HP Folio 13: Lid close event is never fired => no suspend on lid close

Just tested on mainline kernel (3.4.0-030400-generic), the behaviour is the same.

Tested with 3.5 kernel as instructed, no change observed.

This sucks, so I wrote a little script that works around the issue. It's a little program that runs as root, checks to see if the lid is closed every two seconds and calls pm-suspend. There's probably a better way, this just worked for me:

Nice workaround, thanks. Moreover, as this notebooks tends to wake up on its own right after a suspend, this scripts puts it to sleep again while the lid is closed. The only drawback is that it doesn't lock the screen.

Still does not work out of the box with 12.10

Same behaviour as in bug description for me:

$ acpi_listen
ibm/hotkey HKEY 00000080 00001018
button/lid LID 00000080 00000006
button/lid LID 00000080 00000007

$ while sleep 1; do cat /proc/acpi/button/lid/*/state; done
state: open
state: open
state: open
state: closed
state: closed
state: closed
state: closed
state: closed
state: open

On a Lenovo Thinkpad T520.

Any plans to correct this bug?

This seems to have been fixed some time ago. At least fixed in Ubuntu 13.10 saucy.

If it had indeed gone away (it was still present for me in 13.10), it has returned in 14.04 beta2.

Machine is an HP Folio 13.
$ uname -a
Linux HP-Notebook 3.13.0-20-generic #42-Ubuntu SMP Fri Mar 28 09:57:00 UTC 2014 i686 i686 i686 GNU/Linux

Same behaviour as reported JThoennes, gpothier

This is definitely not fixed, and continues to persist on every version of Ubuntu from 12.04 to 14.04. My workaround (linked above) still works.

Reopening.... It's OK in this case because no explicit fix was applied and documented in any package.

Looks like I have the same problem on a Sony Vaio SVP132A1CL, ubuntustudio 14.04.3 LTS.

# dmesg | grep -i lid:

[closing lid does nothing]

Interestingly, there are no other buttons defined in /proc/acpi/button/. There doesn't seem to be any activity on /dev/input/event0.

Workaround to lock screen on lid close (run in Settings manager/Session and start-up/Application Autostart):

#!/bin/sh
while :
do
 while grep -q close /proc/acpi/button/lid/LID0/state
  do sleep 5; done
 #echo "close->open"
 while grep -q open /proc/acpi/button/lid/LID0/state
  do sleep 1; done
 #echo "open->close"
 xflock4
done

Hope this helps.
