Public bug reported:
I can check the reported state of my laptop lid's status (open or closed) via
two methods:
1) cat /proc/acpi/button/lid/LID/state
2) upower --dump
Whether the lid is closed or open is not always reported identically
between these two methods. On my laptop, after closing and opening the
lid, "upower --dump" will report the lid as closed, while
"/proc/acpi/button/lid/LID/state" correctly says the lid is open.
Using acpi_listen, my laptop generates lid events when the lid closes,
but not when it opens. I compared this to another laptop and the second
laptop generates laptop lid events both when opening and closing the
lid.
I was asked to re-file this bug against the linux kernel instead of
upower, as I originally did, and link the original bug here. So, here
is the original bug report with more information: Bug #561656
