X Window does not automatically open at start

[themostunoriginalname]

Currently, when I open my computer, it goes to the command line and I have to write startx to start it. Is there anyway to start it automatically again?

[picpak]

sudo update-rc.d gdm defaults

should do it.

/etc/init.d/gdm does not exists

[picpak]

sudo apt-get install gdm

works! Thanks!
