** Description changed: [Impact] gnome-shell will crash when resuming from suspend, if the monitor configuration was changed while machine was suspended [Test Case] -Suspend Laptop with external monitor connected -Disconnect external monitor -Resume from suspend [Regression Potential] Low, the applied patches discard the previous monitor configuration, but only if monitors changed while machine was suspended. === Original Bug Report === This happened on resume from S3 sleep. It seems related to multi- monitor support: I had an external display connected via VGA that I unplugged at around the same time as I suspended the laptop. The external display was unplugged when I woke the laptop up. There was a long pause with a blank screen before gnome-shell crashed and restarted (I've observed that pause in other gnome-shell crashes too; maybe it's just apport taking a long time to process the core dump? dunno). It then restarted, flashing the picture of my desktop before restoring the lock screen (this could have privacy/security implications). Bug 1190535 might be a duplicate; I can't tell. The stack trace in that bug seems mangled. FWIW the crash was a SIGABRT due to assertion failed: (n_outputs == config->n_outputs) which was visible in the function arguments passed to g_assertion_message() in the stack trace shown by apport before I submitted this bug. I don't trust the retracer bot not to mess up the stack trace like it usually does for PPA packages. - ProblemType: CrashDistroRelease: Ubuntu 14.04 + ProblemType: Crash + DistroRelease: Ubuntu 14.04 Package: gnome-shell 3.12.1-0ubuntu1~trusty1 [origin: LP-PPA-gnome3-team-gnome3-staging] ProcVersionSignature: Ubuntu 3.13.0-26.48-generic 3.13.11 Uname: Linux 3.13.0-26-generic x86_64 ApportVersion: 2.14.1-0ubuntu3 Architecture: amd64 CrashCounter: 1 CurrentDesktop: GNOME Date: Thu May 15 18:18:13 2014 DisplayManager: gdm EcryptfsInUse: Yes ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: b'org.gnome.desktop.interface' b'clock-show-seconds' b'true' b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" b'org.gnome.desktop.interface' b'clock-show-date' b'true' InstallationDate: Installed on 2012-07-25 (659 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) ProcCmdline: /usr/bin/gnome-shell - Signal: 6SourcePackage: gnome-shell + Signal: 6 + SourcePackage: gnome-shell Title: gnome-shell crashed with SIGABRT in g_assertion_message() UpgradeStatus: Upgraded to trusty on 2014-04-18 (27 days ago) UserGroups: adm cdrom dip libvirtd lpadmin plugdev sambashare shared sudo wireshark
