[Bug 1893302] Re: SDDM freezes on system boot

[Lassi]

Has been happening to me on several occasions. Caught logs just now.

SDDM seems fine at first for 3-4 seconds, but then the blinking cursor
from the password entry box disappears. Only mouse cursor moving in SDDM
greeter screen, but no interaction with any UI elements.

Can switch between virtual terminals.


In the attached logs it can be seen that the error happened at around 17:15 and 17:18-17:19.
Successful SDDM session at 17:27.

Seems that the following entry in syslog may be related, as it happens
just within the time frame when the text cursor disappears:

Dec  5 17:19:02 kaappi sddm-helper[1637]: [PAM] Closing session
Dec  5 17:19:02 kaappi sddm-helper[1637]: [PAM] Ended.
Dec  5 17:19:02 kaappi systemd[1]: session-1.scope: Succeeded.
Dec  5 17:19:02 kaappi sddm[1513]: Auth: sddm-helper exited with 9
Dec  5 17:19:02 kaappi sddm[1513]: Greeter stopped.

And that is present on both failing occasions (17:15 and 17:19). On the
last SDDM (re)start (17:27) there is no such log entry.

** Attachment added: "syslog showing 2 cases of error, last one is success."
