How on earth have you guys managed to get sleep mode working on 10.4.9? it doesn't work for me and a lot of other guys I know.

Bizarre heh :thumbsup_anim:

I'm not really sure.
I played arraound with Paulicats Kernel and sleep worked with 10.4.8.
The I installed the JaS update and the sleep is also working with the new kernel.

Well I'm using the Mar 24 netkas SSE3 HPET kernel with dsmos.kext at the moment and Sleep mode will not activate.
NvidiaEFI also does not work for me with my GeForce 7800 Go, it used to be fine with 10.4.8 though.
Strange... perhaps there is something different with the JaS combo update, because I actually used the official Apple update and then replaced AppleSMBIOS/IONetworking/mach_kernel myself using Macdrive.

I heard the latest JaS 10.4.9 Combo update retains the 10.4.8 Nvidia kexts as default, can someone confirm this for me?

same to me - using jas 10.4.8 SSE intel only install with mifki kernel - sleep works right after first boot
after jas 10.4.9 update sleep works too.

only using applesmbios from paulicat.

but we need to figure out what happend on wake up so we can use both cores permanently.

I totally agree.

If this wake state is doing something to fix dual core then we desperately need to know what it is.

Yeah, thats really strange. What does a sleep change, so that both cores are working ???
Perhaps the Kernel Gurus can help ....

Well, for experimentation I replaced my 10.4.9 Nvidia kexts with the one from 10.4.8 and it 'almost' managed to sleep, but not quite.
It just hangs with a black screen when I close the laptop lid, which is the same thing Titan.kext does when I force sleep via the power button with the 10.4.9 Nvidia kexts.
I'm gathering JaS' 10.4.9 Combo update does not mess with the Nvidia kexts and leaves the 10.4.8 versions there, but clearly there is something else involved which is preventing me from fully sleeping.
Those of whom have JaS' 10.4.9 Combo installed, do you see Rotation enabled in the System Profile? is your GeForce.kext version 1.4.52.6 (8.7.5f3)?

Regards,

Pawel.

@devilhood
My Geforce.kext is 1.4.40. Date: 4.1.06
Do you mean with rotation the fast change of users in logon options ? (I have a german MacOS)
If so it is disabled.
@fruitylooper
uname -a in Console.

Ok, cool.

That confirms for me that the JaS 10.4.9 update uses only 10.4.8 Nvidia kexts.
When I said rotation, I meant the rotation of your display. This is a new feature of the 10.4.9 kexts, allowing you to change the rotation in display preferences.

I wonder what else it keeps.

Stephen: What exactly did you install? What DVD release, and how did you upgrade to 10.4.9? This information will help us find out how to get sleep working properly, and dual core =)

edit: forget me, my brain isn't fully working today.. I saw your post above heh.

Prasys told me that the dual-core stutter bug exists because of the 2nd core going to sleep.
Putting the laptop in sleep mode and waking it properly re-initializes the cores so they work simultaniously.
There could be a solution by using a good ole' soldering iron, but I very much doubt a software solution exists unless one is willing to crack the Dell BIOS.

To make this clear, this issue unfortunately cannot be solved in the kernel ;)

But this very unlogical. kernel initializes cores wrong on boot and corectly after wake up. so it's same kernel doing that =)
it's not a real bug but i think it can be solved by the kernel.

I agree. If others can reproduce the above (getting dual-core working after waking up), there must be ways to "simulate" such an event by means of software and without touching the BIOS.

I am also on an Inspiron E1505/6400 with 10.4.9 (latest netkas), but haven't yet managed to wake it up after activating standby.

After boot the cursor is in the upper left corner of the screen (just over the apple), so that it is no problem to activate sleepmode with the arrow keys (mouse is not working).
If you don't go to sleepmode, a black screen is appearing after about 30sec.

A automatic sleep after boot may be possible (perhaps there is something like /proc/acpi/sleep in linux)
A little startup skript may do the job (sorry I know only some linux, I'm not a Mac crack)
But you still will have to push the button for wakeup.
In linux a solution over RTC for auto wakeup is possible , but in MacOS ?

I hope we will find a more simple solution.

I think Titan is loaded twice at startup (only dual core boot), perhaps this is causing some problems too.

The kernel isn't actually doing anything wrong. It is purely BIOS related, with the way in which Power Management (S3) has been set.
Waking from sleep re-initializes both cores simultaniously, stopping this whole 2nd core going to sleep problem.
Dell are pretty strict with their settings and lock all functionality of their BIOS the moment a Service Tag number is entered in.

You cannot fix something like this with software, unless you can script a sleep/wake state during the boot procedure, though I'm unsure how viable that would be.
The best possible route is to try and reverse engineer the BIOS itself, because then we would also be open to the possibility of enabling AHCI too.
We'd essentially have a Macbook Pro clone if that was possible ;)
