joe.s i was updating my Nvidia Quadro graphics driver to version 311.15 today and noted the release notes had a rather interesting section on Tesla C2075 'modes' which i a shall repeat here:
C2075 TCC mode
Prior to version 275.89 of the graphics driver, the C2075 companion processor booted into standard (WDDM) graphics mode on 64 bit windows 7 systems. Starting with version 275.89, on 64 bit windows 7 systems the C2075 boots by default into TCC mode, not WDDM graphics mode. In TCC mode the C2075 behaves strictly as a computing GPU and does not drive or render to a graphics display.
It is possible to toggle between TCC and WDDM modes using the Nvidia smi utility:
nvidia-smi -g (GPU ID) -dm (0 for WDDM, 1 for TCC)
Finally, in mixed Nvidia Quadro + Tesla C2075 configurations, if a display is connected to it, the Nvidia Quadro boots into standard graphics mode and drives the display while the Tesla C2075 defaults to TCC mode.
Tesla Systems: nView not installed
This is expected behavior. For windows 7 and windows vista, nView installs only on Nvidia Quadro and Nvidia NVS systems, not Tesla systems.
So, if you want to use the Tesla card for graphics output, you need to use Quadro driver version lower than 275.89, or if using the latest drivers you need to set the Tesla boot mode to WDDM using the Nvidia smi utility as indicated above.
Also note that you can not use the hardware mix you have chosen. A GeForce card using a Quadro driver will not work, and likewise, a Tesla card using a GeForce driver will not work. Use the Quadro driver with any Tesla card or mixed Tesla and Quadro card setup.
Hope this clarifies the situation.
