:Hi,
:
:X11 starts just fine, but after a while I always get a Fatal server
:error (caught signal 11).
:
:This happens with the intel driver. Xorg.0.log appended, together with
:xorg.conf and dmesg.
:
:Anything I can do about it? Any hints how to track down this bug?
:
:Regards,

Hmm.  If the server started fine and you weren't doing anything in
    particular (like switching to a different virtual console) when it
    failed, it could be an indication of a hardware problem.

A good test for memory / hardware problems is to run a big parallel
    buildworld and see if it fails in random places (usually with an
    internal compiler error or random seg-fault).

cd /usr/src/
    make -j 16 buildworld

Try switching off EXA and use XAA instead.

Thanks for your hints.

I don't know how to turn off EXA (I didn't even know what this acroym
stands for before looking at Wikipedia ;-). Nevertheless I fixed the
problem by switching to modular-xorg-server version 1.4.2 which is in
pkgsrc-wip.

Only one problem is still left. When switching to console and back again
to X11, I can't use the X11 applications any more. Only a xorg server
restart helps. But that's a lot less worse than random signal 11's :)

Regards,

Michael

I had some sort of same troubles on latest xorg update.
To check what is it:
uncomment Option "NoTrapSignals" from /usr/pkg/xorg/lib/X11/xorg.conf

and if it coredumps on libexa.so you can select XAA in your xorg.conf
in this way:

Section "Device"
[...]
Option "AccelMethod" "XAA"
EndSection

I've fixed in such way my problems.

Bye, \fer

Hi Michael,

I've observed that this happened with Xorg version 1.3 which is quite old. Does
it still happen with 1.6.3?
