Comment 9 for bug 1893302

Still see the same problem with Ubuntu Studio 22.04.1 LTS.
In my case it looks like I can reproduce it just by waiting.
So if I boot and make a coffee I can't login but if I then reboot and login immediately, all is fine.

Nov 12 09:26:13 hostname sddm[1676]: Greeter starting...

/var/log/syslog:Nov 12 09:26:19 hostname sddm[1676]: Greeter stopped.

will now try to install the missing hunspell dictionary and see if things still fail.
