This bug is a catch-all bug. If Xwayland crashes for any reason it will trigger gnome-shell death either in this bug or as bug 1556601.
While we appreciate everyone's efforts in diagnosing problems, in this particular case the issue is already understood and doesn't need much more comment. We can and will try to reduce the number of Xwayland crashes triggering this, which should be dealt as separate bugs. And separately, ideally, mutter/gnome-shell should not commit suicide when Xwayland crashes. The Gnome guys are already aware of this problem and say they would like to break this dependency in a future version of mutter/gnome-shell. That way even if Xwayland does crash it won't bring gnome-shell down with it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1505409 Title: gnome-shell crashed with SIGTRAP in x_io_error() from _XIOError() from _XEventsQueued() from XPending() from gdk_check_xpending() ["Connection to xwayland lost"] Status in GNOME Shell: Confirmed Status in Ubuntu GNOME: Confirmed Status in gdm3 package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Status in gdm3 source package in Artful: Confirmed Status in gnome-shell source package in Artful: Confirmed Status in mutter source package in Artful: Confirmed Bug description: https://errors.ubuntu.com/problem/d0252e2b465152efea2511e72f1e31681e2b2742 --- Occurred during start-up, before I did anything special... 1 Ubuntu Wily Werewolf (development branch) 15.10 2 3.16.3-1ubuntu6 3&4 not applicable ProblemType: Crash DistroRelease: Ubuntu 15.10 Package: gnome-shell 3.16.3-1ubuntu6 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Uname: Linux 4.2.0-16-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.19.1-0ubuntu2 Architecture: amd64 CurrentDesktop: GNOME Date: Mon Oct 12 19:22:07 2015 DisplayManager: gdm ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: InstallationDate: Installed on 2015-10-08 (4 days ago) InstallationMedia: Ubuntu-GNOME 15.10 "Wily Werewolf" - Alpha amd64 (20150924) ProcCmdline: gnome-shell --mode=gdm --wayland --display-server ProcEnviron: SHELL=/bin/false PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=nl_NL.UTF-8 Signal: 5 SourcePackage: gnome-shell StacktraceTop: ??
