Please advise how to properly install NVIDIA GT650m card. There was is no problem with other NVIDIA gt 240m (48 cuda cores only : pyrit benchmark 3300 PMKs per second) on my older laptop, but today I've bought expensive machine (Intel core i7, 8 gb ram, nvidia gt 650m 2 gb 384 cuda cores...) with this card for better pyrit performance. Nouveau was disabled, latests drivers was downloaded from, installed, boot/grub.cfg modifided as before, but after reboot : FATAL ERROR screen not found. I've tried to google this problem, not to many results yet, some forums said that it will not be supported for Linux... I don't want to believe on that. Can somebody tell me - will it ever work on Backtrack >??? thanks in advance.
