While the SEGV seems innocuous since it only happens with glxinfo, quite a few essential programs such as compiz use glxinfo to detect GL capabilities and this causes problems. This is fixed in Karmic which as of this time has mesa 7.4.1, but the issue still stands in jaunty's 7.4. [Symptoms] Segfaults in glxinfo. glxinfo reporting Xlib: extension "GLX" missing on display. [Patch] http://launchpadlibrarian.net/28340399/mesa_7.4-0ubuntu3.2.debdiff [Test Case] In an affected system (such as one with nvidia drivers loaded) 1. Run glxinfo 2. Errors with a segfault 3. Attempt to start compiz 4. Fails to start because it can't run glxinfo [Regression Potential] Essentially none. It simply adds a null pointer check right before dereferencing it. This fix has been tested in Karmic as well as upstream for some time, and was included in the 7.4.1 bugfix release. UPDATE:Oct 8 2008. installed daily updates ( 2.6.27-6-generic ) and still getting this same glxinfo error on boot ------------------------------------------------------------------------------------------------------------------------------------ I was running PlayOnLinux and tried to install 3d acceleration from there when glxinfo crashed.
