Thread: Lidbtn ACPI event never triggered, backlight doesn't turn off

-

i'm having problem laptop lid in ubuntu 9.04. lidbtn event never triggered when lid closed. /proc/acpi/button/lid/lid0/state reports proper states (open or closed), lid.sh script never executed.

laptop dell studio 1555.

can confirm because backlight not turn off when close lid, if have running:
code:
while [ 1 ]; /etc/acpi/lid.sh; sleep 1; done
the backlight turns off when lid closed, , on when open it. ideas? making me crazy :[

same problem here... dell studio 1555.

can make laptop suspend? did install kernel 64-bit?
