Dirk, > Since I upgraded the system has been somewhat unstable
Please clarify what you were upgrading from and when the instability began. The dpkg log attached to your bug report shows that you installed several compiz-related packages today (compiz-plugins, compiz- plugins-main, python-compizconfig, compizconfig-settings-manager), but these appear to have been new installs, not upgrades of packages; and there is nothing in your log file that suggests a recent upgrade of X-related packages. ** 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/1017045 Title: Xorg crashed with SIGABRT in raise() - 12.04 on amd64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1017045/+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
