I have an iMac G5 and sometimes after I start it, the screen is dimmed.

Would you say that the upper half is dimmer than the lower half? m.

That's a good question. I can't say that I've noticed that. If it is, its certainly not a great disparity.

Okay, then it doesn't sound like the same problem. There's a problem (fairly often discussed on the iMac G5 board at Apple) where the screen will partially dim suddenly. m.

I just got home and powered it on and the dimming even across the screen

It sounds like a different problem, as I say. Still, it shouldn't be happening. Plus you say that the Display pref panel fixes it - so what's going on? Are you saying that you start up the computer and the brightness setting itself has changed? m.

Exactly, the pref setting is all the way left. I think its a software issue, but I can't any references to my specific issue.

Right. This is clearly different than what they were discussing, where the screen goes dim unaccountably.

I can't think of anything to try other than the usual voodoo. Try zapping the PRAM. Try Panther Cache Cleaner. Try making a new clean user and be that user for a while and see if the problem is there as well. Sorry not to have a better recommendation. m.

These are the best recommendations I've gotten so far. I'll try them this weekend. Thanks
