I have the same crash as Rachel whenever I unplug the DVI from my NVidia graphics card or switch the KVM to another monitor. I use Ubuntu 17.10 latest, with mutter 3.26.2-0ubuntu0.1 installed. This does not fix the crash. I also get the assertion:

I was just retested the crash and it goes worse, now it is complete GUI crash not a "just session kick-out". I have created new bug report 1724557 due the fact that this bug 1717170 has fix released status and also because the behaviour and logs changed. -- You received this bug notification

Well, only what I have is again part of syslog (attached). If you can advice me how to provide better logs, it would be appreciated. However, it seems that the crash now is not caused by monitor switch off but by switching it on again, according to syslog. Nothing is logged between switch off and

I had one crash after applying this yesterday (and rebooting): it crashed right out to the console, not even to the login screen, and when I tried logging in again the session failed to start. But since a second reboot it's apparently been fine. This bug went away, and so too has my bug #1720149
