Version: 1.10.3-3
Severity: normal
Dear Maintainer,
until today I had not even tried this, when I typed 'root' and the password into the
lightdm-mask instead of into VT-4-login.
I was quite surprised, that lightdm allows root-login, I also did not find, where to
switch this off in the text-configuration.
I have tried some things about X-login, but a root-session from lightdm is clearly not
what I wanted.
In my opinion this is *INSECURE*, if I need graphical root-access, then I start thunar
for instance from the terminal, saying 'sudo thunar', but having a completely
root-Xsession is most probably not recommended at all.
Please revert this to normal and add a configuration-option to enable it, if hackers need
the it in order to test X-security.
Maybe this is related to systemd.
