Q: Mac Pro keeps logging out since El Capitan

My big box has two GT120 cards. Monitors= 2 Samsung 26", 1 Ausus High Def 30", and one 22.5" "something else" with dual link DVI. You did not indicate how many monitors on your cards.  The 5770 is at least $200, so that is more than I will pay to "upgrade", especially with the marginal operational improvement that EC provides. EC runs fast on my 13" MBA i7 (2013), but not so fast on my mid 2010, 21.5" iMac with 3 ghz i3.  Big Box 3.1 MP has 8 core and 12 gigs, but is currently really bogged with Yose.  Enough to rate the title of "current POS".  It is geeked at 50% faster than the MBA, but reality is the MBA is outperforming the Big Box. Go figure.

I'm prepared to declare victory ... how about you?

Installing the third version of the beta of OS X 10.11.2 that was released on November 11 made all the difference. The only way to stay logged in since El Capitan was released on October 1 was to keep my hands off the controls so the cursor stayed stationary ... not very productive. After installing the 3rd version of the beta all is well ... just like it was under Yosemite.

Unfortunately, the only solution for now is to be running beta software, which comes with additional risks, not to mention the hassle of registering as a beta tester with Apple, downloading and installing beta software and hoping no new problems are introduced.

Been running for the past 2 days no problem with having two monitors connected each to a NVIDIA GeForce GT 120 512 MB card.

I agree!

Victory is declared

I have EC installed on a separate drive and booted it last night, updated the OS and then updated the NVIDIA drivers and it worked for over two hours. Config:

Mac Pro 3.1

2 x NVIDIA GeForce 8800 GT with 2 Monitors on each card.

I can't afford to lose time during the day so using Yosemite for Production work during the day. I'll try it again tonight and over the weekend and if it works ok I'll use for my production again. But it looks like a real fix to me!

So the fix is in?

With spaces operating?

With EC beta and Nvidia beta?

My second monitor has been shut down, I've been watching and things were looking good so I struggled with one monitor not wanting to reinstall Yosemite.

I've been having the same issue since upgrading to El Capitan. Hoping for a solution, I've installed 10.11.2 Beta 3.

Within less than 5 minutes, another logout happened.

*sigh*

No hope for the solution yet.

What monitors and how are they connected?

I think you have a different problem

Have you downloaded and/or updated the Device Drivers too?

Everything updated.

1 monitor, LG IPS, HDMI connection.

It might differ from MacPro`s, since it's only one monitor, but it's the same annoying issue.

I agree, i have a mac pro early 2008 (3.1) with a ATI Radeon HD 2600 XT (256mb) and a NVIDIA Quadro FX 5600 (1.5gb); el capitan only works if i attach the two monitors i have to the same card, ATI or NVIDIA (i use NVIDIA obviously). Very annoying.

I have been running the 10.11.2 Beta (15C40a) for the past week and I have the Mac Pro Early 2009 with 2 NVIDIA GT 120 512 MB cards each connected to a 30" Apple Cinema and have had no problems with logging out.  I have Separate Spaces unchecked.

What if you check Separate Spaces?

Works since days with "Separate Spaces" ON!
