Laptop - Sony VAIO VGN-SZ71E
Ubuntu - 8.10 updated up to 4th Nov 2008.

On Stamina mode, so using Intel graphics, which is Intel

I confirm that in order to get dimming working all I need to do is to run this command:

xrandr --output LVDS --set BACKLIGHT_CONTROL native

And I do not need xbacklight, nor need to restart acpi. Just run the above command, the screen then blank out for half a second and back, and then I am able to use the Fn-F5/F6 to increase/decrease brightness on my Sony (finally...was going blind from the brightness, which is very extreme on a week-old laptop)

I've not attempted nvidia on Speed yet so will read the other bug report (it's not exactly needed...until I start putting on games that is :D)
