GNOME Bugzilla – Bug 789797
gnome-shell sometimes segfaults in init_output on HDMI hotplug events
Last modified: 2017-11-02 02:53:48 UTC
I have seen a bug across several GNOME versions where gnome-shell sometimes segfaults when a TV and AV receiver connected to the machine is turned off. This obviously triggers at least one, if not several HDMI hotplug events. It's not 100% reproducible but happens often enough to be annoying. The ABRT bug report from Fedora against version 3.24.3 is here: https://bugzilla.redhat.com/show_bug.cgi?id=1485786 with the stack trace being: #0 init_output at backends/native/meta-monitor-manager-kms.c:829 #1 init_outputs at backends/native/meta-monitor-manager-kms.c:1175 #2 meta_monitor_manager_kms_read_current at backends/native/meta-monitor-manager-kms.c:1213 #3 meta_monitor_manager_read_current_state at backends/meta-monitor-manager.c:1719 #4 handle_hotplug_event at backends/native/meta-monitor-manager-kms.c:1608 #5 on_uevent at backends/native/meta-monitor-manager-kms.c:1624 #10 monitor_event at gudev/gudevclient.c:104 #15 meta_run at core/main.c:648 This problem has happened since around version 3.22 starting in March 2017.
