Ok, I've got your fdi file now, sorry. My smbios.system.product key is VGN-FE21M. But wouldn't it be preferable to detect the GPU ? I'm not sure but I think num_levels is 21 : 0.1.2...20 and 1.2.3...21 constitute 21 different levels. The problem (going to 0 then step up to the desired level) occurs when I change the brightness using hal (through gnome-power-manager), not when I invoke smartdimmer from the command line.
