can't manage to copy-past or allow clipboard in the lock screen

[MichaelREMY2018]

hi,
i allow clipboard and teamviewer.
from my host , i put somethink in the clipboard, but once i went into SEB at sreenlock where i need to paste the password to unlock the bad-ending seb previous session it does not work. nothing is pasted, nothing is allow to enter text in input box.

i don't know why, but i can't enter text into any input box from a remote-distant session. why ?

At least, is there a way to desable the lockscreen from log or other parameter ?
