Using Qubes R3.1. Was working fine until I added VGA device under devices and now after I enter the password for encryption screen goes Black. Is there any way to remove that VGA Device from the command line at boot or what would be the best way to remove that setting from the Grub prompt.

Try to boot with a rescue system, mount your root fs, chroot it and use
qvm-pci command.

Donoban, Thank you. Still new to Qubes, Do you know off hand what qvm-pci commands I would use to remove the VGA device that was activated?

Are you still having problems with this?

you should do:

'qvm-pci --offline-mode -d <vm-name> <device>'

you can use first 'qvm-pci --offline-mode -l' and find the device you
want remove.
