[Bug 77739] Re: LCD brightness setting doesn't work with Sony Vaio VGN-S5M

[LaurentAlmeras]

fdi policy file is right. I download it and it is the same I keep here.
The only problem I have is that if I click on the link, Firefox try to
open the file (because it is xml) and only displays text nodes. So I
need to right click and download.

You're right for the shift on brightness value. So the
laptop_panel.num_levels needs to be set to 20 in my fdi policy file.

I don't have the strange problem you describe. When does it happen ?
When you use smartdimmer in a terminal ? With the power management
applet ?

You should give your
"/org/freedesktop/Hal/devices/computer:smbios.system.product" property
pour fdi policy file, in case Ubuntu packagers decide to integrate this
workaround.
