I'm running F13 on my ud5 with GTX 580. Have not upgraded to 10.8.3 yet. What boot loader are you using? If you're using Chameleon, make sure it's a newer version if you're using graphics enabler=yes. I inject via DSDT. I had a similar problem with the 580 going to black when I first installed it. My solution was to update graphics section of dsdt to include "NVDA,Parent". There is a good guide for dsdt injection and this video card here.
I use d00d's dsdt for native power management here.
Excellent - Ill take a look at this. In answer to your question I used the last option in Hackinstaller - the Chimera boot loader (as it states better support of the Nvidia 5xxx cards).
The weird thing is I can install with the 580 no probs but was going to black on boot up. I actually got round the '1st boot up after install' by dropping in an old radeon gfx, booting with -v GraphicsEnabler=No. Ran Hackinstaller going thru steps 3 to 5 inc the dsdt. Plist edited the boot with GraphicsEnabler=Yes. Shutdown. Swapped out the Radeon with the GTX 580 and rebooted on the drive. Everything's fine apart from when I shutdown the computer never actually switches off after killing the drives. I have to press down the power button for a few seconds.Which kext will fix this? (Ive installed the kexts EXACTLY as Digital Dreamer's Mountain Lion kext pack hack installer into /Extra - with the only kext going into S/L/E is AppleHDA.kext)
Thanks for the help.
Digital Dreamer's vanilla dsdt patch - what exactly does it patch? Also whats the benefits of Firmware F13?
