It looks like you are using a laptop. I had a similar problem when I
transfered my lfs install from my p4 desktop to my corei5 laptop.
Everything seemed to be working, but I couldn't see anything. The trick
was that backlight was set to zero. Pressing "Brightness Up" key brought
up the display.

Permanent solution was to add "acpi_osi=Linux acpi_backlight=vendor" to
the kernel command line (in grub.cfg after root=...)
