When booting Lubuntu 14.04, a terminal screen is shown instead of the usual graphical log-in screen. Then, I have to type sudo lightdm and use Ctrl+Alt+F7 to switch to the graphical log-in screen.

I checked cat /etc/X11/default-display-manager as described on https://askubuntu.com/a/84485/288322; this included /usr/sbin/lightdm already. I also did as described on https://askubuntu.com/a/457694; that works fine.

How can I repair the system so that it automatically boots the graphical log-in screen again?

Run the following command in terminal:

sudo gedit /etc/default/grub

This opens Grub boot loader config file with text editor.

Do below changes:

Uncomment the line #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", by removing # at the beginning, which will enable the Ubuntu purple screen.

Change GRUB_CMDLINE_LINUX="text" to GRUB_CMDLINE_LINUX="", this makes Ubuntu boot into Graphical Mode.

Comment this line #GRUB_TERMINAL=console, by adding the # to the beginning.

After saved the changes, update grub via command:

sudo update-grub

Restart your computer and see the result.
