Try adding GPU support to Kali servers

🚀 Feature Proposal

Try adding GPU support to our Kali machines and see if that improves guacamole performance.

Motivation

Some of the assessment folks are saying that guacamole can be laggy, particularly when watching multiple videos over it.

The Guacamole server re-encodes the VNC data as PNG and sends that to the client for display. For blazing-fast graphics performance, you would want to connect directly to the instance and remove guacamole from the equation.

If folks really need high-performance acceleration, then this link may be of use.

Even using guacamole, we should be able to get some performance gain by configuring X (and possibly VNC) to use the available graphics HW. I'm not sure why our attempts to do so have failed so far.
