Bug 266236 – x11-base/xorg-server-1.5.3-r5 segfaults after some time

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Markus 2009-04-15 11:13:33 UTC]

After some time X just exits and I am at the login-screen again.
The Xorg.log says:
Backtrace:

Fatal server error:
Caught signal 11.  Server aborting


Reproducible: Always

Steps to Reproduce:
1. Build new Xorg and use it

Actual Results:  
It segfaults.

Expected Results:  
It should just work :-/

I upgraded and used the same config (only the mouse-config was updated to no longer use the name but the path...)

What I figured out so far:
It happens randomly but it can only take a few minutes.
It happens when a window should open up. (It cant connect to the server as stated in the user xsession-errors and all other a killed because they lost the x-server.)

[Comment 2 Markus 2009-04-15 14:38:36 UTC]

"window should open up" is also the case for menues btw.
Without doing anything, it runs without a problem for hours. (no failure at all)

[Comment 4 Markus 2009-04-16 11:10:39 UTC]

The xorg-server should be masked untill this is resolved. It is definitly unusable!
It may be something like bug 238634.

[Comment 5 Jeroen Roovers (RETIRED) 2009-04-18 00:06:36 UTC]

Please attach a Xorg log file that explains what drivers are used. Also explain whether you did or did not rebuild x11-drivers/*. Then reopen this bug report. 

Also, it isn't critical or a blocker just because you happen to experience it.

[Comment 6 Miroslaw Mieszczak 2009-05-14 14:18:59 UTC]

It seems there is a problem with nvidia.
option "Backingstore" "false" is needed.

Please see bugs:

[Comment 7 Pouya K 2009-05-18 17:06:24 UTC]

I am also having similar crashes. I can't produce them very reproducibly (they occur sporadically). I have noticed that trying to open openoffice makes them much more likely to occur (although I can open openoffice several times without it occurring). 

Here is my backtrace:

11: /usr/bin/X [0x42f9a9]


Notes: I do have an nvidia card, but did not have backstore enabled. I think this started when I moved to 1.5, but at one point I also updated my kernel and disabled acpi (this is not a laptop). I am on AMD64. I am attaching a full log of a crash (I plug/unplug my keyboard and mouse frequently which is the cause of the many messages about them coming back online) and my Xorg.conf.

[Comment 10 Pouya K 2009-05-18 17:11:00 UTC]

Also, I have emerge all my x11-drivers (x11-drivers/xf86-input-evdev-2.1.3 and x11-drivers/nvidia-drivers-180.29) since my last emerge of xorg-server (x11-base/xorg-server-1.5.3-r5). It does appear that multiple people are experiencing this bug so maybe it should be considered critical/blocking... it certainly outweighs any benefits from this upgrade.
