I do not know if the above trace is related to X being locked or not. I'll also attach the /var/log/Xorg.0.log.old that had some information in it also andapparent segfault. That said, I think all log information is tens of seconds after the lock up and might be a result of me ctrl-alt-1 <-> ctrl-alt-f7 while system was in a borked state.
