    I just has the same problem happen to me today.  I have both an ATI 5870 and a NVIDIA Quadro card in my system.  I didn't get any random logout until I did the last CUDA 5.0 update.  Not sure it that has anything to do with.  It didn't happen until then.  This is not cool.  I have projects I'm working on and to have my mac logout during the work day is not cool.  I also didn't experience this problem when I was running Lion, only after Mountain Lion I've had the random logout's.

    Any word if Apple has even recognized the issue yet?

    I am experiencing this as well, Mac Pro 2009, 10.8.1, Radeon 6870 + nVidia GT120.  It seems I need to switch spaces away and then back to "home", and then at some point later on I will get logged out at a random time.  I'm hoping just not using Spaces will cure this for me until Apple can fix it, since I need the multiple cards for the number of monitors I have.  Will report a bug once I get home to the machine with its configuration info.

    Similar problem here. After installing mountain lion, it ran fine for about 2 weeks, then while working out of nowhere my screen went a little brighter, than to the grey booting screen, and then back to Mac OSX. All the apps closed and reopened slowly. At first I had no idea what was happening but since I only have one user I guess this is a logout but with immediate login afterwards.


    This happend roughly 20 times in 7 hours. In the crash logs, the crashing application alternated between WindowServer and Adobe-Software, depending what I was using at the time.


    Once I read this thread and disabled multiple desktops in mission control, didn't touch it since, the problme's gone for now.


    I installed the third party program TotalSpaces after installing Mountain Lion, after noticing out what functions where gone from Mission Control (I hate Mission Control with multiple monitors!), that where in the original spaces in 10.6. I disabled the app after expiencing the first few crashes, but that didn't fix the problem. However, since the app alters the Dock, it might be related.

    i just stopped using spaces / mission control and this fixed the problem completely

  • DamonBrandt Level 1 Level 1

    Stopping the use of spaces also means you can't use full screen apps btw. I stopped using spaces but if I put a app into full screen I usually get logged out pretty quick.


    I'm still patienty wait a bug fix.

    I was watching a movie and moved my mouse to my hot corner where I have mission control set and BAM! I was logged off.  WoW! It's hard to believe that Apple is not aware of the problem.  I can't tell any how great the now OS is because the OS is logging me off.  Maybe one of the last updates was a time limt to use the OS?

    Not using spaces does "fix" the problem.  As does only having one video card, but both of those are throwing out much of the advantage of working on a dektop.  Losing multiple monitors or the use of spaces is disastrous for me.  It completely inhibits my workflow. Fixing it by not using spaces is like a car with only first gear.  Yes it works.  You can still get places, but it sorta defeats the purpose of the machine.

  • calipvp Level 1 Level 1

    This is getting really old.    I did a check on updates and again I was logged off / crashed.  I wonder if Apply is aware of the problem?  I thought about going to the Apply store to see if they can give me any in-site of the the problem, but you know how that might turn out. 


    Please fix.

  • nicothegreek Level 1 Level 1

    hey guys, so I've been experiencing the same problem and found a solution by complete fluke!  Hope it works for some of you too..


    If you head to System Preferences>Security&Privacy then at the very bottom click on the Advanced button, you'll find an option that says "Log out after XX minutes of activity".  Make sure the option is unticked and voila!


    Well it helped me anyway, worth a try.

  • guywithabike Level 1 Level 1

    What people are reporting here (and what I'm experiencing) is a different problem. It's not a settings issue, it's an actual, low-level crash: dom-log-outs-in-mountain-lion/

  • Coolzy Level 1 Level 1

    That is exactly correct, guywithabike!  The problem that the OP (and several other of us) have is NOT solvable through any settings change.  Good find on that article!

  • longtime_apple_usr_unhappy Level 1 Level 1

    I'm having the same windowserver crashes while the box was unticked. So I don't think this is a solution for all of us. Anyway thanks for trying !! 


    This is definitely a mountain lion issue. When the F**K is apple gonna fix this issue. I'm getting logged out 5 times a day for over 2 months ....


    Apple support team !!! Are you there ????? FIX this !!! **** I'm gonna install ubuntu ....

    Exact same problem Frequent Logouts Terrible-  Reminds me of Old vista crashes and the reason I switched from Windows to mac in the first place.  Someone please find a fix to this very annoying problem.

  • parkermanor Level 1 Level 1

    Would you suggest upgrading video cards yet or just waiting for Apple to finally fix this issue.

    I don't have heavy graphic needs but enjoy multiple monitors and spaces

    Verry annoying

    Thanks for your post
