NetBookInstaller + Mac OS X 10.6.3 (Backlight Fixed)

I found a similar problem on the insanelymac forums (it's a pretty old thread and on 10.5.x, though). http://www.insanelymac.com/forum/index. ... pic=179326

It basically suggests importing some code into the .dsdt file. I haven't had time to familiarize myself with editing and compiling the .dsdt file so I haven't tried it yet. It might be an easy fix for meklort if it does work.

This is the same fix as noted by humph in :
http://s10lenovo.com/viewtopic.php?f=15&t=4024&start=0

I'm tempted to implement this although I am concerned about it being future proof regarding any new versions of Meklort NetbookInstaller (even after seeing the humph's update on the 1/4/2010 regarding kext compatibility). It seems many are suffering the same sleep + backlight problem going by the bug reports at the Installer google group and I would suspect Meklort is aware of it and working on a solution. At this stage it is hard to tell when that will be available. Probably with the next version on NetbookInstaller.

So.. I tried this fix as suggested by ronin510 and recommended by humph from the links above and it fixed the sleep and backlight problem associated with 10.6.3. and NetbookInstaller 0.8.4 RC1. The only caveat with this exercise is that one looses the ability to control screen brightness i.e. it remains static until the Function Flip fix is implemented. As far as I can see, this fix is rather extensive. I'm yet to implement the Function Flip section myself. Thanks guys!!

Just a quick how-to to re-iterate:

1. Download iASLMe http://www.mediafire.com/?jchmtymqlmd and use it to decompile your DSDT.aml to a DSDT.dsl (See instructions after opening the proggie but its as simple as drag and drop)

2. Edit your DSDT.dsl by adding this code:

Code: Select all

Device (PNLF)
        {
            Name (_HID, EisaId ("APP0002"))
            Name (_CID, "backlight")
            Name (_UID, 0x0A)
            Name (_STA, 0x0B)
        }


above the Device (PWRB) block of code.

3. Make a backup of the DSDT.aml just incase - sudo cp /Extra/DSDT.aml /Extra/DSDT.aml.bak. Recompile your DSDT.aml by dropping the edited DSDT.dsl file into iASLMe and copy the new DSDT.aml that is produced into /Extra overwriting the old one.

Reboot and voila!

            Name (_STA, 0x0B)
        }


above the Device (PWBR) block of code.

a li'l correction: everyone willing to try this, save yourselves a minute of confusion, it's PWRB, not PWBR.
otherwise, the fix works just fine, thanks a lot for this very useful tip!

I fixed the backlight problem. 10.6.3 updates the AppleIntelIntegratedFramebuffer.kext. I think the newer version takes precedence over the version we have in /Extra/S10Ext/ . To make our version work, follow these steps:

1. Go into /Extra/S10Ext
2. Open AppleIntelIntegratedFramebuffer.kext (right-click->"Show Package Contents")
3. Open Info.plist with TextEdit
4. Look for: <string>6.0.0</string>
5. Edit to: <string>1006.0.0</string>
6. Save.
7. Run UpdateExtra in /Extra and Restart.

We should now be able to sleep and have the backlight turn on again. I was able to figure this out by comparing differences between vanii's S10 Enabler and NetBookInstaller. Let's just say it's not a good idea to mix the two on the same installation...

Brilliant find, I'll confirm this on my install (when I reinstall again - why do all my projects involve me wiping partitions these days?) but I linked from my install guide as well. Good work!

i dont have a string thats 6.0.0

is it cfbundleversion or cfbundleinfodictionary?

or better yet, can you upload your appleintelintegratedframebuffer.kext?

i dont even have a /Extra/S10ext folder... only /Extra/GeneralExtensions
