I recently updated my Kali box and after a reboot I can't sign in with the root account using the GUI, I've gone in with tty and single user mode and can sign in just fine there with the same password. I've even reset the password and still can't sign in. It just gives "Sorry, that didn't work. Please try again." like my password is wrong, but i've gone into tty and did a "passwd root" & passwd and reset it and can't get signed in.
