I had a problem with power button on my Dell Optiplex GX270 in lucid (Server Edit.).
I just copied a old script:
# /etc/acpi/powerbtn.sh

from another machine (server too) and now it works perfect :)

$ cat /etc/acpi/powerbtn.sh
# /etc/acpi/powerbtn.sh
# Initiates a shutdown when the power putton has been
# pressed.

# Skip if we just in the middle of resuming.
test -f /var/lock/acpisleep && exit 0

# If gnome-power-manager or kded4 are running, let
# them handle policy This is effectively the same as 'acpi-support's
# '/usr/share/acpi-support/policy-funcs' file.

if pidof gnome-power-manager kded4 > /dev/null; then

# If all else failed, just initiate a plain shutdown.
/sbin/shutdown -h now "Power button pressed"

Expecting the computer to shut down once the power button was pressed. Instead the computer remained powered up and there was no text on the console. After investigating it appears to be an issue with the /etc/acpi/powerbtn.sh script.

Running "sudo /etc/acpi/powerbtn.sh" (which is referenced in /etc/acpi/events/powerbtn as the action) returns
.: 6: Can't open /usr/share/acpi-support/power-funcs

Replacing the line "action=/etc/acpi/powerbtn.sh" with "action=/sbin/poweroff" in /etc/acpi/events/powerbtn is a successfully workaround.
