Thanks for your answers everybody!
So, I got it working by adding

video=i915:modeset=1

to the GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

I also want to add that I don't see happening what Matthew wrote. I can see all the boot messages while the machine boots, and after the machine reaches login prompt. Even now, from the X session, if I press CTRL-F1 I get to the console where there are the boot messages, and at the bottom, the login prompt.

Cheers,
Giorgos
