We are trying to setup a server with Multiple Tesla M2050 to run with OpenGL. The current setup is as follows : Ubuntu 12.04 with NVidia Drivers. We have setup the xorg.conf with separate devices identified by BUS ID. Now we have tied an X server each with display which in turn is tied to each device and our code is attached to each of these X servers. But somehow only one X session seems to work out alright. The other one produces garbled output and while watching it from nvidia-smi, we notice that when the garbled output is being produced the GPU’s are not at all used. Could someone verify that our setup seems reasonable. The other thing we noticed was that, it was only the first X server that was started is the one that has the issue. Any help is appreciated.
