Public bug reported:
No matter how I try to lock my screen (Super + L, Menu Item, or Time
Out) the screen tries to lock, but freezes for a second, and resumes my
running gnome session as it was. If I try again after that, my session
freezes and has to be restarted.
If my computer is left at the regular login screen with no user signed
in, It will respect power settings, and turn the screen off after 10
minutes.
The following is a dump of my Syslog at the time of crash.
