# cheap Quadro cards with dual-link DVI-D or DisplayPort work well. Quadro 380, 400, 420 and 600 have been reported to work on CCP4BB. Make sure the card can do dual-link DVI if your monitor has only DVI input. Any card (including the "Windows only" ones!) listed at http://www.nvidia.com/object/3d-vision-pro-requirements.html#Quadro should work if a) it can do dual-link DVI if the monitor has only DVI input, and b) if the monitor has built-in emitter. DisplayPort is fine with the BenQ XL2420TX.

The only way out is to install a different display manager, like documented at e.g. http://jensd.be/?p=125 . This works well - I'm now using lightdm and the MATE desktop, an NVidia Quadro K420 and a BenQ XL2420TX.
