Q: Mac Pro keeps logging out since El Capitan

Oct 2, 2015 9:12 AMby jessefromtuolumne,I've always had really poor performance issues when plugging two monitors into one GT 120 card. Do you notice performance degradation? Choppy animations, lagging scrolling, dragging, refreshing, etc.. with two monitors in one card?
I have four GT 120 cards on hand, but only generally use two of them, one monitor in each. I'd follow suit and put two monitors in one card, but for some reason it is really poor performance.

I guess any performance issues Ive always chalked up to the aging machine not specifically the cards with two monitors. Ive never noticed a difference using the single monitor hooked to one card versus the other two plugged in together while using a 3 monitor set up. As of right now I have two displays plugged into one card and the other monitor is disconnected to avoid the crashing. Seems to be acceptable performance. Maybe others can comment.

Oct 2, 2015 10:07 AMby BaronIstefan,Hi, same issue here with two monitors plugged into the GT120. The performance is somewhat sluggish, and forget doing anything that requires some graphics power. The card is old and only has 512MB, so that is part of the problem. If Apple does not fix the problem over the weekend, I might just buy a new GTX 970 card, which has 4GB and two DVI heads.
Regards,
Brian

Oct 2, 2015 11:35 AMby kausm,I have the same problem. I have a 2010 Mac Pro connected to two external displays (Dell and Asus) via DVI. This morning it kept logging me off and wouldn't let me do anything. I'm working from home now. Don't remember specifics of the Mac Pro. I know it has 8 cores and 16G RAM. I'm not sure of the graphics cards. I couldn't send an error report. Hope someone from Apple is reading this forum.

Oct 2, 2015 2:19 PMby alexjung,had same problem. downloaded Nvidia's latest graphics driver.
http://www.nvidia.com/download/driverResults.aspx/92173/en-us
restarted after installing, and haven't had a log out in a good while. probably not sufficient time to be definitive yet, but enough to make a noticeable difference since it used to happen every few minutes (if not seconds) for me previously.

Oct 3, 2015 5:18 AMby JCrebbin,HelpfulTry disabling 'Displays have separate spaces' in System Preferences: Mission Control.
This was causing the crash / log out error for me.
I have a triple monitor setup and noticed that after enabling the separate spaces, that the third screen desktop background changed to a different image. This caused log outs and even a kernel panic.
