[Bug 568611] Re: Screen brightness control fails on Dell Studio 1558

 

Working fine on my HP Pavilion DV3 2155mx.

I needed to add the "acpi_backlight=vendor" boot parameter.

As reported in comment #87, the gnome brightness panel does not work but
the function keys work perfectly.

Thanks, Kamal! You've fixed an issue that I've had since I first tried
Ubuntu on this laptop (9.04).
