Touching keyboard keys doesn't cause laptop to resume

[Miles Lane]

I am running Dapper with all the latest updates:
acpi 0.09-1
acpi-support 0.72
acpid 1.0.4-1ubuntu10

Description:
The logout dialog has a button for putting my laptop to sleep. When I move my mouse pointer over the button, text appears stating that I should be able to wake my laptop up by hitting any keyboard key or my power button. When I try hitting keyboard keys, nothing happens. I have to touch the little switch that is pressed when the laptop lid is closed.

Does pressing a key on the keyboard wake it under Windows?

[Miles Lane (miles-lane)]

Yes, touching the keyboard does wake the machine under Windows. IIRC, touching the mouse wakes under Windows as well.

[Tormod Volden (tormodvolden)]

I have seen this on a HP Compaq nx6110. I had to press the power button to make it resume. I don't know how it would be under Windows.

[Miles Lane (miles-lane)]

FWIW, my laptop is an HP dv1240us.

[Andrew Jorgensen (ajorg)]

My laptop doesn't resume on keboard but it doesn't under Windows either. Just thought I'd mention it in case someone forgot to verify the behavior under another OS.

[Gareth Williams (gw-westdale)]

Still a problem in Hardy Heron on Compaq Presario laptop
One has to touch the power key to make the system resume from standby.

The comparison with Windows is not relevant to a user.
what matters is the original message as in the bug report:
either the keyboard should wake the system, or the message should be changed.

There is a (possibly related) worse problem in that once woken from deliberate standby or from powersave timeout in screensaver, the keyboard is dead. Separate bug report when I can find a suitable one.

This bug is a duplicate of 199006
The default status of PS/2 and USB keyboards in /proc/acpi/wakeup is set to 'disabled'.

This can be easily changed for example by running (as root):
echo "PS2K" > /proc/acpi/wakeup

Attached is a script that can be used to enable this support by default. I use it under /etc/acpi/suspend.d/
