[ltp] ACPI problem ...

[Romuald Fleury]

hi,

I try to use ibm-acpi, ibm_acpi module is installed and the package and
scripts are ok.

My problem :
When i try to change content of /proc/acpi/ibm files, system says i do 
not have the permission ( as root ... )

alca@foo:/proc/acpi/ibm $ sudo echo "on" > light
-bash: light: Permission denied

alca@foo:/proc/acpi/ibm $ sudo echo disabled > hotkey
-bash: hotkey: Permission denied

another things, if i do :
alca@foo:/proc/acpi $ sudo cat event
ibm/hotkey HKEY 00000080 00001004
ibm/hotkey HKEY 00000080 00001003
ibm/hotkey HKEY 00000080 00001003

i see the event each time i use ALT+F3, but only once for ALT-F4...

i use debian/sarge with 2.6.11rc4 kernel

thx for your help !
