High!
I've just installed Linux to my old Laptop Sony Vaio VGN-SZ7 (aka
PCG-6W4P) and discovered strange behavior:
When the lid is closed - acpi does not know about it, acpi_listen
doesn't output anything, but such script:
while true;
do sleep 1;
cat /proc/acpi/button/lid/LID0/state;
done
outputs closed or opened, regarding to lid physical state. That means
that lid works and recognized by linux kernel, but acpi doesn't catch
lid events.
Also: $ dmesg |grep -i lid

Kernel version 4.2 (tested on 2.6.32 (ubuntu 8.04) - the same story).
Different distros result the same.
PS: I have sent the same letter on 26 of January, but due to thunderbird
crash it seems that it was not delivered (according to marc.info). SO I
send it again
Kind regards,
