HP Pavilion lid switch not working in sysfs (and dbus, evtest, kde)

Hello everyone,

My HP Pavilion laptop's Lid switch seems to be mishandled somewhere. The tangible effect is that I can't get my laptop to suspend upon closing the lid.

A call to

cat /proc/acpi/button/lid/LID0/state

returns the correct state ("closed" when the lid is closed, "open" when it is open).

However, evtest never receives any event:

$ evtest /dev/input/event0
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x5 version 0x0
Input device name: "Lid Switch"
Supported events:
  Event type 0 (EV_SYN)
  Event type 5 (EV_SW)
    Event code 0 (SW_LID) state 0
Properties:
Testing ... (interrupt to exit)

The alternatives exposed here involving dbus don't seem to work either:

$ dbus-send --system --print-reply=literal --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.DBus.Properties.Get string:org.freedesktop.login1.Manager string:LidClosed | awk 'NR==1{print $3=="true"?"closed":"open"}'

always returns "open".

Does anyone have an idea on how to solve this? A workaround (so that my kde's powerdevil would use /proc instead, for instance) would also help.

Thanks in advance!
