Hi all,
Thought I would share a modest victory with you.
PROBLEM: On wake form sleep the display remained black, but every thing else woke up (i.e. disks spinning, system sounds from display speaker etc). Required a power down, cycle of the mains supply, wait 5 secs and reboot for display to come back on.
SOLUTION: I changed the following settings in UEFI (frankly don't have the time try and rule out the right combination but this works!):
- Init display first: PEG
- PEG Generation: 3 (not Auto)
- Enable Internal graphics: Yes (even though I don't use it)
- Internal graphics standby mode: No
- Internal graphics deep sleep: No
That's it, the system now sleeps/wakes perfectly.
I have the following kit:
Gigabit Z77N WIFI
I5-3570K
EVGA FTX 600 TI
Mountain Lion
No DSDT
Native Apple Nvidia drivers
Minimal Multibeast
PS - onboard bluetooth worked out of box no tweaking. No idea why it worked for me. Happy to share settings/diagnostics if you ask.
Good luck
