Hi,
since about 1 month now I experience random crashes of the X server. The screen suddenly freezes, then I am again at the login prompt of KDE 4. Xorg.0.log.old says:
| Code: | Backtrace:

Fatal server error:
Caught signal 11. Server aborting |
I have no idea how to reproduce the crash. Sometimes the system is stable for more than a week, then it crashes 2 or 3 times in one hour. The only similar thing I could observe is that since the same time, emerge sometimes also gives segfaults (just when calculating the dependencies). The last update of the Xorg server did not help.
I am using the stable versions of Xorg and nvidia-drivers (that is xorg-server-1.6.5-r1 and nvidia-drivers-185.18.36). Kernel is 2.6.30-r5.
Anyone else with this problem or anyone knowing a solution? It would be great since I do not have the chance to save anything before the crash... |

I have no idea if it's related or not, but there were a couple of specific versions of the nvidia-drivers that caused some very strange behavior on my system. They would cause programs to randomly crash with a segfault. It was very strange because this included programs that have nothing to do with graphics, like what you mention with emerge. It turned out that this was either an issue with the driver's kernel module, or an interaction between that module and the version of kernel I was using.
As I understand it, this is possible because the kernel module runs as kernel code, so standard memory protection etc. does not apply to it. A flaw in kernel code can affect many other seemingly unrelated things. I believe that's what I experienced that time. I run a Hardened system and what I could not tell you is whether the same thing would have happened for a regular Gentoo installation, though I suspect it would.
In my case, I fixed it by updating my nVidia binary driver to a newer version that didn't have this issue. If possible, I'd recommend using the latest driver version that supports your hardware. If your hardware is fairly new, then that should be the latest driver available. Otherwise, you can look up which version to use on the nvidia.com Web site. |

| thank you causality for the comment. I have now the newest version available in portage installed, I hope it will help. |

I attempted multiple versions of the 190.42 nvidia drivers and downgrading HAL as well, and it does not solve the problem. |

did you try rebuilding x11-libs/libXfont ?
and remove all of those lines about fonts from xorg.conf

| Problem solved, it turns out I had two versions of the nvidia driver installed. I purged them and reinstalled the most recent one, and now it works. |
