dell xps 1530: keyboard volume buttons don't work

[Lishai Eitan]

The Raise Volume and Lower Volume buttons do not work in kubuntu 8.10 on Dell xps m1530 (Live CD).
When I press one of the buttons, the volume bor is shown, but the volume stays the same.
When I assign the keys as global shortcuts to kmix's raise volume of the "Front" channel, the volume is still not changed and the volume bar is NOT shown.
When I assign the keys to kmix's raise volume of any OTHER channel, the volume IS changed, but the volume bar IS NOT displayed.

I noticed that kmix lists under "select master channel" TWO "Front" channels.
in kubuntu 8.04 it listed one Front channel and one Master channel.

thank for you report but to be able to fix the hotkeys on your laptop we need three things:

   1. What the key *should* do.
   2. What keycode (magic number) the key produces on your laptop.
   3. How to identify your laptop by the manufacturer and model.

You can see the following documentation to know how to do that:
https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch

Moreover, this bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage.
I have classified this bug as a bug in acpi.

Waiting for the wanted information.

1. The keys should raise / lower the volume, preferably showing a volume bar on screen.
