GTX 560 (non TI)
I made the ML install USB key with Unibeast, I had to add my GTX560 PCI ID (1201) into the ML USB NVDAGF100 kext, I am able to boot on the usb key without option, full video (2560x1440), install ML on my internal HD,
reboot on the HD without option, finish ML installation without problem, then when I reboot I can't go back to the graphic login, every time my monitor fall back in sleep.
I will have to look more into it, but I guess the ML installation reinstall a kext without my GTX560 ID in it.
some people here seems to have no problem with that card, some other are not able to use it.
I read that ML work with all GTX5xx card, how can it does that ? if the PCI ID is not in the kext file ?
(for Lion 10.7.4, I had to add the PCI ID in the kext too for all my graphics card (odd DELL GTX 260, ... GTX560 (non TI))
