> My setup: a Ubunt 14.04 server called 'roundvalley' has multiple Nvidia

> Client side is Windows. My goal is to use VNC to connect to the server and

> My question is, can I configure virtualGL to use any of Nvidia GPU even

> 6.2 Using VirtualGL with Multiple GPUs
> VirtualGL can redirect the OpenGL commands from a 3D application to any GPU
> in the server machine. In order for this to work, however, all of the GPUs

> First off I would recommend the following setup
Ubuntu Machine
Install VirtualGL, Turbojpeg, Synergy, Xpra
Windows, Machine
Installl Synergy, Xpra
This setup will allow you to run a full 3d desktop and just the 3d
applications you need. Example
Here are the two scripts I use. To start the server its just one command
#startserver
xpra start --max-size=1280x720 --start-child=start3dprogram
--speaker=disabled --bind-tcp=19
2.168.2.1:1000
#start3dprogram
vglclient -detach
vglrun -q 50 -c rgb /opt/bin/3dprogram
Then use Synergy to connect the keyboard.
Then you can just connect from the Windows client.
With this setup you have, clipboard,Audio,Print, 3d gl support and you save
resources from running just the 3d app. The configuration is also all gui
front end through xpra and synergy.
