I do have a multiseat-setup with 2 Monitors, mice and keyboards running for a long time. From time to time it broke with different reasons. In had to change driver, or the configs … but the it did work again for a while.
Now it is broken again after the last updates. On boot lightdm wont start on both seats, but only on one seat. Today it took lightdm more then 10 tries to get this one seat up.
maybe this is related too

The behavior is strange:
lightdm tries several times to start. in some cases even the login-dialog apears for a few seconds, and then disapears again. After 5 … 15 tries, lightdm succeeds, and the login-dialog stays on screen. then i can login.
But meanwhile the second seat does nothing any more.
