[Bug 641660] Re: screen brightness problems on laptops with 10.04

[cascagrossa]

Same on a dell vostro 3500 kubuntu 10.04, nvidia 310M, proprietary
driver (current) instaled Hardware Drivers Manager.

I can get function keys to work inserting <Option   "RegistryDwords"
"EnableBrightnessControl=1"> at <Device Section> of xorg.conf. Values in
</proc/acpi/video/PEGP/LCD/brightness> also changes accordingly, but
changing it manually, <echo -n 30 >/proc/acpi/video/PEGP/LCD/brightness>
only changes screen brightness when i hit any brightness key.

KDE Power Manager applet is not able to control brihgtness.
