I don't recall, but I think both. It pretty much works now (both shutdown & restart), but occasionally fails. I am no longer using EvoReboot. I have been using Conti's patched ChamRC4 (see here: http://osx86.sojugarden.com/2010/03/...ack_v1-0-r111/) which includes the rekursor restart fixes. I'm not sure if it's the DSDT changes I made, or the Conti RC4, or both that (mostly) solves the issue for me.

I have reasonable values in IORegistryExplorer, but the slider doesn't work for me either. I believe it's because AppleIntegratedFrameBuffer is trying to directly adjust the brightness. I too don't care, since my function keys work (but not the ones with the Apple Sun icon).

If the Acer is using AMW0 for this, then you may need to disable that part.

I see you identified a lot of acronym/variable used in your DSDT. Nice. :)kizwan
Thanks. I only wish there were more standards for DSDT names.

Thank u uman for this link, it is really helpful for patching the Framebuffer kext; but when it comes to keeping the system totally vanilla, do u know how to load the patched kext (from /E/E maybe) without altering the original one ?

btw: sorry for the pic, corrected!

I will look in AMW0 section then. Thanks.

thanks for the link uman ; it was v informative, as was the asus link too. it didnt work though :( but maybe someone else over at insanely will be able to provide more insight into a hp dv3xxx hex conflict b/w apple...frambuffer.kext and the dsdt on 10.5

I am using 10.6, but the changes for apple...framebuffer were relevant and appropriate. it just didnt change anything, which leads me to believe that something needs to change in the dsdt, because the Fn + Fx works for other keys like media and sleep (which doesnt actually work either, but it tries)

Hi Kizwan,
I have a similar problem, although not exactly the same, on my Samsung N130 based hackintosh running SL X.6.3.

The brightness control works fine, either through the control panel or via the Fn key, but the system does not "remember" my settings, and set it all the way back to the maximum at each boot.

Not a big issue since I can easily lower the brightness as soon as I reach the desktop via the Fn key, but it's somewhat annoying on the long run.

I also tried to patch the AppleIntelIntegratedFramebuffer to bypass the hwBacklight function but just like you it didn't help (it's a pity because I was so sure this would fix the problem)...

It seems clear that the problem is with one of the last drivers to be loaded before showing the desktop, because during the boot, while the grey screen with the apple logo is shown, the brightness is OK, but just before showing the background picture I can clearly see the brightness being boosted to the max.

I really don't know where to look now, I saw some references to AppleBacklightAtBoot in the AppleBacklight.kext, not sure if this could be a clue.

Please please please, do let me know if you finally managed to fix this problem.

Thank you very much.

PS: Here are some interesting things from ioreg... Don't know how to work with that...

PNLF control method doesn't work for my Acer Aspire 9420. You might want to try display override. It may help Mac OS X to recognized your display better hence fix the backlight issue. I think I have read somewhere about this issue (backlight reset to max) but can't remember where. It is known issue but I don't know if there is a workaround for it.

Ok, thanks for your reply. I will open an other thread on my problem since it looks specific.

I'm am still not sure what your issue is. Is it:

1. When returning from sleep, your display doesn't wake up, or the screen is very dim? If so, there's a DSDT fix for that.

2. You can't control the brightness from the keyboard?

3. The keyboard does control the brightness, but the OS X "sun" icon doesn't display? (I have that problem-- when controlling sound from my keyboard, I see the speaker icon, but not when controlling brightness.

Re PS2: If you don't have a PS2K device in your DSDT, then you probably have a USB keyboard and mouse which is good! So I wouldn't add the PS2K device into your DSDT. (The sure way to tell whether you have PS2 keyboard or mouse is if during install, you needed VoodooPS2Controller.kext, or ApplePS2SomethingOrOther.kext.)

I find that the people who are doing the most advanced DSDT work are the Gigabyte mobo folks. Unfortunately there are pages upon pages of cruft to wade through on insanely, not to mention the ACPI Programmers guide, and the datasheets for your motherboard chipset. Even here, the Gigabyte topics are lengthy. But good on them-- they have the passion.

Try using google search to help cut down on the cruft:

site:www.insanelymac.com HP DV3510nr DSDT brightness

turned up some of your posts, but also: http://www.insanelymac.com/forum/ind...&#entry1095891

You could also try this: http://www.splasm.com/products/productbrightness.html

Hmm, your laptop has an nvidia display right? Can you check if AppleIntegratedFrameBuffer is loaded (use kextstat in terminal). Apparently that kext takes control of brightness (LCD backlight). There's a patch that gets it to relinquish control (see the comment by Timo: http://blog.stuart.shelton.me/archives/209)

Can you post your unmodified (original) DSDT? I'd need to see if your LCD panel has a _DSS method defined to control brightness. Macbooks (and my Gateway) don't. The _DSS method is where you see some people suggesting fixes where they use 0x86, 0x87, 0x89 to cycle, increase, decrease or zero brightness. But that doesn't work unless your hardware is defined that way. The ACPI spec has details on that.

I can't promise that I can examine your DSDT right away (and I made need a gentle nudge as I might forget), since I am installing SL over the next day or two. But I'll try to look into it later this wee or early next week. I'm curious how this wholething works because I'd like to get the litle sun icon to show up on my gateway!

Cheers.

Hi..my ASUS N61 . When returning from sleep, your display doesn't wake up.....

"1. When returning from sleep, your display doesn't wake up, or the screen is very dim? If so, there's a DSDT fix for that."

i can't find the DSDT fix for it!! can you help me ?? thank you !

.....I too have an Samsung N130 and was wondering if you can help.

I cannot change the brightness via the Fn keys. When I press Fn+UP arrow or Fn+DOWN arrow, nothing happens. I can change the brightness via the control panel immediately after a full reboot but it does not remember the state on the next restart or after sleep (I just get Max brightness like you).

But if I can get the Fn+UP and Fn+DOWN arrow keys to work then I can live with that. Any hint would be appreciated.
thx.
