After upgrading to xserver1.5, glxgears and glxinfo stop working. They output: Xlib: extension "GLX" missing on display ":0.0". glxinfo additionally segfaults. xserver outputs at load time: (EE) AIGLX error: dlopen of /usr/lib/dri/swrast_dri.so failed (/usr/lib/dri/swrast_dri.so: undefined symbol: _glapi_tls_Context) (EE) GLX: could not load software renderer Further notes: - xorg-server was compiled with -dri (using patch from Comment #10 from Bug 236851) - Load "glx" is in xorg.conf - xorg-server 1.3, 1.4.2 worked fine I suspect the sw glx extension was not emerged/installed right?

Could you try rebuilding mesa, then xorg-server? Thanks
> Could you try rebuilding mesa, then xorg-server? Have already tried, but no luck. I also tried adding the "none" option to VIDEO_CARDS for mesa, I thought it might be needed to enable software rendering. Also tried hacking the xserver ebuild to add "--enable-glx-tls" configure option, which appeared as a possible related cause after seaching on google. None of them worked.
Do you have the "nptl" use flag enabled? If not, try to enable it. Thanks
Phew, that was long ago. To be honest, I don't know anymore, since then my system is completely new (but still gentoo). I remember that one of mesa or xserver1.5 forced nptl to on or off, and I went along with that, whichever was forced by emerge. However, now I have xserver 1.5.2 and I do not have the problem anymore. Software opengl is working now.
Alright, thanks for the follow up. I'll close this bug fixed then. Please don't hesitate to reopen a new bug if you have any issues. Thanks
