[Ubuntu-x-swat] [Bug 936893] Re: xorg segfaults with multiseat configuration
** Description changed: I am trying to enable a multiseat-configuration with Precise but Xorg segfaults, probably because of some of the input-device declarations. This configuration works with Ubuntu Oneiric so it is probably a regression.

[Ubuntu-x-swat] [Bug 936893] Re: xorg segfaults with multiseat configuration
Yes, it does seem to be a crash in the input subsystem. As to the core file, X isn't set to dump core by default; you'd have to flip that on. Since you're able to reproduce this crash fairly at-will, I would actually suggest instead of bothering with the core to just run X inside gdb, let it crash, and then grab a full backtrace. Don't forget to install symbol packages (i.e. the various -dbg packages). ** Package changed: xorg (Ubuntu) = xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/936893 Title: xorg segfaults with multiseat configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/936893/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
