I have been trying to solve this problem for the whole day without success. I have already reinstalled my virtual machine once and updated Fusion from version 6 to 7, but the issue reoccured on the latest virtual machine and Fusion version as well. It seems to be happening only after I updated the Ubuntu packages.
Host:
Macbook Air mid 2013, 8GB, iCore 7, 512GB SSD
OS X Yosemite
VMWare Fusion 7.1 (same problem on Fusion 6)
Guest:
Ubuntu 14.04 (64 bit)
Latest VMWare Tools installed
Issue:
On startup of Ubuntu, the BIOS screen shows up, then Ubuntu's splash screen shows up then the screen turns all black and the guest is unresponsive to any keyboard/mouse inputs.
Happened on a brand new installation of Ubuntu. The only changes I've done to Ubuntu were updating it's packages and installing some developer packages through apt-get, then customized the appearance of the desktop (in system properties, nothing in command line). It all worked well, until I rebooted the guest, when it all went to the blank black screen and I couldn't recover since then. Even holding down the SHIFT key to enter Grub doesn't work. I had to use the Live CD to update Grub's settings to force the display at startup, so now I can at least go to recovery mode. In recovery mode I tried reinstalling VMWare Tools, but it didn't solve the issue. I also failed to diagnose any graphics issues. Disabling 3D Acceleration in Fusion Settings didn't help.
