled mesa, drm, ddx from git and now it works correctly. Closing this bug. I still don't know what was wrong but it is now fixed. |

Created attachment 75469 [details] glxinfo, no OpenGL Core 3.1 According to docs/GL3.txt, it should be possible to create an OpenGL Core 3.1. Latest glxinfo doesn't report it. GL_ARB_texture_buffer_object is not reported. GL_ARB_uniform_buffer_object is reported. If I understand correctly, without TBO extension, there is no GLSL 1.40 and thus no OpenGL Core 3.1.
