Same problem here. 13" retina, mid 2014, VMWare 7, Yosemite 10.10, Ubuntu 14.10 (x86) with vmware-tools 9.9.0 (via vmware-tools-patches).
Specifically, it appears that when Ubuntu sleeps, I can't wake it up. The screen is black, but the pointer is visible. Mouse clicks and resizing do not refresh the screen.
