Annoying random logout in Lion!

[barky6]

What do I do with only one GPU? (I'm a poet and I knowit)

Yeah, it is a known problem with the Snow Leopard kernel and the Lion kernel. The code which switches between GPUs is buggy. My temporary solution was to the disable automatic graphics card switching in the Energy Saver preferences. This helps, but this activates the AMD GPU on my Early-2011 Quad-Core i7 17" MBP, even if i do not need it (90 percent of the time). So i looked for another solution, and found gfxCardStatus (based on a MacRumors project, IIRC). gfxCardStatus is just an application (no kernel extensions) which communicates with the kernel via userspace (vs. kernelspace) IOKit calls. I've activated the Intel HD 3000 IGP, and the sudden logouts do no longer happen.

Hope this helps you a bit.

Mr. Retrofire - my heart soared when I read your post - and I downloaded gfxCardstatus, but it obviously wouldn't work because my old MacBook pro has only one GPU. Any suggestions? Like others, this problem is causing me HUGE headaches and Apple is clearly on IGNORE. Thanks for any suggestions you can provide.

Finder crashes often with similar error on 10.7.3

it's been couple of weeks that Finder crashes very often on my 2007 MacMini.
Log says Kernel: The graphic driver detected corruption in command steam.
I reset PRAM as i had read about it on the Apple Discussion munites ago and crash hasn't happening yet.
However it's not a permanent solution. So anyone got updated news?

same here

i'm using Lion 10.7.4, and I had this problem before update, with snow leopard as well.

so can't imagine why, but it's the worst thing ever!!!

Same random logouts on this new Retina MBP since first setup.

Same thing happening on a new Retina MBP, model MacBookPro10,1, since August 1 or so.

It's running Lion 10.7.4, updated via Software Update. No hardware drivers have been installed on it yet, but VMWare and a Cisco VPN client were put on it before it was issued to me at the office. (I didn't set it up, but it's pretty standard setup and I would have done the same).

Random logouts happen now and then. I thought it was me bumping into the wrong key combo when I meant to do Cmd-Tab... but today, I'm sure. I definitely and carefully pressed Cmd-tab, while using Firefox (and with a few other apps open).

I'll pay attention to how long I was using it, and what's running, when it random-logouts on me. I'll try disabling the graphics-performance-switching feature, for now, hoping that this bug gets fixed by Apple eventually.

No, Mountain Lion's not an option for me yet, but if it's fixed in ML, that'll be good.

Spontaneous logout still happens to me, even though graphics switching has been disabled for a week. I haven't noticed anything special about what I'm doing, or running, that might cause this.

Thank you, that still happend in all the versions of apple up to date, installing this software fixed the problem.

I had detected how to reproduce this behavior (opening certain power point presentation, switching between master and normal view, had this problem), with this solution, I've no longer that problem.

Thank you again.
