X[7275]: segfault at 1b8 rip 53f8c3 rsp 7fffdc06a8b0 error 4 This is what I see in dmesg after X server crashes with both versions of nvidia-drivers. The message is always the same except for number after "rsp", which is quite random. Reproducible: Sometimes Steps to Reproduce: 1. Load X server with nvidia-drivers-169.09-r1 or nvidia-drivers-169.12 2. Start working (open windows, switch between console and X) Two very good examples: 1) After adding tracks to amarok playlist then click on a track by right mouse button and call tag editor. Segfault! 2) In kopete, just try to open a new window for chat. Segfault. I use ~AMD64 system, xorg-server version 1.4.0.90-r3, KDE version 3.5.9, Qt version 3.3.8-r4, GCC version 4.2.3, kernel 2.6.24-r3. I suspect GLX module, because no segfaults were catched after setting opengl to xorg-x11, and respectively no segfaults on xf86-video-nv driver. All drivers older than nvidia-drivers-169.09-r1 show no segfaults.
NVIDIA only provides their X11 drivers in a binary fashion, as such there is not much debugging or troubleshooting Gentoo can do with issues reported about them. You can use nvidia-bug-report.sh to generate some information to e-mail over to NVIDIA @ linux-bugs@nvidia.com and you may also wish to consider exploring NVIDIA's Linux driver forum @ http://www.nvnews.net/vbulletin/forumdisplay.php?s=&forumid=14 To further assist in debugging the issue and to have more information to provide NVIDIA (and have a better chance that your issue will get fixed in the future), you can attempt to debug your X server. To debug your server properly, please follow the documentation outline here, http://www.x.org/wiki/Development/Documentation/ServerDebugging The above link does not contain references to how to perform this properly on Gentoo. In a nutshell, you must rebuild X and it's libraries with USE=debug, add -ggdb to your CFLAGS, and add splitdebug to FEATURES. More information about this can be found at http://www.gentoo.org/proj/en/qa/backtraces.xml Since this bug is with nvidia-drivers, which is a package that Gentoo has minimal control over, this bug will be marked as UPSTREAM. However, in the event that you debug your X server and can produce a backtrace, please feel free to post it here and if it is unrelated to nvidia-drivers you or a Gentoo developer can re-open this bug and address the issue where it truly lies.
