Title: gnome-shell crashed with SIGSEGV in meta_monitor_mode_get_resolution() Status in gnome-shell package in Ubuntu: In Progress Bug description: https://gitlab.gnome.org/GNOME/mutter/issues/130 https://errors.ubuntu.com/problem/84e05b052e88b79520a684d6113084e9be8bc339 --- This happened while I was away from the computer. By the timing it should have been well after the time it should have gone *into* displaysleep, and was also about 45min before I returned, so certainly wasn't the wake-up process either. What I observed when I did return: My 4K monitor didn't wake up (that's a known problem with this monitor, Dell P2715Q), the second monitor (Dell U2711) did wake up, showing the login screen. So although I've considered my Dell 4K problem a problem with waking up, I wonder if it might be actually a problem with it apparently going away completely after a longer displaysleep (it's usually fine if I just do a short sleep of a minute or two). Another possibility is the cat stepped on the keyboard and thus triggered an attempted display-wake. But that would actually be out of character (for the cat). Either way is a bug because the session should survive monitor shenanigans... :-) ProblemType: Crash DistroRelease: Ubuntu 17.10 Package: gnome-shell 3.26.1-0ubuntu3 ProcVersionSignature: Ubuntu 4.13.0-16.19-generic 4.13.4 Uname: Linux 4.13.0-16-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.7-0ubuntu3 Architecture: amd64 CurrentDesktop: GNOME-Greeter:GNOME Date: Sat Oct 14 15:39:50 2017 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: InstallationDate: Installed on 2017-07-30 (75 days ago) InstallationMedia: Ubuntu-GNOME 17.04 "Zesty Zapus" - Release amd64 (20170412) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/false SegvAnalysis: Segfault happened at: 0x7fae20ab44a0 <meta_monitor_mode_get_resolution>: mov 0x8(%rdi),%eax PC (0x7fae20ab44a0) ok source "0x8(%rdi)" (0x00000008) not located in a known VMA region (needed readable region)! destination "%eax" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-shell StacktraceTop: meta_monitor_mode_get_resolution () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_calculate_mode_scale () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_update_logical_state_derived () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_rebuild_derived () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 meta_monitor_manager_xrandr_handle_xevent () at /usr/lib/x86_64-linux-gnu/libmutter-1.so.0 Title: gnome-shell crashed with SIGSEGV in meta_monitor_mode_get_resolution() UpgradeStatus: Upgraded to artful on 2017-08-22 (53 days ago) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1723615/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
