Hi,

My new Lenovo IdeaPad S206 has a special button ("OneKey recovery system"
button) that I wanted to re-map to a sleep button.  I did this, and it
works well.  There is also a QS key, that one could profitably re-map.

Along the way realized that the generic IdeaPad mappings of the Ubuntu 12.10
distro are largely incompatible with the keys on this computer.
So I set out to remedy that.

I'm not sure I'm following best practices though.  In particular, should
existing IdeaPad rules be restricted, or should the mappings be overridden?

I have some evidence that the mappings here should also work for the S200,
but I'm pretty sure they *aren't* appropriate for the S205.

The OneKey button on this machine is perfect for a sleep button:
it is easily accessible, but impossible to press accidentally.

To simply re-map the OneKey button, I first observed:
A 0x10 press-release pair is emitted if the button is given a substantial
press, and released. After about 3 sec of continuous pressing,
a 0x11 press-release pair is emitted.

I put a rule like this under "keyboard_modulecheck":
  ________________________________
ENV{DMI_VENDOR}=="LENOVO*", KERNELS=="input*", ATTRS{name}=="Ideapad extra buttons", ATTR{[dmi/id]product_version}=="*S206|*S200", RUN+="keymap $name 0x10 sleep 0x11 hibernate"
  ________________________________
For the other keys, I have made a keymap file, which at least gets the proper
mappings going.  I'm not sure if I really improved anything.  See attached.

For one thing, some of the keys don't seem to make scan codes on any device
(the camera key on the F9 key.) Some seem to work regardless of how I map
them -- I guess that means they're going straight to hardware and the
system just reads the hardware state.

I'll be glad to hear what you think!

Hi,

In the previous post, I had confused the "win" key with the "switch video"
key.  This is corrected now.  See attached.

I still have several questions:

switch video
------------
The key meant to switch video (mod F10) produces two scan codes.
In man showkey, there are some remarks, but I don't know what they mean.

$ keymap -i /input/event4
	scan code: 0xDB
	scan code: 0x19
	(both scancodes emitted together only once on press,
	nothing on longer hold, nothing on release)
$ showkey -s
	0x19 on press
	0x99 on release

** What does this mean, and how are such results to be used with udev rules?

camera off-on
-------------
I can't see that this key (mod F9) generates anything on any device,
although it does in fact seem to kill the USB-based camera.

** Any ideas?

kill key
----------
The kill key (mod F4) very effectively kills any terminal it's running
in, so I have yet to determine what scan codes it generates.

** Any ideas?
