I've had no issues with most updates, maintain my systems well, don't fool around with haxies, etc. My iBook G4 933 has developed a weird problem since updating to 10.3.5. Sometimes, maybe 20-30% of the time, when I wake the iBook up from sleep the color calibration is "off", it's much brighter with a blueish hue (Brushed metal looks blue-grey). I go into System Prefs ->Diplay -> Color and click on another color profile then back on the default one and all is well. My other two Macs (PM G4 and iMac 1Ghz) don't have this issue.
A minor annoyance really, but wondered if others have experienced the same issue.

Are you by chance unplugging a USB device after closing the iBook? I have this behavior if I put my Powerbook to sleep by closing it and then unplugging a USB mouse which will cause the Powerbook to briefly wake and then sleep again.

techtrucker · Aug 31, 2004, 06:50 PM

No, not unplugging anything, have a MacAlley USB Wireless mouse and a firewire external HD plugged in full time except when traveling...

I have the same problem, but not with sleep. My ColorSync profile gets switched whenever the screensaver turns on. I've had to stop using the screensaver since this bug was introduced. It's very annoying.

techtrucker · Sep 1, 2004, 09:48 AM

Wataru, with what version of the OS did this start happening? What it the 10.3.5 update?
BTW I filed a bug report on this with Apple.

wataru · Sep 1, 2004, 02:07 PM

No, I think it might have been 10.3.4. It definitely didn't start with 10.3.5 for me.

Thorzdad · Sep 1, 2004, 03:13 PM

Yup. Occasionally, OSX will forget what monitor profile to use. As you discovered, all you have to do is go into monitor prefs and click a profile.
Actually, you don't have to click a different profile. If your situation is like mine, when you open the prefs, the profile you set is still selected, but grayed. I just click on it and it comes back immediately.

Now really, wouldn't you get bored with your Mac if it didn't want to play once in awhile?

The problem is that it's not "occasionally," it's "100% of the time" when the screensaver turns on. I don't like to tinker with my system that much.

techtrucker · Sep 1, 2004, 06:36 PM

Thorzdad, you are right, all I have to do is select the profile, not select another first.
I don't mind once in a while, but it's definitely a bug that hopefully will be fixed.
Wataru, strongly suggest filing a bug report with Apple. I don't use a screen saver but for the heck of it going to use one just as an experiment...

techtrucker · Sep 1, 2004, 06:45 PM

Just experimented with screen savers. About 50% of the time when I stop the screen saver the color profile is off.

wataru · Sep 1, 2004, 06:59 PM

I griped on http://www.apple.com/feedback twice now.

techtrucker · Sep 1, 2004, 07:23 PM

Me too, once for awake from sleep and once for awake from screen saver. Hopefully 10.3.6 will take care of it...

azarel · Sep 1, 2004, 07:55 PM

I'm having the same problems too when I wake my powerbook up from sleep.

I think its since 10.3.5 that this problem has occured as I dun recall 10.3.4 having it.

techtrucker · Sep 1, 2004, 08:55 PM

Not to sound like a broken record, but please anyone having the same issue file a bug report with Apple ( http://www.apple.com/feedback/ ) , the more they hear about this the better our chance of seeing it fixed.

Photo678 · Sep 1, 2004, 09:58 PM

would love to except there is no link to the ibook

RayX · Sep 1, 2004, 10:46 PM

For those having the problem:

1. Which screen saver are you using?
2. Do you have 'Require password to wake this computer from sleep or screen saver' enabled?

File under OS X...

Seems to be any screen saver, I tried Flurry, Cosmos, and Abstract...

Didn't enable password required, will try that.

I have the same problem on an iBook G4 933ghz. Started with the 10.3.5 update. I'd classify it as extremely annoying�I dont' like glitchy behaviors. I'm filing the report.

10.3.7 now.. anyone still getting this problem? I get it 50% of the time now... =/ however my screensaver doens't mess up the color anymore. It is just sleep.

wataru · Dec 22, 2004, 09:38 PM

I still get it 100% of the time, and even after I did a fresh install of OS X.

cold aspiration · Dec 23, 2004, 04:15 AM

ok now if the display goes to sleep the color profile changes..

wataru · Feb 25, 2005, 10:55 AM

I found that this bug was fixed for me with 10.3.8. Huzzah!

I had the exact came problem on my 10.3.7 ibook. I just shut off the screen saver and the problem is fixed. I posted into the iBook forum about this, but received no answers.

wataru · Feb 25, 2005, 02:18 PM

Yeah, that's fine if you don't care about the decreased security from not having it prompt you for a password. But I do care about that.

As I said, though, the problem seems to be gone in 10.3.8.

Not for me... PB12 with 10.3.8... no hacks... still have the same problem... had it with both my PB12's since early in 10.3's at least.

Whenever I disconnect my external monitor, go to sleep, then wake up and reconnect the external monitor, it switches to an auto-generated color profile for that monitor, though it still shows my calibrated one as selected. To fix, I need to go into Display preferences and click the already-gray profile so that it actually uses it. Very VERY annoying.

As a work-around, I tried to delete all profiles for that monitor except the one I wanted it to use. (Went into /Library/ColorSync/Profiles/Displays and deleted the one for that monitor.) When I reconnected the external monitor, it recreated the file and used it instead of the one I want it to use (which is in ~/Library/ColorSync/Profiles). Ugh.

I really wish they'd fix that.

Devin Lane · Mar 29, 2005, 08:38 PM

This problem has happened to me, consistently, 100% of the time on two different machines ever since 10.2. Sleeping the machine, then waking it again results in a change of color profiles, even the correct one remains selected. I'm really surprised they've never fixed this.

dfiler · Mar 29, 2005, 10:22 PM

Ditto.

wataru · Mar 29, 2005, 10:46 PM

Yeah I forgot to post it here, but it turns out that the problem isn't fixed for me either. Now it only happens occasionally, but still often enough that I can't use the screensaver.
