[Bug 376793] Re: HP 2140 Lid Close Not Detected

[João Gomes]

sorry, I explained it wrong.

I didn't meant to say that the workaround creates a new problem.
What I wanted to say is that what causes this problem also prevents the monitor from going to sleep.
Both problems seems to have the same cause.

By the way, I cannot apply the workaround.
It says "permission denied", even if I use sudo.

$ sudo echo 1 > /proc/acpi/video/GFX0/DOS
bash: /proc/acpi/video/GFX0/DOS: Permission denied
$ sudo echo 0 > /proc/acpi/video/GFX0/DOS
bash: /proc/acpi/video/GFX0/DOS: Permission denied

I also noticed another thing.
If I do the following (as explained in https://bugzilla.redhat.com/show_bug.cgi?id=512958) it recognizes correctly if the lid is closed or open.

$ cat /proc/acpi/button/lid/LID/state 
state:      closed
$ cat /proc/acpi/button/lid/LID/state 
state:      open

But the output of the gnome-power-manager in verbose mode (and with the
lid open) says that the lid is closed:

TI:12:09:52	TH:0x8a7e8b8	FI:gpm-idle.c	FN:gpm_idle_set_mode,108
 - Doing a state transition: normal
TI:12:09:52	TH:0x8a7e8b8	FI:gpm-manager.c	FN:gpm_manager_idle_changed_cb,804
 - lid is closed, so we are ignoring ->NORMAL state changes
TI:12:09:52	TH:0x8a7e8b8	FI:gpm-idle.c	FN:gpm_idle_evaluate,192
 - X not idle
