Ubuntu is running as guest, the host is Windows 7. The attached information was fetched from the guest os and you can see the screen resolution changes in the XorgLog.txt. I am not sure if the lockscreen issue appeared at 404655.* or 407563.*. The following entries were caused by me trying to reproduce the problem.
