18.04 Switch users stops working after a while












0















After a reboot, I am generally able to switch users, and this works for a while. However, after some time the switch user option returns me to the password dialogue for the current user, and clicking the "Switch to another use" link on the password screen returns me to the password screen.



I need to change user without having to reboot to reset this functionality. How do I do that?



This from my auth.log

I tailed the syslog and saw this.
