Hi, I'm running Ubuntu Server 8.04.1, all latest updates on an HP Compaq
nx8220 Notebook. Seem like this bug is still not fixed, as my console
screen blanks, but the backlight stays on. Very annoying.

Note, that I had to use the vanilla Desktop Kernel, as the special
server kernel does not work on machines without PAE (see Bug #151942)

While googling I found this link, which describes the exact same problem. Unfortunaltely I have no idea of kernel configuration, but it might help to check if "Power management options >> ACPI (Advanced Configuration and Power Interface) Support >> Video" Kernel config is enables in the current Kernel.
The link: http://tinymicros.com/wiki/Laptop_LCD_Backlight_Blanking.

Some info on my config:

uname -a: Linux cardassia 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux
Kenel: Ubuntu 2.6.24-19.36-generic
