[Bug 44825] lid state remains "closed" after suspend/resume

[cy]

Public bug reported:

As reported in this thread:
http://www.ubuntuforums.org/showthread.php?t=173864&highlight=lid since
~ May 8 suspending some laptops

- after given time
- on lid close

does not seem to work any more.

Suspending manually using key compination works fine.

Please give me some hints what information/debug info/console info/...
is needed to work on this, I'll try to provide any information I can
deliver.

After rebooting I checked the lid state again, closed the display -> entered suspend mode without problems -> reopened display -> checked state again:
Code:

cywhale at ubuntu:~$ cat /proc/acpi/button/lid/*/state state: open

suspending,resuming

cywhale at ubuntu:~$ cat /proc/acpi/button/lid/*/state state: closed

So the lid state remains "closed" after reopening the display, therefore
suspending won't work any more ?


Maybe the remaining lid state "closed" is caused by a missing lid-open or resume event ?

sudo acpi_listen
Password: ...
<closing>
<waiting 10-20 sec.>
<opening>
button/lid LID 00000080 00000001

Shouldn't there be 2 events, one for closing the lid and one for
opening/resuming ?
