Package: lightdm
Version: 1.18.3-1
Severity: important

Dear Maintainer,

Lightdm freezes randomly while locking. This is from the log:

Mar  4 13:26:48 ... org.a11y.atspi.Registry[1482]: XIO:  fatal IO error 11
(Resource temporarily unavailable) on X server ":0"
Mar  4 13:26:48 ... org.a11y.atspi.Registry[1482]:       after 12005 requests
(12005 known processed) with 0 events remaining.
Mar  4 13:26:49 ... org.a11y.atspi.Registry[13268]: XIO:  fatal IO error 11
(Resource temporarily unavailable) on X server ":0"
Mar  4 13:26:49 ... org.a11y.atspi.Registry[13268]:       after 12021 requests
(12021 known processed) with 0 events remaining.

This continues till i press Ctrl+Alt+F7:

Mar  4 13:26:56 ... lightdm[19654]: session_get_login1_session_id: assertion
'session != NULL' failed
Mar  4 13:26:56 ... lightdm[19654]: Error getting user list from
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
org.freedesktop.Accounts was not provided by any .service files

The login screen appears but all apps closed after logging in.

Kind regards,
John Kirk
