Comment 13 for bug 1717923

Created attachment 358188
monitors.xml

Ubuntu 17.10 Alpha

I built gnome-settings-daemon, mutter and gnome-shell 3.25.91 for upload to Ubuntu. I rebooted and tried to log in with my new packages (I had been using 3.25.90 before). GDM showed up but logging in to GNOME didn't work.

Workaround
==========
After moving or removing ~/.config/monitors.xml I was able to log in.

I'm attaching a copy of my monitors.xml file that mutter 3.25.91 couldn't handle but worked fine with 3.25.90.
