Tesla M2070 OpenGL Functionality

I am using an IBM iDataPlex dx360 M3 workstation.
Till few days ago, I don’t know how, my software engineer found a way to utilize the Tesla M2070 OpenGL functionality.
I am running Ubuntu 10.4 server. I had to delete my private directory, since the encryption overhead was too big.
Now I lost the OpenGL functionality of Tesla cards.

Any suggestion


I used the Xorg -configure, instead of the nvidia-xconfig.
