Hi,
I am not sure this is the right place to send the question. I am
wondering if possible your ACPI module could turn off all the graphics
completely. Therefore I could benefit from this when a number of
machines are running as a cluster.
Regards,
Shaw

There's no generic ACPI mechanism for this. Some machines with dual GPUs
have ACPI methods for turning the discrete controller on and off, but in
general you'd be looking at doing this from the GPU driver.
