Hi
I use Fusion daily with Apple OS X VMs and Ubuntu to do server development work. To fix the issue you are describing try this:
uninstalled vmware-tools with the command if they are installed:
sudo vmware-uninstall-tools.pl
I purged any instances of open-vm-tools like so:
sudo apt-get purge open-vm-tools*
Install the LTS version of the open-vm-tools:
sudo apt-get install open-vm-tools-lts-trusty-dkms open-vm-tools-lts-trusty-desktop open-vm-toolbox-lts-trusty
This should put you back to the initial setup when you first installed Ubuntu 14.04
