Xorg.0.log

I have just updated to factory du jour and at the end of the zypper run, the X server suddenly restarted.

With rpm --scripts I checked if any of these had a whacky %restart_on_update, which turns out to be not the case.

Further investigation reveals:

# rpm -q --scripts xorg-x11-driver-input
postinstall scriptlet (using /bin/sh):
# re-plug the input devices
udevadm trigger --subsystem-match=input --action=change
exit 0
[...]

And Xorg.0.log.old shows:

[ 17472.459] (II) Unloading evdev
[ 17472.463] (II) config/udev: Adding input device PS/2+USB Mouse (/dev/input/ev
[ 17472.465] 
Backtrace:[...see attachment...]
Fatal server error:
[ 17472.504] Caught signal 11 (Segmentation fault). Server aborting

I have a plausible explanation for myself: the (old) X server process still running tried to dlopen and load a new, incompatible evdev.so.

Or could it be a dup of bug #720571?

Comment 1 Stefan Dirsch 2011-10-17 08:16:04 UTC

Thanks! Good catch! udevadm might also be the trigger for the Xserver crash in bnc #723777.

Comment 2 Egbert Eich 2011-10-18 19:10:48 UTC

Yup, that's a clear dup of bnc #723777.

Thanks for providing the right hint on how to trigger this! I was unable to reproduce this on my system but with your hint and many tries I eventually found it.
