Bug Description

The system goes to sleep properly when the lid is closed, but when it is opened, it doesn't wake up again until the power button is pressed. When it is pressed, it wakes up properly.

/proc/acpi/wakeup contains:

Hi Matt,

It seems interesting that the LID device isn't listed in /proc/acpi/wakeup . Just curious what the state of /proc/acpi/button/lid/LID/state is before and after the suspend/resume cycle? What happens if you don't initiate the suspend by closing the lid, eg. using the fast user switch applet instead?

"On my aceraspire one it did the same thing in linpus lite so I'm
assuming that it is a expected behaviour hope that helps :)"

@Leann: it shows "open" before and after. If I disable the automatic suspend, and poll /state while closing and opening the lid, it correctly transitions from open to closed to open. The lid switch seems definitely to be working, it simply doesn't trigger a wakeup.

@mdz -- can we get the DSDT off the machine and attach it to this bug please.

    cat /proc/acpi/dstd >DSDT

From testing by davmor2, this is the same behavior exhibited by the default Linpus install. Thus Ubuntu is acting consistently with the default OS install on this hardware.

Thanks, Ronald. Marking as invalid based on the fact that this is a hardware issue and not Ubuntu.
