I have been trying to get my old nvidia Quadro2 Pro working in 4.0 cooking without success.
From http://www.nvidia.com/object/IO_32667.html
I need the legacy 71.86.xx driver so I downloaded that and compiled it. Now startx fails with:
dlopen: /usr/lib/X11/modules/drivers/nvidia_drv.so: undefined symbol: miTranslateRegion
Am I missing something or are these drivers not supported any more in 4.0? I know the card is quite old but it would seem a shame if that is the case.
