Help with sleep - gfx doesn`t wake.

Taisto · #1 10-15-2008, 12:05 PM

Guys can anyone help me with fixing my sleep function ? It seems that both xnu kernels are working in this matter, system sleeps and wakes properly, i know this because i hear it`s working ( adium for example ) but after waking from sleep my gfx shows image for 1-2 seconds and turns off. Im using Mobility Radeon X1600 in my laptop so i have limited possibilities, especially in bios setting. does anyone have any idea what to do to fix it ? I would be grateful.

The only thing I can suggest is if you are currently using an injector, try switching to an EFI string as you'll get more 'native' support.

I was going to suggest the exact same thing that Voyn1x wrote. I suspect the injector kext unloads during sleep and is not being invoked when it's called upon after resuming. An EFI boot string should rectify this for you.

hmm, you are probably right - still, i don`t know how to do this, can you help me with this one thing more ?

Use EFIStudio or OSx86Tools...

PCWIZ has a great site with links and some help code here:
http://pcwizcomputer.com/

if you need help with either of these after reading a bit about it here... just ask.

EDIT: in regard to the second link... the part that I wanted you to read was what to do with the hex string once you had it... it needs to be placed in the com.apple.Boot.plist file near the bottom using this format:

Code:

<key>device-properties</key>
<string>##your-hex-string</string>

Im doing something wrong, or it`s not working.

I was having similar issue to when I put mine to sleep. So I started using EFI string but now that I get the computer to come back up from sleep, the dock doesn't work after the computer wakes up again. I also find that they system somewhat becomes unresponsive. I am using the latest Voodoo kernel (Beta 2c). What could be causing this to happen?

I have no idea CycloBot, im using voodoo beta 2 aswell. Anyway - does anyone have EFI strings for Mobility Radeon X1600 by any chance ? Maybe im doing something wrong.

I used EFI Studio to generate the string for my card and it injected the string to the bootlist file for me as well. Fairly simply process.

@ Taisto: Thats the beauty/pain of EFI. You can do it all yourself via the Terminal. It varies for everyone as it depends on your hardware setup. Use the Utilities for what they allow you to do, but ultimately you'll need to get the string and put it where it needs to be to make it work.
