[ltp] APM on R40e
30 Dec 2003 17:37:52 +0100
i'm using knoppix 3.3 too, but with kernel 2.6
battery status and shutdown is running correctly, but i can't switch my
lcd /on/off and i can't change the brightness and volume.
is something wrong in my kernel config?:
ACPI Support = y
sleep states = y
ac adappter = y
battery = y :)
fan = y
processor = n
asus = n
toshiba = n
debug statements = n
relaxed aml = n
