Nov 19, 2015 7:50 PM in response to Paul Hodson3by pbronze,Everyone, This is due to a preference configuration change. After research I found the answer.
Go to System Preference - Privacy - General, In Advanced, There's a log out when inactive .... minutes option. That wil do.

Nov 20, 2015 3:49 AM in response to pbronzeby RobsonRott,I don't think so. It logs off while I'm working, not when it's inactive.

Nov 20, 2015 12:58 PM in response to Paul Hodson3by drubarth,Had same issue with the logout, plus display corruption.
Solved!
Setup
Mac Pro early 2009 16GB, 2 GTI 120 graphic cards, each with an ASUS 23" monitor connected with DVI.
Solution
Installed OS X 10.11.2 Beta
Using OSX default graphic driver (Nvidia Driver Manager doesn't not allow this version of OS to use its driver) but regardless it's stable with the default graphic driver from Apple!
I had also upgraded the driver for the video card, but that alone didn't fix the problem. Installed the CUDA software, but that didn't fix the problem. Tried unchecking separate spaces, but that too didn't fix the problem. It wasn't until I upgraded to the beta release that the issue was fixed. Not sure if the solution requires the beta release plus one of the other steps or not.
What a relief! Hope this works for others.

Nov 28, 2015 4:40 PM in response to Paul Hodson3by holli1966,I got this problem after flash player update.
After I removed flash player the problem was gone.

Nov 30, 2015 6:54 AM in response to holli1966by Holmez78,I never install FlashPlayer, and I have always had this problem.
Had this issue since El Capitan Beta1 was released for developers, and still have this issue today.

Dec 4, 2015 1:38 PM in response to JCrebbinby bollinger_joe,Thanks for saving my day! Updated another computer in the office without issues so thought it was safe on mine. Am running 2009 mac pro with six core W3690 xeon and flashed to 5,1. Was running dual monitors with separate graphics card. Upgraded to El Capitan and saw repeated system crashes and log outs. Turned of "Displays have separate spaces" and seems stable now (only been an hour or so).

Dec 4, 2015 6:33 PM in response to drubarthby jkhademi,I also updated another non-key computer to el Cap, no problems.
Updated my production 2009 MacPro, two displays etc...to El Cap...bricked it...as drubarth and others described.
Updated to Beta 5, holding my breath and not touching a thing as it downloaded and it seems stable.
Even re-enabled "Displays have separate Spaces."

Dec 8, 2015 11:11 AM in response to jkhademiby Dominick Saponaro,10.11.2 Final Public Release is out. Anyone want to post their experience. Still issues with multiple displays attached to more than one geforce 120 cards crashing to login screen?

Dec 8, 2015 11:41 AM in response to Dominick Saponaroby jeepster33,I just installed 10.11.2 on my 2009 Mac Pro with two GT120 cards. I moved the 2nd display back to the other card ( one display on each card ) and it has been working fine so far -- in the past, i wouldn't even be able to get to safari to type this. I hope it helps everyone else as well.

Dec 8, 2015 12:48 PM in response to jeepster33by Dominick Saponaro,Seems pretty good here too. Been up for an hour and a half so far with three monitors plugged into 2 geforce cards in an early mac pro 2009.

Dec 8, 2015 5:50 PM in response to Paul Hodson3by MacProUserGrateful,I got on here to thank JCrebbin for the info about mission control and the checked boxes. I have been in a month of **** dealing with an upgrade of El Capitan that blew my logic board from the heat from it shutting down in the middle of the install or maybe right after and it has never run since. 300.00 for the logic board, 300 for a harddrive to salvage the files the crash could have cost me, which didn't but it took a lot of time and buying diagnostics like a heat indicator and techtool pro. plus other things that probably amount to 300 is software upgrades. Culling my files for many all nighters getting rid of everything I could which was a pretty good thing and thousands of searches. talking to apple techs, two apple stores talking to geniuses who had never heard of this problem. I can't understand that. It seems such a common problem. A few days ago I talked with the nicest person at apple who helped me for so long on the phone. He wanted to help so badly and finally diagnosed it as a software issue after he had tried everything all the time we were cut off every minute or two with the log in crashes. After a month of these crashes I feel I have PTSD and I'm not joking. Then I finally stumbled upon this thread when doing some searches out of the crash logs and walla the right word combos bring up JCrebbin's post and I uncheck three boxes and now my computer is at peace and I can do my laundry. OMG I am so grateful to JCrebbin. I don't know how to write this person but will let him know if he is not reading this thread? Thank you. Thank you.

Dec 9, 2015 10:28 AM in response to Paul Hodson3by Kirk Kaplan,Promising. Updated to 10.11.2, updated Nvidia drivers, turned back on "Displays Have Separate Spaces, and.... drumroll... so far so good, Stable behavior. No logouts, even when passing cursor back and forth repeatedly between screens. (two cards, one screen on each; early 2009 Mac Pro). Fingers, eyes, toes crossed.

Dec 9, 2015 5:48 PM in response to Paul Hodson3by fsaurmann,So far so good on my end. Two GT120 cards, two screens. All has been well for the past several hours working in several applications. It seems to be remedied. Will be testing on another MacPro configured in a similar way later.
