Terminal: How do I stop Automatic Graphics Switching setting automatically reverting

You nailed it.

It's the 6,2 MBP

I have read about this issue, and saw that the board replacement program expired before I got there.

Bad luck. Was hoping a software end-run might solve it.

If it's just a logic board, is it soldered in or slotted in? How can I identify it when speaking to Apple?

I'm searching it right now.

As you know this MBP is getting on. But I like it. Actually love is a more accurate descriptor.

Getting frustrating though. I have a 2008 Mac Pro running SL server, love it too but have no upgrade path.

My wife's MBP, early 2011 upgraded all the way to mavericks. Go figure.

Can't seem to get the mountain lion software I bought to install on mine, now it's disappeared from the app store... and on it goes.

Unfortunately, the gfx.io won't work on 10.6.8.

looks like I'm hooped; caught in the Apple refusal to continue supporting legacy hardware, just buy more, throw the rest in the landfill, its a shame really, I think Jobs is weeping somewhere to see what this is becoming.

I appreciate your expertise!

No that doesn't solve it but thanks.

Something is reverting the setting on its own and this is leading to kernel panic.

I want to know where in the OS I can edit something to permanently disable the feature and be done with it.

With the mid-2010 MBP & 10.6.8, having the NVidia GT330M card, a bug causes a kernel panic and hard power cycle is required to restore

This is becoming a real pain and I can't find a fix for it.

I need to know where to permanently disable Automatic Graphics Switching beneath the GUI

thanks!

I watched some of the reflow vids out there, I'm afraid I had to scoff a bit though it sounds like some have had good luck with it. Seems pretty hit and miss, with as you note, high risk.

The app store, yes I checked hidden purchases, its just gone. The last download I got of it is corrupted and won't load.

Interesting that the problem emerged about six months or so ago. Was a dream machine until then. I use VPN and Fusion daily and that is where it began to show up. It's very annoying that I can set the switch in the GUI and set the lock to "prevent any changes" and then each time this occurs, on restart I look into the preferences and find that the lock is open and the setting is changed back to enable auto graphics switching.

I read widely last night regarding the i/o board replacement and it seems it has given very mixed results. For some the problem got worse and for others there was no change. While for a few it appears to have resolved the issues they were having.

I suppose I'll have to order a board and see how it goes. Cheaper than a new mac and I've no intention of ever buying a windows machine. I doubt after recent experiences that I will buy a new mac again either. Feeling a bit trapped.

thanks for your help!
