If the screen works during bootup but then stops working once the OS is
loaded, you might check to see if the little switch that detects
whether the screen is closed is stuck. That happened to my Dell laptop
and it would only work with the external monitor. Apparently, the OS
thinks that the laptop is closed and shuts down the LCD.

Fn+F7 (&F3)
I've been trying that. So... My free system may indeed be broken.
or a hook is missing in the OS, if that function needs to operate at
that level.
