- Caught exception on dellLcdBrightness

Hi,

As stated in the title, this is a newbie asking.

When using the script dellLcdBrightness, to try to set the
brightness
value of my LCD screen, I've ran into the following error:

~$ sudo dellLcdBrightness -a -v 4
Read AC Mode Setting
    current: 7
    min: 0
    max: 7

Write AC Mode Setting
An Error occurred. The Error message is:
Unsupported SMI call.

I'm using a Vostro 1000 with a Turion 64 CPU. It is a dual
boot on
Windows XP and Ubuntu 7.04; I've been trying to use the
script
dellLcdBrightness because the brightness keys are behaving
strangely
on Ubuntu (they work fine under winXP).

Is that because I'm on a 64 bit kernel ? What could cause
that error ?
Any ideas on where to look for ?

Please make sure you have loaded the 'dcdbas' kernel
module.

dcdbas is correctly loaded, so says lsmod. This did not
change the
"unsupported SMI call" error.

Any other ideas ?

leonelleonel-notebook:~$ lsmod  | grep dcd
dcdbas                 11056  0

leonelleonel-notebook:~$ sudo dellLcdBrightness -a -v 3
Read AC Mode Setting
   current: 4
       min: 0
       max: 7

Write AC Mode Setting
An Error occurred. The Error message is:
Unsupported SMI call.
leonelleonel-notebook:~$

Not all of the newest systems use this same interface.  It
sounds like
Dell Quickset for Windows learned the new tricks for these
systems,
but we haven't investigated the same for Linux yet.
