Stereoscopic view and the xserver's composite extension have been mutual exclusives, so that had to be disabled in xorg.conf and a non-compositing WM had to be used. That was subject to change in more recent drivers but I don't know to what extent. To have more information, please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post will reveal a paperclip icon.

Dear Generix Thank you for your response. Can you kindly elaborate a little bit, how to disable it in xorg.conf? Please find in the attachment, the bug report. Thank You Regards Zaved

Sorry, but you're lacking the hardware. You have two Teslas which are plain compute cards and your monitor is connected to the onboard rudimentary Matrox graphics, which (to my knowledge) is not capable of displaying stereoscopic images. Everything is software rendered on them, anyway. You would need an additional Quadro card for display.

Thank you for the response. Can't we utilize the existing Tesla cards to do the rendering job for any visualization software? Is there any way to do so? Thank You

Unfortunately not due to the Matrox being too rudimentary to do output redirection. It's a very simple device with a limited driver.
