Display occasionally stays blank after waking from sleep

[NoSmokingBandit]

Im trying to get my first EFI partition setup running and i cant seem to get a few things correct. The main problem is that when i wake from sleep my screen turns on (well, the led turns green at least) but stays black, then about 3 seconds later turns off. If i put my computer to sleep again via ctrl-alt-F12 it works perfect on wake. Theres no console messages explaining this, so idk what to do.

Its the machine in my sig, set up with EFI strings for gfx, patched appldeHDA in s/l/e, and the following kexts in my efi partition's extensions folder:

Appledecrypt

Appleusbechi

appleusbochi

appleusbuchi

ioachifamiliy

ioatafamily

jmicron

applertl8169ethernet

Bump

 

Im having this problem on my new build too.

 

Any ideas at all?

Try without all those USB kexts and use USBBusFix=y in Extra/com.apple.Boot.plist instead.

 

Or you can fix your USB devices in the DSDT (search).

I added the usbbusfix and the other usb fixes for chameleon to my boot.plist but the sleep still works only 50% of the time. It did fix the usb umounting error though, so it wasnt a complete fail

 

Would editing the dsdt have the same effect or do you think it would work better? If it does the exact same thing theres no point in trying it, but if you think it will make a major difference i'll jump in and learn how to do it.

 

 

Thanks!

You don't have to add the other USB fixes - USBBusFix=y means it applies both of the other fixes at once.

 

If USB works for you like this I wouldn't worry about fixing it in the DSDT.

If you are still curious though, download DSDTSE from here http://www.osx86.es/ - and start getting familiar with your DSDT. DSDTSE comes with most of the known fixes built-in, with code examples and everything. Compare for example the HPET fix to the HPET device in your own DSDT. At the ProjectOSX forums (also buried around here on IM) you can find dumped DSDT tables from real macs so that you can compare them to yours.

 

I think the other problem is with your video injection. What video card do you have and what injection method are you using?

 

The most recent injectors are NVEnabler (Nvidia - ProjectOSX forums) and ATY_init.kext (ATI/Nvidia - Netkas.org).

 

You could also try the built-in injector in Chameleon 2.0 (RC2 or higher).

I have a eVGA GTX 260 (core 216 model). At the moment i have ATY_init installed, but i've used NVEnabler before and got the same results. I have the injector installed and the drivers package from Netkas that doesnt have the model check. Using Chameleon's graphicsenabler flag doesnt work, my boot freezes after "oscpd starting" or shortly after. It does, however, make my boot screen 1680x1050, so thats kinda cool. Using both ATY_init and chameleon's enabler doesnt really change anything.

 

I'll check out the DSDT stuff and see whats up with that. DSDTSE looks pretty cool. I am not very comfy getting in and editing all that stuff by hand, so DSDTSE should help me out quite a bit.

 

Thanks for the help so far Beer, i appreciate it.
