Xorg.0.log from a clean boot attached.
Fired up the VM, went into full screen, logged in, grabbed the log.
BTW, the ungrab issue still exists. I did a reboot earlier today to see if a clean host boot + OS boot after a VM Tools re-install would possibly help. No luck.
I don't know much about what is in this log file. If you see something that is a clue please share the details. I'm a tech geek and could probably figure it out eventually, but it is always better to get the info from an expert on the subject.
