If you are not getting a login screen at all, then it is likely a GDM issue. If you are getting a login screen and then getting the black screen after trying to login then it is also likely a GDM issue. Do you have a mouse pointer? Try booting into GNOME and see what happens. Also try switching vitrual consoles, control + Alt + F4 If you get a login prompt login and then run `startx` to launch a X-11 session. > > >> Enviado do meu iPhone >> > > > -- > ⢀⣴⠾⠻⢶⣦⠀ > ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system > ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ > ⠈⠳⣄⠀⠀ > > > -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄⠀⠀
