Q: Mountain Lion keeps logging user out...

I have just installed Mountain Lion. In 30 minutes of using it, I have been logged out to the login screen roughly 12 times. All at completly random times. This is very vexing as this will make a completely unworkable environment.

 

Is anyone having the similar problem!? What could the issue be?

Mac Pro, Mac OS X (10.6.7)

    Did you have to physically remove the card from the machine for this to work? Or was unplugging the monitor from the card enough?

    I just unplugged the monitor from one card and plugged it into the same card my primary monitor was on.  I didn't remove the second video card.

    I'll try unplugging it when I get to work on Monday and see what that does. Thanks. I don't think I can plug the 2nd monitor into the 1 card... both monitors have display port connectors and I think that each video card only has one display port output per card.

    Yes it seems there are a few different issues people are confusing with the main one... but it seems nearly everyone with the same symptoms I originally posted are due to Mac Pros & Dual Graphics cards having an issue with Mt. Lion.

    I've reinstalled Mountain Lion a couple more times and would like to confirm what others have said regarding the Mac Pro and two graphics cards.

     

    Just to recap, I had two problems:

     

    1. Icons would disappear from the desktop when changing Spaces and no amount of repairing, deleting plist files etc would stop it happening.

     

    2. I'd be logged out / all applications would suddenly restart with no warning.

     

    To confirm, by connecting two monitors to ONE graphics card, BOTH problems have been resolved. FYI: I left the second graphics card in the machine in the hope that Apple will fix this issue at some future date?

    In Terminal type:

    sudo pmset -g

    and hit the enter key, give your account password, hit enter key.

    in the lines presented look for ttyskeepawake

    normally this value is 1 even when you have set "wake on network" in EnergySaver to unchecked.

    Set it to zero,

    sudo pmset -a ttyskeepawake 0

    my suggestion is for you to call apple and report this issue so it can be brought to the engineers. I actually mentioned that the cause of the issue is rooting from dual graphics and looking at the number of people experiencing it it looks like majority is mac pro 2008s

    I have actually spoken with an engineer at Apple, they wanted to run Capture Data on my machine, but I am unable to devote such time to testing because I rely on my machine for work.

    Well, Apple Engineers - feel free to contact me, because I have a laptop i can work on while we resolve this issue. I'm getting fed up with having to re-open my files in Photoshop & Illustrator.

     

    I'm now running both of my monitors off the same Graphics card, we'll see if the problem continues or not.

     

    I think it's pretty clear it's a graphics card issue - it happens to me when I do something visually "intensive" even if it's not that taxing. Just certain calls to the graphics card and BOOM - back to login.

    I unplugged my second monitor from its video card, rebooted, and had no further issues today.

     

    Both of my Apple monitors have mini displayport connectors, so I can't try plugging the second monitor into a single video card... there is only one display port output per card. I guess I'll just have to live with one monitor until Apple can fix this issue.

    Same on this end.  I have a new MacBookPro (Retina).. no issues.  MacPro I purchased last year running on a single ATI 5870, no issues... office MacPro (early 2009) with dual graphics cards... crashes randomly.  Seems to crash when I'm changing spaces, or accessing the Dock after changing spaces.  Never a warning, simply greys out and returns me to the login window.  To this point, I've lost almost all work I've attempted today as it continues to crash and all data is lost as the apps reopen.

     

    I'm hoping Apple has their engineers working on this right away... this problem has completely rendered my office system useless unless I downgrade, or opt for a single monitor while it's resolved. 

     

    Has anyone here submitted a bug report, or contacted Apple support directly?

    Yes i have spoken with Apple directly about this issue, last i heard it was a mystery to them and they were looking to run tests to solve the problem. However, I, in the same position as you, had to downgrade in order to keep up my workflow.
