[VirtualGL-Users] server have multi GPUs not connected to physical screen

I have seen that error before using realvnc, Its because it can not
negotiate from the client a compression method so it dumps the connection.
You need to switch from realvnc to turbovnc on the windows client machines
like DRC says. Just grab turbovnc client for the windows machines.
