** 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)
+ 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.
