Attached is a log of a new Ubuntu 12.10 64-bit VM. Default settings, Easy Install.
After logging in, I resized by dragging the host window border. This happened around 4:34:45 p.m. and the screen froze for 30 seconds. Then the resolution changed. A few seconds later, in the guest a window popped up reporting a crash in XRandR, something about failing to get EDID.
(I thought I read somewhere that VMWare Player 5.0.1 is now compatible with Ubuntu 12.10. I did not expect so many problems.)
