Logout issue - Beta drivers 2.6 and official drivers 2.6

ficestash · 09-21-2016, 02:50 PM

My band aid fix was to not use mission control to move to a new workspace. I upgraded to Mac OS Sierra this morning.

I moved my DVI cables and swapped connections so my middle monitor has the 60hz refresh rate. The left and right monitors have the 30 hz refresh rate now. I tried moving the next workspace to the the right, and the infamous Mac OS Logout issue occurred.

I found someone with the same issue. A response tells you how to get to the Mac system logs.

The issue doesn't occur when one monitor hooks up. It appears this error is an issue with the MacOS libdispatch client and the displaylink software.

I uninstalled the display link driver and rebooted. I've upgraded to a 2540x1440 monitor for my center monitor and am using a second 1920x1080p monitor. I'm happily using the Mission control and work spaces again. IMO this is a better solution for multi-tasking and productivity if you're experiencing any driver and Apple module issues like I have, and you don't want to take the mouse 30hz performance hit using the display link driver.
