I recently updated my Kali to Sana and I am unable to login as root using my old credentials.
I am able to login to the Console with the same username and password but I am not able to login using the GUI interface (gdm3).
I tried changing the password from console and still no change.
I also created a new account and tried logging in using the new account but still no use. I also tried to Autologin by editing
/etc/gdm3/daemon.conf but still no effect.
