Log in function Ubuntu

[nberto72]

Good morning everyone.

I have installed 4.8.2 for some time now.
all functions work except login.

To view the login screen on the master I had to install lightdm on the servers.
Furthermore, only very few times is the login successful.

Most of the time password fails.
I tried the nomodtweak and noxkb options but to no avail.
Can someone help me?
A thousand thanks.
