DanMcQ Posted May 14, 2015 Share Posted May 14, 2015 I recently installed a GTX 960 in my system running 10.10.3. Shortly after installing the new card, I started experiencing an issue in which the system would randomly close out all running applications and drop to the login screen. This was happening several times a day, and without any discernible rhyme or reason (it happened both while running graphics intense apps as well as normal system operation). Based on my review of the logs, it looks like the WindowServer process was crashing, with numerous references to both the OS X and nVidia drivers in the crash logs. Last night I put my old GTX 650 card back in the system and uninstalled the nVidia web drivers (I was running the latest version - 346.01.02f03). I have yet to experience the issue again, leading me to believe that it was probably related to the nVidia web drivers. Has anyone else experienced the same thing? I would really like to use the GTX 960 in my system, but the sporadic logouts are definitely a deal-breaker. Any thoughts or insight would be greatly appreciated!

WaldMeister Posted May 14, 2015 Share Posted May 14, 2015 Hi, I have this issue when using Quicktime/Youtube now and then. Whenever i switch to full screen, the same thing as described in your post occurs. This however happens on the Intel HD4600. After some research i found that this sometimes even happens on real Macs. No idea what causes it. Link to comment Share on other sites More sharing options...

Whenever i switch to full screen, the same thing as described in your post occurs. This however happens on the Intel HD4600. After some research i found that this sometimes even happens on real Macs. No idea what causes it. I think I've found a fix for my issue - avoiding the HDMI port on my graphics card. I have two monitors. The first is hooked up via the GPU's DVI port and the other via the HDMI port. Since I stopped using the HDMI port for the second monitor, I haven't had a single random logout (the monitor is now connected via DisplayPort -> DVI). Hope this helps.
