Hello. I have a panasonic cf-y5 toughbook with the intel 945 chipset. Installed osx with the iPC 10.5.6 distro and everything seems to work with the exception of sleep or more accurately enabling the backlight after waking from sleep. As of know I have tried many different kexts, power management bundles dsdt patching utilities with no luck. I have searched various forums for a solution to my problem with no luck. My current configuration is the default iPC 10.5.6 base system, GMA950 video driver, intel ichx storage controller driver, ps2 keyboard fix, applebatterymanager with clamshellp display, smbios v6 macbook. I'm hoping to resolve this issue with your help and obtain a fully functioning hackintosh. I appreciate any advice, Thanks!

anyone out there know of a fix for this? the gma 950 seems to be a pretty common card from what I can gather from the discussion on insanelymac forums...

Same problem here. I have a Dell XPS M1210 with the GMA950 (945 chipset) and a acer aspire one, same graphics. I have tried lots of things, googled a lot and no solution found (yet). I used the program "InsomniaX" to avoid the sleep. I am finding a solution because if I close the laptop lid, the screen goes black and never came to light again... it is an annoying issue. Any one has a solution? Thanks.

I upgraded my hackintosh notebook to 10.6 and still unfortunately no backlight after waking from sleep. I'm hoping we can get someone with expertise in this area to shed some light on what's causing this and if theres any available solutions. Thanks.

not entirely sure what you mean by backlight. the display on the gma950 many times just goes to sleep right after boot. there are a few solutions to this.
read this for one. The gma950 works with stock kexts and sometimes EFI string is needed in c.a.boot.plist. example a few posts further up in same thread.

same problem with that fix as well unfortunately. Eveb for those with Leopard still what will happen is everything will wake up from sleep properly with the exception of the screen which has an image on it but the backlight is so dim that it isn't visible. It's not just a case of the screen being dim in this case and the sleep corners fix on that link you provided doesn't solve the problem unfortunately. As I said in my original post we need the find a way to enable/power up the backlight when waking up from a sleep image. Any one got any ideas on how this could be achieved?

hmm, it sounds familiar but can't recall back in my tiger days I had a problem like this. sorry, I am of no help with this. good luck!
btw. the only way my gma950 works is with EFI strings in com.apple.boot.plist. String obtained from OSX86Tools.

that's right, unfortunately even with the addition of the efi string from osx86 tools to boot.plist no luck. Oh well I might just have to live without it but it sure would be nice to be able to use the sleep function on my hacktop.

After digging through the extensions folder for something that might help my cause I noticed a kext by the name of applegraphicspowermanagement.kext. Is anyone familiar with this? What I hope we're able to do is edit something in the info.plist file to make it so that either A the backlight(brightness) is enabled on wake or B the backlight(brightness) is always 100%. Anyone have any idea how this could be done?

Today I tried reinstalling snow leopard with a different efi string obtained from the osx86 tools application and a usb kext that is labelled sleep friendly. The result, beautiful hardware accelerated Vanilla graphics and working sleep! From what I can tell everything works 100% on my toughbook now with the exception of the wireless which is currently being worked on by mercurysquad through project camphor.

with regard to my previous post: sleep worked the first time but for some reason hasn't worked again. Same issue of no backlight is present, using sleep mode "0". Back to the drawing board I guess

Would you mind posting EFI string and .kext?
