Leopard on iMac G4 800 MHZ - dies on wake up!, Weird Options

[Miukku Maukku]

Hi fellows,

I am new to this forum, but was reading it for a long time! so finally decided to become a registered useR))

I have installed 10.5 to my iMac G4 800. Installed via OSInstal.mpkg replacement method... it worked for me perfectly.

Now, I have gone to make some coffee and whet got back to my iMac it was asleep... I clicked the mouse and wow, the screen has got green lines on it and then it started filling it up with white, getting absolutely white by the end...

Nothing helps to get rid of this, so I used power button to restart and temporarily switched off the sleep mode... Dont know what to do...

Has any of iMac G4 800Mhz users got this unpleasant thing or mine is unique one))

Thank you for you anticipation guys, really appreciate any help.

Is any hardware reset botton / nvram reset botton inside the imac?

Rgds.

[Miukku Maukku]

hm, good idea, but I do not know where are those buttons insideof it)) but i will try to reset those, hope it helps...

By the way, the Leo works even faster than tiger on my iMac, and widgets are not dead-slow if I compare that to tiger...

Still, topic is open...

I have installed Leopard on an iMac G4, too. Everything works fine, but my iMac shows the same symptoms as your iMac on wakeup. Should you find a solution I'd be really happy to hear about it...

[Meowy]

I have the same issues.

[Miukku Maukku]

Well, good point is that I am not alone with this) hehe, not good but still.. I got some friends who work for Apple as engineers so I think that will be able to shed some light onto this))) still waiting... by the way, how to make hardware reset or nvram reset?

Hi fellow Miukku Maukku,
please, can you teach me (us) how to install "via OSInstal.mpkg replacement method..." in SL DVD in order to enjoy it in my
B&W G3?
Many thanks!

Hey man, i tried via SL DVD thingy... no use for me.. trashed 3 dvds in vane... just got the OSInstall.mpkg file from Demonoid and relaced it in Leo disk image...

But I do not know if its gonna work on G3s...( However, it's not going to bite you if installs.. so worth trying))

2 iMac fellows: tried to replace the nVidia drivers in Leopard onto the Tiger ones... totally dead Leopard after this small surgery)))) no use...

I am also having the same issue with my iMac G4 800 not waking up fully from sleep. Instead of powering the computer down, I recommend SSHing into the machine and typing "reboot." I am waiting for the utility "Sleep Display" to be ported to Leopard. Is will allow the screen to sleep while keeping the computer running. If I can get the screen and hard drive to sleep, then that would be a good solution for me until someone figures out how to get sleep working again.

[Miukku Maukku]

It looks like the trouble is not in video card and drivers... it is more related to the power management of the whole sleep process... I hope 10.5.1 will fix it...

I attempted to get Hibernation (aka Safe Sleep) working on my iMac G4 800. The theory being that if the system completely powers down, it would re-initalize all hardware on power up, thus working around the problem. The downside is it would have to dump all RAM to disk on safe sleep and reload it on wake up. Thus making the sleep process longer. After following the instructions , the computer created a sleep image file in /var/vm/. However, I got the following error when the computer attemped to hibernate:

Nov 3 22:13:38 Mac kernel[0]: hibernate image path: /var/vm/sleepimage
Nov 3 22:13:39 Mac kernel[0]: sizeof(IOHibernateImageHeader) == 512
Nov 3 22:13:39 Mac kernel[0]: Opened file /var/vm/sleepimage, size 1073741824, partition base 0x58000, maxio 20000
Nov 3 22:13:40 Mac kernel[0]: hibernate image major 14, minor 5, blocksize 512, pollers 1
Nov 3 22:13:59 Mac kernel[0]: error 0xe00002bc opening hibernation file
Nov 3 22:13:59 Mac kernel[0]: IOPolledFileOpen(e00002bc)
Nov 3 22:13:45 Mac kernel[0]: System Sleep

I think power management is pulling the rug from under the disk subsubsystem before it has time to write RAM to disk. Plenty of others have been successful hibernating G4 systems, so Leopard is throwing a wrench into the works. Also, I found these errors when I tried to sleep the iMac, wake it up, sleep it again:

Nov 3 22:47:43 Mac kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0x8 = Fifo: Watchdog Timeout Error
Nov 3 22:48:05 Mac kernel[0]: 00000006

Nov 3 22:48:05 Mac kernel[0]: AppleUSBHub::setPowerState(0x20a9e00, 4 -> 2) timed out after 10101 ms


So I am not quite sure if this is a driver or a power management issue. The Graphics and USB channels not responding sounds more like a driver issue. Also, I see similar screen distortion right before shutdown and reboots, so sleep isn't the only time it happens.

Yeeeaah, Joe, man, that is indeed great...so this puzzle is gradually comning to the solution however... let us wait until Apple gets on the stage iwth its first update...

Even if we know where the problem is hidden, I do not think that we have enough skills to mess up with the hard code of the system)))

I am currently trying to play with the power management extension from the Tiger... lets see if it is going to work properly under Leo.

Any update on 10.5.1 fixing this?

[PPZ]

10.5.1 got out..... I am just downloading, so we will see....

[seremadedfs]

As for now... there's no change. In my Imac g4 800 the issue is still present.

Let's find a solution for this... Don't let the thread die.

[Meowy]

Same problem on 10.5.1 for me.

[PPZ]

For me too upgraded, but no visible improvement...

Disk Utility is still working 2 hours...no sleep....no display off....

[Miukku Maukku]

Yeppp, upgraded a few mins ago... same symptoms...crappy update....

2 seremadedfs - Agree, lets try to figure out how to fix this monsterbug) This thread should stay alive for sure until the issue is gone.

[Miukku Maukku]

Tried to delete the com.Apple. PowerManagement.plist and now my iMac on shut down shows no graphic aretfacts. But still, the sleep problem persists. Hm, what to do what to do...
