Created attachment 43945 [details] glxinfo/ldd glxinfo (direct rendering enabled) Over the weekend I built xorg-server 1.10.0 hoping to run Xdmx with GLX(proxy) successfully. Xdmx by itself runs perfectly fine, but as soon as I attempt to load glxinfo or glxgears I am greeted with a wonderful segment fault. I've tried running glxinfo/gears with both indirect and direct rendering enabled. I've also tried running it with the proprietary nVidia and Mesa GL libraries. No success. (Side note: I haven't been able to run Xdmx with GLX(proxy) support with xorg-server versions newer than 1.1.1.) The systems running Xdmx are identical in software and hardware. I've attached the the build log for Xorg-server with DMX support enabled. The backtrace from Xdmx with GLXproxy enabled (assuming I did it correctly). glxinfo direct/indirect rendering log with the latest proprietary nVidia drivers installed. I've also included the backtrace for the Xdmx version compiled with Ubuntu 10.10 (xorg-server 1.9 I believe...). Any thoughts? Sincerely, Jonathan

From a quick look, commit 7d74690536b64f7b8e8036507ab7790807349c50 removed the call to GlxWrapInitVisuals from mi/miinitext.c. glxProxy's InitVisuals function allocated __glXActiveScreens. That code was removed in commit a715de7f11afeda7798f0882148a94d4db2291e6 as unused. commit 7d74690536b64f7b8e8036507ab7790807349c50 Author: Kristian Høgsberg <krh@redhat.com> Date: Sun Oct 14 15:39:21 2007 -0400 Simplify and clean up GLX visual initialization. Instead of the fragile setup where we filter the modes common between the DDX generated GLX visuals and the DRI driver generated fbconfigs, we now just take the fbconfigs returned by the DRI driver to be our supported set. commit a715de7f11afeda7798f0882148a94d4db2291e6 Author: Jamey Sharp <jamey@minilop.net> Date: Tue May 25 13:10:05 2010 -0700 dmx: Delete unused GLX visual matching code. Kristian deleted this API from the rest of the server in 2007, in commit 7d74690536b64f7b8e8036507ab7790807349c50.

I am also affected by this bug on Ubuntu 11.04 and OpenSuSE 14. I will investigate reverting those commits and trying to build and test. If any developer needs more info logs etc, please let me know
Created attachment 62369 [details] [review] Patch v1 I was able to get glxproxy working with this patch, and by setting "export LIBGL_ALWAYS_INDIRECT=1" when running a gl app.
